Have several, use from ceramics and pottery, wax burnout, gold and silver casting, glass melting and slumping, plus heat treating, so far only knives and weapon parts. Both table top models will hit 2600 and up. the stackable octagon ones commonly seen in ceramic shops will also and all of my large kilns are equipped with kiln sitters for auto shutoff. I have experimented with wax molding a custom 20 prop then casting in bronze, still works but I need to learn a little more about prop metals, I am leary of thinning the blades too much.
