Some of the companies listed below are sending me free samples to evaluate. I do not receive any financial compensation from them for writing about their mold compounds. I write because I am passionate about making jewelry molds and knowing the materials are part of that passion.
My mold compound comparison spread sheet contains data from the following companies:
Rio Grande http://www.riogrande.com/
Zero-D Products http://www.zerodproducts.com/ Manufacturers of the most dependable and consistent mold rubbers available today.
Castaldo http://www.castaldo.com/
Nicem, S.p.A http://www.nicem.it/ Slide show of some of their molds
