Thank you for that Jack.At the moment I am just wondering what colour the Babyclay becomes after baking.The first lot of clay I got I made a mini baby Head,baked it and it is a nice baby colour.(lightish).Later I made arms/legs and baked them the same way and found that the colour of the baked clay was darker than the head.Thinking that it was me, I made and baked another set of arms/legs and again they are darker than the head.what am I doing wrong.The thickest part is 1/2inch.The only thing I can think of is that I am baking them for 15min and the head was done in ten minutes.(well, third time lucky)Thank you for the good luck thought Jack

Moonies are caused by very small air bubbles with water particles in them under the surface of all polymer clays. ProSculpt rarely has moonies because we mix unbleached titanium in the clay and that helps to camouflage the moonies. If you cure ProSculpt at 275 degrees for 10-15 minutes you shouldn't have cracks or moonies. As Chris mentioned, stretching polymer clay brings the bubbles to the surface of the clay and will definitely help to cause moonies. Allowing your clay to cure in the oven and then cool to room temperature will help to assure its strength. Good luck in your sculpting. Jack

Dee, I have been trying the technique you describe where you open the oven door a crack after the curing time. No cracks or moonies for me either, but I find that I have the moonies most of the time when I stretch the clay too much when working with it, mixing etc. And here I am not referring to Prosculpt, but another brand of clay that I sometimes use. I very rarely , if ever have moonies with Prosculpt. chris

Having read different Artists views on Baking the clay, one wonders whether they are all correct or not.I have always baked the same way for various clays. Wait till the oven gets to 130 then pop my sculpt in for the specific time and then turn off and wait till oven gets cold. Then remove the sculpt. I have recently tried it a bit differently with my last 2 babies in that, when baking time limit was up I would just open the oven door a tiny bit and put something in the door to stop it closing.( about 1.5 inch gap) Then leave it till cold. Still no cracks or moonies.Am I on the right track?
