Thank you for the Welcome...
What's up next? Well, I've just acquired all the materials I'll need to mold a small refractory furnace using a half sized oil drum, refractory cement, and I'm going to try and cut a lot of the weight by adding pearlite to the mix. I shouldn't suffer any thermal quality by using the pearlite, in fact I'll probably gain more insulation by using it. I've made small coffee can forges using it and plaster of paris to line the forge and could easily bring small pieces of steel to welding temp, yet still be able to handle the outside of the can. Probably gonna start on it this coming Sunday after breakfast.
