I'm about to put a clay order in and I'm reading about paper clay at Axner and Laguna websites right now.
I've never had any experience with the stuff...
I'm tempted to try it for my large (^6-7) platters and maybe some saggar pieces.
Looks like a very forgiving material, you can throw it, handbuild, everything according to them.
It seems most attractive due to what it says about 'forced drying' and lack of warpage since my studio is outdoors in the desert. Timing is everything outside.
