I’ve been looking into mold releases for use in small and very small scale SilverCrete applications. Mold release is simply a substance that prevents the mold from unintentionally becoming part of the finished piece. Without a release, you could potentially have to destroy either the mold or the molded item to separate the two. The idea is pretty simple, don’t let them stick together. This is really only important if you’re using anything other than silicone for your mold although you’ll probably want to use a release after the second use of the mold.
Vegetable Oil Mold Release
In the past, cooking oil resulted in adequate results. However, as the molded piece gets smaller, there is less material to “absorb” all that oil and could result in quality problems, depending on your mold. I am currently experimenting with a release that I am very excited about. It won’t be finished for a few months so using the above mentioned releases will be just fine. I’m really hoping that my experiments will come up with a product that is more useful for ALL mold types and is consistent. I’ll keep you posted.
