Is it possible to soak peas. Soak peas with soda for soup, porridge or mashed potatoes

Important! When melting aluminum, use protective equipment: gloves, protective shoes, overalls, a respirator, special tools to avoid getting molten aluminum on the body. Molten metal can splatter on contact with water droplets and cause very dangerous burns. Be extremely careful! Finished melting furnaces in this shop.

blowtorch and aluminum

The video shows how you can melt aluminum at home using a simple blowtorch. The method is quite simple, it does not require blowing, which is necessary in cases where firewood, coals and other solid fuels are used to create the desired melting temperature of aluminum. The video clearly shows how the preparation of the necessary aluminum materials and the melting process itself are carried out.

In this video, another craftsman will present his model of a melting furnace and explain how to make a crucible for melting aluminum and prepare it for work.

And here the actual melting process is shown and good advice is given. Notice how the master is protected from injury.

Several methods to melt aluminum at home

I was inspired by the videos on YT, which are now full of every topic.

The concept of the simplest furnace needs improvement:

Casting aluminum cylinder:

And, of course, dozens of other similar films. Different furnaces, different burners, different fuels, different types of molds and many ways. You can do interesting things with it, in the sense of an aluminum copy of any object. I do not know, for example, to copy a specific latar, although this is more for advanced

So far I've made a 5 liter steel can, climbed 7 kg of fireclay mortar (the model plaster from the video is a bad material because it breaks quickly), the crucible is a 2" 15 cm cork with a 2" bottom plug, according to what I calculated is to introduce 900 g of alu or 3 kg of copper. 2 burners with 1/2" tube, the concept is very similar to film but 100% DIY with nozzles etc. Crucible 19 PLN, fireclay mortar 30 PLN – the current cost that I have incurred so ridiculously.

I'm in the first firing phase while I'm testing methane, today I heat the crucible to 695°C and I'd rather not expect more from this gas, maybe a little more after the next fixes. Ultimately, it should run on butane, which is several times more calorific than methane, but I have to make smaller nozzles. On methane, a 1mm nozzle works well, but on butane it is too much, the gas has too little velocity and does not "pull" enough atmospheric air. I'll try 0.6mm because I have the smallest drill.

The melting point of aluminum is 660°C, but you should have around 100° more to pour it later. Of course, with a steel crucible, the aluminum will be contaminated with steel from the crucible, but if we melt various elements, it will be a good combination of different metals and no one will build from this plane, so brittleness / ductility is of secondary importance here.

And of course there is the security issue, it's not fun and you could hurt yourself or someone else. From serious burns, to the terrifying occurrence of an explosion, to stupid zinc oxide or carbon monoxide poisoning.

As I will be interested in taking some photos, unfortunately I did not take them during construction, because it was just such an experiment, but it turned out that so far everything works better than I expected

Aluminum and duralumin waste is easy to melt literally at home. And for this it is not necessary to build blast furnaces, to create traction, as is customary in accordance with standard conditions.

The author of the method of melting aluminum on a gas stove uses a stainless steel ladle as a crucible. The melting point of aluminum is 660 degrees. A gas stove cannot provide such heating. First, within 15 minutes, the crucible with the contents warms up, then the gas burner is turned on, which provides the temperature required for aluminum melting. Finished melting furnaces in this shop.

Attention! Do not use such an unstable crucible as in this video. Be sure to use the hood, leave the window open and do not work at home with molten aluminum often.

What can be done using such melting furnaces? For example, as in on our website, you can make an aluminum model of weapons. This requires foam, sand and a smelter. By the way, the article also contains a link to an analogue of the smelter, which is presented here.

How to melt aluminum in survival conditions

Survival skills at your fingertips become incredibly invaluable! One skill that has unfortunately fallen by the wayside in recent years is the art of blacksmithing. Knowing how to melt down aluminum is an essential survival skill to master. You can't trust that in the indefinite future someone else will do it for you...you have to know how to create your own content.

Here's how to melt aluminum in your backyard.

Backyard. Blacksmithing: how to melt aluminum

The term DIY survival can be easily understood if taken literally. It just means that you can do most things on your own.

Having your own crucible will allow you to set up a small backyard metalworking industry (or bomb shelter). Aluminum alloys can be difficult to manufacture on their own. But having a stack of ingots made from molten aluminum can provide you with plenty of raw materials to build tools.

Luckily, with a little time, effort, and a few household items, you can build your own! Before melting starts, you need to produce a foundry. With your own foundry, you can melt down metals like aluminum and remake them into the tools you need. We have step by step instructions on how to build your own mini foundry and how to melt aluminum.

