Review on Clear Silicone Mold Making Kit for Resin Molds - Miraclekoo 7 oz Liquid Silicone Rubber, DIY Manual Silicone Molds Making by Michelle Moore

I'm interested in new silicone casting and didn't know that sulfur in clay affects silicon and you need to use sulphur-free clay. The kit contains less volume than I was hoping for at 7 oz. won't go far. I used Crayola modeling clay to add dimension to the container. Where the clay was in contact with the grout, the silicone surface will remain tacky after a week. That annoys me, but if you want to use a clay model as a template, I don't think that's possible.
