Polymer clay Brands and thier properties

Some rules of thumb about polymer clay.

  • Most clays need to be baked for 20 min at 275 per 1/4 inch of thickness.
  • The softer/stickier the clay, the less you should count on it for strength.  This stuff, however, is good for bulking, and is cheaper.
  • Most clays will benefit in strength if you bake them longer
  • Clay does have a shelf life, and more likely to have problems when it is older
  • Polymer clay doesn’t go bad.  It will take longer to get conditioned, and possibly loses some of its strength, and may be more likely to crack and moon
  • Having a dedicated food processor/coffee grinder for this clay will make your life easier for conditioning purposes.
  • A toaster oven will work as well as an oven for curing polymer clay.
  • Polymer clay is not toxic, but you still might consider using a toaster oven just for your clay.
  • The softer the clay, the more the colors will bleed.  They have more conditioning oils in them which tends to mix with nearby colors.

  • These are what I consider FUN clays.  They aren’t for serious work but have unique properties.

Translucent Clays

Translucent clay is usually a very very thinned down polymer clay.  It’s consistancy is that of a thick soup (usually) and is fairly translucent.  They all claim that they are translucent, but once cured, they aren’t really.  This clay has some interesting uses, from transferring images (lazer printer) onto other things, to making thin membranes (think fairy wings) to smoothing out and finishing or sealing a sculpture.  Because this is a thinned out clay you can also use it to soften up a harder or older clay.  Another important reason it exists is as a glue for other polymer clays.  If you have two things which need to be attached securely, you might add a small dob of this stuff and then cure as per normal.