Check out the video tutorial below to learn how:

Once you create this smelter, you can do all sorts of things with it! Check out this short tutorial video below which shows you how to turn scrap aluminum into "cupcakes". Basically, cupcakes are made from molten aluminum. After melting your aluminum cans, you can turn them into a lot of great things that can be used for survival purposes.

Warning: This caster can reach temperatures over 1200 degrees Fahrenheit! Be sure to use all necessary safety equipment before attempting to use the foundry.

How to melt aluminum cans at home

Aluminum is a common and useful metal known for its corrosion resistance, malleability and light weight. It is safe enough to be used for food and skin contact. It is much easier to recycle this metal than to purify it from ore.

You can melt down old aluminum cans to get aluminum. Pour the metal into a suitable mold for making jewelry, tableware, ornaments, sculptures or other metalworking project. This is a great introduction to home recycling.

Materials for melting aluminum cans

Melting cans are not difficult, but this is an adult project because the high temperatures are involved. You'll want to work in a clean, well-ventilated area. It is not necessary to clean the jars before melting them, as the organics (plastic coating, residual soda, etc.) will burn during the process.

aluminum cans;
a small electric furnace oven (or other heat source that reaches an appropriate temperature, such as a propane burner);
a steel crucible (or another metal with a melting point much higher than aluminum, but lower than your oven), can be a sturdy stainless steel bowl or cast iron skillet);
heat resistant gloves;
metal tongs;
the molds into which you will pour the aluminum (steel, iron, etc. - be creative);

aluminum melting

The first step you want to take is to crush the jars so you can load as much as possible into the crucible. You will get about 1 pound of aluminum for every 40 cans. Load your jars into the container you are using as the crucible and place the crucible into the oven. Close the lid.
Run the furnace or furnace up to 1220°F. This is the melting point of aluminum (660.32°C, 1220.58°F), but below the melting point of steel. Aluminum will melt almost immediately after reaching this temperature. Allow half a minute or so at this temperature to make sure the aluminum is melted.
Wear safety goggles and heat resistant gloves. You should wear a long-sleeved shirt, long trousers, and toed shoes when working with extremely hot (or cold) materials.
Open the oven. Use tongs to slowly and carefully remove the crucible. Don't put your hand in the oven! It's a good idea to line the path from oven to mold with a metal pan or foil to help clean up spills.
Pour liquid aluminum into the mold. Aluminum can harden on its own. If desired, you can place the mold in a bucket of cold water after a few minutes. If you do this, be careful as steam will be produced.
There may be some residual material in your crucible. You can knock the trash out of the crucible by slamming it upside down on a hard surface like concrete. You can use the same process to knock aluminum out of molds. If you have problems, please change the mold temperature. Aluminum and mold (that's a different meta) will have a different coefficient of expansion, which you can use to your advantage when freeing one metal from another.
Don't forget to turn off the stove or oven when you're done. Recycling doesn't make much sense if you're wasting energy, right?

Aluminum is one of the most common metals on earth. It is present even in the human body, so what can we say about the surrounding reality. In every house or private car there are aluminum functional elements, parts or assemblies, which, alas, break quite often. These are furniture and window fittings, guides for doors and shutters, lock latches and other necessary little things.

They can be replaced with purchased new products, repaired or made independently. In the last two cases, you may need to melt aluminum at home.

Aluminum characteristics

It is not necessary to know all the characteristics of metal for homemade products. But there are a few things that can become significant or even dangerous at work.

Aluminum lends itself well to casting, melts at a relatively low temperature of 660 ° C. For reference: cast iron begins to melt at a temperature of 1100 ° C, and steel - 1300 ° C.

Therefore, melting aluminum at home on a gas stove is difficult to implement, since home gas appliances cannot provide such a temperature. True, domestic "kulibins" can do everything, but more on that later.

The melting point of aluminum can be reduced by grinding it into powder or by using a ready-made powder product as a raw material. But here another property of aluminum becomes important. It is a fairly active metal, which, when combined with atmospheric oxygen, can ignite or simply oxidize. And the melting point of aluminum oxide is more than 2000 ° C. During melting, the oxide is still formed, but in small quantities, it is he who forms the scale.

The same activity can play a bad joke if water gets into the molten metal. When this occurs, an explosion occurs. Therefore, if you need to add raw materials during the melting process, then you need to make sure that it is dry.

Raw materials for smelting

If aluminum is to be melted at home, due to the complexity of working with powder metal, it is not used as a raw material.

