Melting cast iron at home - Element Cube Collection (DIY)

We have reached the seventh cube for the element cube collection: Cast iron! Made from a pair of disc brakes, which was quite a challenge to get melted due to cast iron's high melting point.
As something new the cube is engraved using electro etching, where an electrolyte of vinegar and table salt is used. The power supply is set to 12V and draws around 500-1000 mA. Please remember good ventilation when doing this.

Using the strength of my brother is my favorite type of strength to use.

Thank you for this video. I was surprised by the time involved to melt the cast iron.

You can us yellow mustard too, works well to etch iron or steel. Just cut out a stencil smear a layer on and wait about 15 minutes for a dark etch.

I think the iron got hardened and more brittle after quenching, you should probably temper it before cutting

Would be great to be able to cast beds for machines like this.

You should try pouring it into a thin sheet and decarbonizing it to turn it into regular iron. I haven't seen anyone do this.

How did you make the steel melting stove and what do you use as fuel?

[@sunychristo5610]

What is the name of softens that you put on the melting cast

[@harlech2]

Does anyone know where can I find an iron foundry that could make a cast iron cauldron??

[@ReddyNaik-cf1uy]

How much time will taken melting iron bro

[@addictchris2503]

Bronze is not an element, but the cube is cool nonetheless :)

[@ebzerelmarov9785]

Hello. I ask you very much, can you help me?!
