polymer clay faq
polymer clay is a sculptable material based on the polymer polyvinyl chloride and liquid plasticizers . it actually does not contain any clay minerals and is only called clay since its textile properties resemble clay. polymer clays are cured in a standard home oven at temperatures ranging from 265-275`F for approximately 15 minutes per 1/4 inch of clay. no shrinkage or color change occurs during the curing process. polymer clay can be colored using a variety of media such as:
- paint
- ink
- colored pencil
- chalk
- mica powder
- metal leaf
- glitter
- embossing powder
currently there are quite a few options out there as far as your choice regarding which brand of clay to choose. each brand has its strengths and purposes depending on the project at hand. all brands have a large assortment of colors and there is always the option of blending colors or adding color using an additional media (my personal favorite). below are the brands of clay that i use along with my observations regarding the particular brand.
