Heather, Thank you for helping. I have some pieces that I assume are completely dry. Some areas of the pieces dried lighter than other areas, but it is mostly a gray color. I think I'll paint them since they have dried for a few days now. I need to buy enamel paint. I think it will give a more kiln fired pottery look. Thank you for your reply.

Note from Peter (admin)
Have a look also at the air drying clay section of this site - -go to http://www.figurines-sculpture.com/cold-porcelain.html or you can access it from the 'How To Sculpt' section. There is a lot of good information on air drying clays there too. Thanks

Efa Plast Classic by: Heather C
The only air drying clay I have tried was called Efa Plast Classic which came in a small hobby shop style pack and the instructions were that it dries in 24 hours and can be sanded etc and painted.
I assumed at the time that air drying clays did not need firing but did not understand how they worked without having some sort of ingredient that dried like glue does so, I have to admit I only did a small test with this clay, but took the piece and fired it in my kiln to about 1050 deg C and it looked the same as it did before it went in. I wonder if these can be wetted again if they dry too much as the bag has been sitting in a drawer now for about 3 years and although soft is much to dry to work now. But if they can be re-wetted does this mean any non-fired piece will fall apart unless varnished? regards Heather
