This is the best tutorial I have seen on how to make cold porcelain clay for sculpting, stamping, etc.. the video is approximately 2 1/2 mins long and will help show you how to mix your ingredients (corn starch, olive oil, glue, vinegar, and body lotion) to make a study clay - air dries with no no cracks!
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.