You can purchase an aluminum ingot or use ordinary aluminum wire, which is cut into small pieces with scissors and pressed tightly with pliers to reduce the contact area with air.

If a particularly high quality of the product is not expected, then any household items, tin cans without a bottom seam or profile trimming can be used as raw materials.

Secondary raw materials can be stained or stained, this is not a problem, the extra components will leave in the form of slag. Just remember that you can not inhale the vapors of burnt paint.

In order to obtain high-quality aluminum smelting at home from secondary raw materials, fluxes, the task of which is to bind and bring all impurities and impurities to the surface of the molten metal, are best purchased ready-made. But you can make it yourself from technical salts.

The coating flux is prepared from 10% cryolite and 45% sodium chloride and potassium chloride each.

An additional 25% of the total mass of sodium fluoride is added to the refining flux to obtain aluminum without porosity.

Personal protective equipment for melting

Melting aluminum at home is an unsafe process. Therefore, personal protective equipment (PPE) must be used. Even if such melting is needed once with minimal equipment, then at least you need to protect your hands, for example, with special welding gloves that perfectly protect against burns, because the temperature of liquid aluminum is more than 600 ° C.

It is also desirable to protect the eyes, especially if melting occurs often enough, with glasses or a mask. And ideally, you need to work in a special suit of a metallurgist with increased resistance to fire and high temperatures.

If you need very pure aluminum using a refining flux, then you should work in a chemical respirator.

Casting shape

If you only want to cast pure aluminum for soldering, then a mold is not needed. It is enough to use a steel sheet on which the molten metal will cool. But if you need to cast at least a simple part, then you need a mold.

The casting mold can be made from sculptural plaster, namely plaster, and not alabaster. Liquid gypsum is poured into an oiled mold, it is allowed to harden a little, shaking periodically to release air bubbles, a model is inserted into it and covered with a second container with gypsum. In a convenient place, you need to insert a cylindrical object into the plaster, so that as a result a hole appears in the mold, the so-called channel, into which molten aluminum will be poured. When the plaster finally hardens, the two parts of the form are separated, the model is removed, and the form with the finished cast is connected again.

It is also possible to make a casting mold from a mixture of 75% molding sand, 20% clay and 5% coal sand, which is poured into a special box of boards and rammed. The model is pressed into the compacted earth, the resulting print is sprinkled with talc and graphite (coal dust) so that the cooled aluminum part can be easily separated from the mold.

melting crucible

Melting aluminum at home requires a special container with a spout made of refractory material. This is the so-called crucible. Crucibles can be porcelain, quartz, steel, cast iron, corundum or graphite. At home, you can use a purchased crucible or make it, for example, from a piece of steel pipe of a sufficiently large diameter. True, this requires a grinder, a welding machine and the skills to use these tools.

The dimensions of the crucible depend on the required amount of aluminum to be melted. This bucket must be evenly heated, and its heat must be transferred to the raw material.

Smelting furnaces

The technology for melting aluminum at home is quite simple. In a special ladle, aluminum scrap is heated to a temperature exceeding the melting point of this metal, the melt is kept in a heated state for some time, slag is removed from its surface, then pure metal is poured into a mold for cooling. The melting time depends on the design of the furnace, that is, the temperature that it is able to provide.

If a blowtorch or gas burner is used, they heat the aluminum from above. True, at the same time, the furnace is still made up of bricks in a well without a binder solution, inside which coals will burn through to heat the container from below and keep it warm.

The design of the furnace looks approximately the same if the crucible is heated from below with the help of ordinary firewood and a hair dryer. Only in this case, firewood is laid in a brick well not on the bottom, but on a grate located on the first row of bricks, and in this row a hole is left for a metal pipe put on the neck of the hair dryer and fixed to it with electrical tape. The crucible in this case is a tin can, of course, not aluminum, in which diametrically opposite through holes are made at a small distance from the top. A steel bar is threaded through these holes, for which the can should be hung in the furnace. A hair dryer is needed to force hot air into the space between the bricks and the crucible. Sometimes a metal barrel is used instead of bricks.

If melting should take place quite often, then you can make a muffle furnace with a vertical crucible loading with your own hands or buy a ready-made one.

Melting with a blowtorch

Melting aluminum at home with a blowtorch should not take place indoors. In addition to raw materials, a blowtorch, crucibles and bricks, you need to prepare firewood, pliers and a steel bar.

So, a small well was made of bricks so that a ladle with aluminum and a small steel sheet could be installed on top. A fire is kindled in the well, which must burn out a little to form coals.
Further, in fact, the melting of aluminum takes place at home. Step by step process instruction:

A container with raw materials is installed on the bricks. It needs to be heated for about 15 minutes.

