I'm embarking on a new adventure to learn more about metal casting. One of the key pieces of equipment is a furnace for de-waxing or de-molding, which we build in this video. Below are some links to the products we used in the video

RS PRO Flame Retardant Superwool 607 Fibre Thermal Insulating Sheet, 2.4m x 610mm x 38mm
• Superwool 607 thermal insulation sheet
• Flame-retardant
• Thermal shock resistant

We build our own propane torch due to time constraints however I'd recommend buying one (as it's cheaper than buying the parts)

We used 2x triple-ring burners as the primary heat source. Ultimately we turned off the outside ring (effectively making it a 2 ring burner) because there was more than enough heat output.

For the propane regulator, a regular BBQ-style regulator won't provide enough gas to operate the furnace (most have an inbuild safety feature that limits gas flow) Heres a link to a quality unrestricted propane regulator: https://amzn.to/3HjRU1I
