What types of faux finishes are possible with polymer clays? The types of faux finishes are increasing constantly. Marbling is possible, wood like finishes, mokume gane, stone, turquoise, metallics, etc. Imitation turquoise can easily be created by mixing an appropriate turquoise color with two or more other colors. Create a bead shape, carve it slightly, then roll it in dirt -- yes dirt. After baking the bead will bear a very close resemblance to native turquoise, especially when strung on silver wire.
