Orton Cones - Pyrometric Cones for Monitoring Ceramic Kiln Firings - Cone 04 (1 Pkg/50)

Are cone 03, 02, 01, 1, 2, 3 available?

Are they 05?

are cone 5 cones available? i can't seem to find them

Is it normal for cones to be stuck together and have to be broken apart? I have only bought like 4 other boxes before but never stuck together?
