Soapy Clay Recipe

7850-Soapy Clay Recipe - no cook cold porcelain clay

Soapy clay recipe is a no cook cold porcelain clay suitable for miniature fruits, flowers and other small objects. It will dry hard with smooth finish. 

I like this clay because it smells good. Some of you may ask, why we use soap. Well, beside for the fragrance the soap is actually somewhat preserve the clay. It keeps the clay fresh for few days.

But if the humidity level in your place is high, the clay will still be moldy if you don't keep it in the fridge.

Honestly, this clay is good if you use it all within 2 or 3 days. So, make a small batch - just enough for your crafts on the day you make them.

By the way, even though we use soap, you can't use it back as soap after you mix it with flour :)
