How hard is the clay when it is cured?
by P Smith
Your article is very interesting but I have a question. I have just 'cooked' my first batch of tiles but they still seem to have some bend in them after 'cooking' them twice. I must admit it has been hard to keep the oven at a steady 130oC (Sculpey Original)and sometimes it has gone lower and then a bit higher. (I bought an oven thermometer).
How hard is clay when it has been properly cured? Should it be as hard as china for example? Or does it have some give in it?
Thank you very much for your help.
