Building a fusing kiln


#1

greetings from Alaska!

I’m building an indoor table top fusing kiln. I’m working with.999
Silver and Gold, and 0-1 Tool Steel. (maybe PMC) small scale.

I’m thinkin an adjustable box made of movable firebrick and ceramic
wool. ~12" x 12" outer dimension.

I want to fuel with propane and need suggestions for burners. I want
at least one overhead goosenecked fire pipe for preheating (pencil
torch on a heavy bendable wire)

I’m building modular charcoal and solderite surfaces as a fire
floor. What would be the best 'loose, granular, material to partially
bury.999 metals in, with an eye towards heat sink capability? sand,
charcoal, coke, coconut charcoal?

I’ll build an electrical ceramic heating plate (jecproducts) floor
later.

precision propane burner suggestions? how to accurately control gas
flow?

also, what are the possibilities for reading and controlling
temperature with this design?

I’m not running complicated heat treat recipes.

any comments/suggestions welcome. crazy (safe) ideas especially
welcome!

Jim
