Kaowool Furnace Build 

In this video, I take you through the process of building my new furnace from scratch. I chose a kaowool furnace because they are very simple to build and very lightweight. Total cost was about $390, and $300 of that was in the custom welding. So if you know how to weld, this furnace is incredibly cheap to build.
This furnace is INCREDIBLY well-insulated. After the first use seen in the video, it was still too hot to touch the interior after FOUR HOURS! The exterior was just warm. It also heated up to aluminum melting temperature very quickly. I'm very satisfied with how it came out.
The mason jar mixing system was inspired by ‪@PaulsGarage‬.
