On Fire!

Looking through the spy hole in the kiln door, the inside of the kiln is glowing red hot which means that the piece inside is almost melting!  Did I build it strong enough to withstand this extreme temperature? (which is completely necessary if it is also to cope with frost and snow in the winter) It has to shrink and start to melt without cracking or sagging. All i can do is trust my skill, cross my fingers and hope!
