Product Description Molding Paste dries to a hard, opaque film. Although still flexible, it is more rigid than the Gels. It holds stiff peaks to create a highly textured surface. Golden Gel Mediums offer a range in consistency from pourable to moldable with various levels of transparency and finish. Experimentation is recommended. They may be used to create glazes, extend paints, build texture, change finishes and work as gluing agent for collages.