After that, the blowtorch burner is turned on at full power and the aluminum is heated from above.

The process begins within a few seconds, but in order for the heating to be uniform, the metal in the container must be gently mixed with a steel bar, holding it with pliers (while not forgetting to put on gloves). You can do without a rod, periodically shaking the bucket with the same pliers, but very carefully.

When the liquid becomes homogeneous, you need to take a container with pliers and pour the contents onto a calcined steel sheet so that all the scale formed remains in the ladle, and only pure metal gets on the solidification sheet.

This is how pure aluminum is usually obtained from secondary raw materials, if aluminum parts are to be soldered with it.

Smelting on wood or gas

Melting of aluminum at home on firewood takes place in lightweight collapsible furnaces. The disadvantage of this method is the uncontrollability of the process. It is not possible to increase or decrease the heating temperature. It is possible to intervene in the process only by removing the container with aluminum from the fire.

Melting aluminum at home on gas is the only possible option for an apartment. It is necessary to heat the container for a long time, periodically draining the molten metal. In this case, the casting is performed in layers. For work, you will need two metal containers of such diameters that one is put on the other. The smaller one serves as a crucible. It is placed with a crowbar, for example, cut aluminum wire, on a burner, from which it is necessary to remove the flame divider, a household gas stove. Larger capacity will have to be worked on first. About a dozen small holes are made in its bottom. Bolts are screwed into two or three of them, which act as handles, for which the red-hot container can be lifted with pliers.

This container is placed upside down on the crucible. This design allows you to warm up aluminum. Periodically, the upper container must be removed and scrap is mixed with a metal rod or knife. Before draining the molten metal, slag must be removed from its surface.

Melting aluminum in a muffle furnace

A muffle furnace is already quite serious equipment for obtaining high-quality molten metal. Therefore, when melting, a flux is used to clean aluminum from impurities. And this is already almost a production process, and not melting aluminum at home.
Step-by-step instructions also include several points for the preparation of raw materials:

First, the flux is melted in the crucible, which must be taken in an amount of 2 to 5% by weight of aluminum, and then scrap is added to it.
How active the flux can be determined by the surface of the melt - it must be mirror-like. If this is not the case, a little more flux is added to the melt, then it will need to be added before the end of the melt, so that the slag can be more easily removed from the metal surface with a steel spoon.
Melting should be carried out at approximately 700-750 ° C. This is the temperature of the red glow.
During the melting process, it may be necessary to add raw materials to the crucible, as the molten metal is greatly reduced in volume.
Refining flux is added, if necessary, at the end of the melt in an amount of 0.25% by weight of the molten metal. Maintaining such a proportion at home is not an easy task. After adding the flux, the melt must be stirred with a spoon, let stand for about 5 minutes, then remove the slag.
When, as a result of heating, aluminum has turned into a homogeneous shiny drop, the crucible must be kept in the furnace for some time so that the metal becomes more fluid.
Then aluminum from the crucible through the spout (at this moment it becomes clear why such a ladle is needed) is poured into the mold in a thin continuous stream.
After complete cooling, the mold is carefully divided into halves, the finished part is removed from it, which still needs to be finalized: drill holes, if necessary, clean and sand the surface with sandpaper. That's all. Process completed.

So do not be afraid in advance if you have to melt aluminum scrap at home in order to get clean metal or make a part to replace the broken one. Serious professional skills are not needed at all to organize such a foundry. The desire and skillful hands of an ordinary amateur craftsman can work wonders.

Many people came up with this idea, but few people did it. Consider how to melt aluminum at home.

Before starting work

First you need to decide on the size of the product and the amount of work:

For small ones, a gas stove is suitable.
For medium - homemade small refractory brick oven
For large ones - a muffle furnace.

With any choice, it is necessary to close the container with molten aluminum from drafts as much as possible and seal the walls as much as possible in order to reduce heat loss. Aluminum quickly gives off heat, so it is difficult to heat it in simple conditions. Let's see how to achieve this.

What technologies exist for melting metal?

When using a gas stove, you need to remove the existing flat nozzle and install a special device on top of the grate - a cylinder that can be made from any iron can of a suitable size. A 3-4 cm hole is made from the bottom of the cylinder, and 3 screws are screwed in - they are needed in order for the form with aluminum inside the cylinder to stand on them.

A torch will come out of the camphor, falling into the cylinder, it will heat the mold with metal. The cylinder is needed to save heat and maximize the concentration of the flame around the mold. From above it is buried with a plate so that the heat does not go away, but a small gap is left for traction.

