What is Polymer Clay?
Click here for parts list and how-to tips to make these hair sticks. Polymer clay is a manmade, non-toxic plastic-based alternative to natural clay. Its only real similarity to natural clay is that it is shaped while soft and then heated for hardening. Owning a kiln is not necessary for polymer-clay work, since the temperatures needed to bake it are easily achieved in a home oven (265° to 275° Fahrenheit).

Each polymer-clay brand is made with its own "recipe," using various resins, plasticizers and other secret ingredients, each optimized for a different usage. You may end up choosing one brand for your sculptures or free-form jewelry, and another brand for millefiori cane work.

Although different brands don't guarantee they will mix together exactly the way you expect, many people have successfully mixed brands for desired colors, textures or consistencies.

Brands & Styles

Click here to buy polymer clay. Kato PolyClay™ is the polymer clay Rings & Things sells because it offers superior working properties! It's easy to condition, doesn't crumble and doesn't get sticky even after continuous handling. Plus, Kato offers Liquid Polyclay™, which works as a clay extender, softener, adhesive and finishing coat. Kato liquid clear medium allows you to do photo-transfers, create complex grouting effects and make colorful glazes that bake and bond to the clay.

Other major brands of polymer clay include Sculpey III® (a soft clay), Premo! Sculpey® (stiffer than Sculpey III, but softer than FIMO®), FIMO (a stiff clay), Cernit and Makins Air-Dry Clay.

Generally speaking, softer polymer clays are good for projects that don't involve extensive manipulations. They start out easy to work with, but if you make complex canes, your colors and shapes can start to blend together more than you might want.

Stiffer polymer clays may start out crumbly when cold, but they manipulate well in the long run. You can put a few colors in your pocket for a while to warm them before opening the packages. To warm polymer clay in cold weather, you can point a desk lamp at your clay, or place your clay on a heating pad that's set on its lowest setting. No matter what method you use, be careful not to overheat the clay, or it will start to bake.

If you live in a cold climate, you may also want to heat your work surface before you start working. Some people have said a blow dryer works well. However, use caution when using a blow dryer (or anything else) for a use other than the manufacturer intended.

If you work with polymer clays as a hobby, you can use your regular home oven. Toaster ovens are not recommended, because they don't heat as consistently. If you seriously delve into polymer clays, you will probably want to invest in a second oven, for convenience if not for potential long-term health reasons. All of these polymer clays are non-toxic and well-tested, but it somehow seems foolish to be cooking food in the same oven in which you are daily cooking plastic ...

Tools & How-To Tips

Polymer-clay tools: Choose from several useful and fun polymer-clay tools to expand your design possibilities. We offer everything from basics like blades, rollers and modeling tools, to texture plates, extruders (Klay guns), pattern cutters and molding compound!
For general information about what types of polymer clay work best for what type of designs, see "Brands & Styles" above.

Tips and how-to hints for working with polymer clay:
  • Work on paper to minimize handling and fingerprints.
  • Buy ceramic tile from your local building supply to bake pieces on.
  • To tint clay, use non-toxic blushes and eye shadows.
  • Adding gold should make colors warmer; silver adds a cool tone.
  • Try conditioning your clay in a pasta machine. This works especially well for FIMO, which can become exhausting to hand condition.
  • Sand before you glaze, or buff with 400 grit and then 600 grit wet/dry sandpaper under running water.

Polymer-Clay Resources

Polymer Clay Info Links — Updated 2010
  • PC Polyzine offers some great "how-to" articles.
  • Glass Attic provides an "encyclopedia" of information about polymer clay with approximately 90 categories of information (in over 1700 pages) relating to common polymer-clay techniques, including how to avoid problems (or fix them), what kinds of tools might be helpful, etc.
Polymer Clay Guilds Click here to visit the International Polymer Clay Association (formerly the National Polymer Clay Guild). The International Polymer Clay Association (IPCA), formerly the National Polymer clay Guild (NPCG), is a great international source for the latest information on various forms of polyform clay (FIMO, Premo, SculpeyFlex, Cernit, etc.). As of 2008, yearly dues were $30, and included a subscription to their fact filled newsletter, the POLYinforMER. Visit them online, or write to them at:
