Cold porcelain! The perfect homemade clay? You betcha! This week I finally took the time to fully develop my cold porcelain recipe, and I am so pleased with the results! After searching high and low for a recipe that was firm enough for what I was wanting, I decided to just apply some chemistry knowledge and work it out for myself. It was a really fun process, and I ended up with a beautiful clay that turns out perfectly every time and can be scaled up or down with ease.