For stoves, the same principle is used; large containers can be placed here due to minimal heat loss and a large space inside the stove. A small brazier is made, on which forms are placed, after which the oven is closed as much as possible from all sides, only small holes remain from below and above for traction.

The muffle furnace is the ideal home option for frequent jobs

The muffle furnace is similar to a simple "potbelly stove" only with thick walls. It can be both on wood and on electricity, to whom it is convenient. In the second case, the wire is pulled in a spiral from the inside of the bricks, closer to the shape.

Inside in the middle there is a crucible - a special container for melting metal. In this design, losses are minimized - the free space is occupied by the crucible, between which and the walls there is a small gap of 5-10 cm.

Due to the large thickness - 20-30 cm, the walls can be filled with various heat insulators to preserve heat. It can be transferred or made stationary, in connection with which, a heat insulator is selected. Inside there is a brick, outside - iron, and how to fill the rest of the space is at the discretion of each separately.

Metal melting

When melting, it is important to use clean utensils (made of iron or non-ferrous metal). If you melt it for the first time, it makes sense in the next preparation. It is necessary to clean the container, remove rust and debris, dust, rinse thoroughly, let dry, and only after that it can be used.

During cooking, remove floating slag - paint residues or contamination, they will significantly reduce the quality of the metal. After the metal has melted well, it needs to cool down a bit so that there is less splashing and it is more convenient to pour into molds. The latter should not be wet, so that the evaporating moisture does not create bubbles in the product.

Everyone knows how useful peas are, but not everyone can cook them deliciously. There are a huge number of recipes for soups, cereals and other dishes with this ingredient. But the main thing is to be able to soak it correctly. Without it, there is a chance to waste time and money.

What is the secret to soaking peas?

Peas, whole and split, are sold dried. It is almost completely free of moisture. If you start cooking it right away, it is difficult to calculate the cooking time and the required amount of liquid. If the product is pre-filled with water, it will cook several times faster, which will save time and resources.

At first glance, everything is obvious. Fill it with water and wait. But there are a number of features that must be taken into account:

be sure to sort and rinse in running water several times;
use only cold water, otherwise the product will turn sour;
soaking time for whole peas should not exceed 8 hours, split peas 3. If you keep it in water for too long, you can get the opposite effect. Peas will be firm even after long cooking;
minimum soaking time 1.5 hours for halves, 5 hours for whole;
the ratio of water is one to three. i.e. per 100 gr. beans 300 gr. water (maybe a little more);
do not add salt! You can salt peas only when the dish, in which it is almost ready.

If there is no time

There are situations when it was not possible to soak the peas in advance, or they simply forgot to do it. In this case, you can fill the product with water and add a teaspoon of baking soda. So it will swell and become soft much faster. In addition, after this not cunning manipulation, the product will be better absorbed.

But there is also a minus. Soda degrades the beneficial properties of peas. For example, it reduces the concentration of vitamin B1. So whether to add soda or not, everyone decides for himself. To avoid an unpleasant aftertaste, after such a soak, the product must be thoroughly washed.

Peas can not be soaked (peeled) if you cook it on low heat in a small amount of water. It sounds paradoxical, but the method really works. The only negative is that you need to constantly monitor the dish, stir and add boiling water as needed. If you wanted to cook soup in broth, then in this case, it is advisable to chop the meat (smoked meats, etc.) and stew separately in a pan along with carrots and onions. Meat, like salt, is added 10 minutes before removing from the stove.

With this method of cooking, which takes up to one and a half hours, the peas are soft, but not boiled soft.

Cooking peas in a slow cooker

Modern miracles of technology greatly simplify the life of housewives. If you are using a slow cooker, it is enough to soak whole peas for 2 hours. Shelled can be cooked immediately. If you are preparing soup in a pressure cooker, you can boil the peas for several minutes by turning on the appropriate program, and then add all the other products.

Helpful Hints:

split peas are faster and easier to cook;
before boiling, the beans can stick and even burn. Stir more often;
the longer the peas were stored, the slower it absorbs moisture;
if foam appears after soaking, the product is spoiled, overstayed or sour;
the hotter the room, the less you need to keep in the water;
peas are ready for cooking if their size has doubled;
if the grains are poured with water and placed in the refrigerator overnight, you can cook in the morning;
peas go great with smoked meat (fragrant chicken or loin will make pea soup one of your favorite dishes).

It doesn’t matter what exactly you are going to cook, the main thing is to do it with your soul, and then it will definitely turn out delicious. On our website you can order peas in bulk.
