So I brought some experiments with the new Studio by Sculpey clay to the January Guild meeting. My initial evaluation was that it was very strong after curing, and I demonstrated the flexible strength of the background behind this little birdie.
Two weeks later, Jeanne Dumond from the Columbus Guild posted at PCC that her leaves made with SBS that were initially strong all broke. Trina Williams had a similar experience. And the background on my little piece in the picture easily fractured into bits.
Things that broke were cured properly by experienced clayers and were the thickness of the widest setting of the PM or less. My thicker tiles (3/8ths of an inch) remain strong. The beads are ok too, but it was pretty hard to make beads with this clay anyway.
So plan your projects accordingly or hold off til more post marketing experience can better clarify how this clay behaves.
