I got some Make A Mold about 3 years ago, maybe 4. Like alot of things it has state with my supplies and I came around it this weekend. What is the shelf life on it? Is there a way to tell if it is still good or not?

Most silicone mold making products have a shelf life of 6 months. MYOM silicones are good for a year. As these products age, they lose their reactivity. To see if your products are still good, combine them and place them in a warm oven set at 120 degrees. If it does not cure in the oven, it never will.

Hope This Helps,

Thank you. I'll hve to try it out sometime soon and see if it work.
