Hi Ann

I am a PMC tutor and also have Art Clay Level 1 certification. When I'm teaching I do tell my students about torch firing versus kiln firing. On the intro class we torch fire pieces so that students can see how it's done because its the way most people start (especially given the cost of a kiln!), but as the others have said, kiln firing longer and hotter than the instructions state gives you a stronger finished piece.

For me PMC is a lot softer than Art Clay, yes you can condition Art Clay with water to soften it but thats an extra thing to do - I'd rather get on with making!! I also find PMC has more elasticity which I prefer. I think using a pack of each brand and seeing which you prefer is definitely the way to go - Coke & Pepsi!!
