<<Pyrometric cones are basically pyrmidal shaped clays made to bend/melt at exact temperatures. >>

I should note additionally regarding the proper melting of cones, large cones(about 3" long are calibrated to melt at I believe a rise of 650°/ hour. Not certain on that, I'll have to check. snamm cones(about 1 1/2", I don't remember. I use large cones for glaze/gas firing, small cones for the electric kiln.
