Charcoal is a main fuel for my metal melting furnace. This time I want to share how I usually make it.
Step 1: Preparing Firewood and Starting a Fire
To make charcoal I use all the wood I have. No matter if it's dry or wet. I load firewood in steel containers, add some gasoline and start a fire.
Step 2: It's Time to Close Containers
After some time time (in my case it was approx 2.5 hours) it was time to close containers. No air should get inside!
Step 3: Got Perfect Charcoal
After 24 hours I opened containers. Only the upper layer of firewood didn't become charcoal. All other firewood became perfect charcoal. This quantity will be enough for 4-5 aluminum (brass, copper) melting in my smelting furnace.
