A Step By Step Guide on How to Melt Metal

by Tyron

Before melting metal, you must first understand that heat application is a necessity. You can either use a foundry such as a metal melting furnace or a torch to achieve this. If you use a foundry, rest assured that the metal can turn into a liquid in split seconds while you make it into any kind of shape you prefer. Torch, on the other hand, allows you to cut the metal into different shapes after melting through the metal. One thing is certain in the end – that you can successfully melt metals using either of the two aforementioned options.

In this piece, you will find out a step-by-step guide on how to effectively melt metal:

How to melt metal

As a first-timer, here’s an easy way that you can melt metal in the convenience of your home!

Step 1

You can make use of a steel bucket, preferably one that’s no longer in use. Create a pipe hole. The essence of the pipe hole is for the furnace to get supplies with adequate air. Also, create more holes close to the middle of the pot lid that will cover the furnace. This helps the gases to circulate better.

Step 2

Pack enough bricks and set them up. The bricks will serve as an external wall for your furnace. They will work to stabilize temperature and also protect the furnace. Unlike the crucible and every other object around, they won’t be too hot. If the bucket comes with no bottom, it’s more reason why you should consider using these bricks.

Step 3

Find a can or something else suitable to create a crucible. Ensure that the can you’re using us purely fit for this purpose.

Step 4 – this is the point where you create a blower. In some cases, people make use of a spoilt vacuum cleaner. This will suck up air and also blow it. Other people may also consider using a dryer but the old vacuum cleaner is seen as a better option (even though it may be too strong for a small furnace).

Step 5

To make fuel, you can use charcoal. This can be gotten from firewood as it’s the basic raw material. While melting the metal, you can add smaller sizes of coal. Coal is needed at some point because it burns better than regular charcoal. It boosts the temperature higher and allows a faster melting process.

Step 6

Finally, add the aluminum into the fire and heat it until it’s melted completely. The heat should be frequently increased. This is to ensure that no solid piece of aluminum is found in the crucible.

The process of melting metal can take between some minutes to hours; it all depends on the particular metal involved, its thickness/quantity, and the high the heat of your foundry is.


And that’s it! When the melting process is completed, the metal tends to turn into cherry red in some seconds. You may also find traces of impurities that are probably burning off.
