In today’s video we’re super-sizing the trashcan foundry into a giant garbage can kiln!This is an overall view of my furnace. As you can see it is made from a steel garbage can.

Any 5-7 gallon metal container will do the job.This is a 6 gallon trash can bought at the hardware store.Furnaces shouldn’t be significantly larger than the material they are trying to melt- a greater volume will take more time and fuel to reach working temperature.
The “King of Random“, as Grant Thompson (previously) is known, recently shared a video on how to make a simple and inexpensive mini metal foundry for melting pop cans and casting aluminum.
Metal foundries can reach temperatures in excess of 1,000ºC, which is well above the melting point of hobbyists. This project should only be attempted with adequate knowledge and training, proper protective safety gear, and in a fire resistant area with adequate ventilation.
