How to make professional jewelry rubber mold

In order to create rubber mold, we use silver master mold as a main form. The make of rubber is Castaldo. By placing the actual master mold in the raw rubber and covering it with layers of rubber, we place it in a vulcanization machine. We heat the rubber at 375 degrees for 30 minutes.
