Stamping on Polymer


Rubber Stamp Tapestry peg stamps are small and work with polymer clay in ways larger, traditional stamps just can’t. Whether you’re making jewelry or items for your home, Rubber Stamp Tapestry peg stamps and polymer clay work very well together.


Special Instructions for Stamping Polymer Clay


1. Choose Your Polymer Clay
Any brand of polymer clay can be used for stamping. There are differences between brands which can affect malleability, durability and longevity after baking, as well as impression permanence (when dry stamping into clay), so you’ll need to experiment to see which works best for you.

2. Choose Your Stamping Technique
There are a myriad of stamping techniques from which to choose. We will look at three simple techniques and each will require different supplies.

  • Dry stamping (without ink) on unbaked clay.
  • Stamping on unbaked clay.
  • Stamping on baked clay.

3. Choose Your Ink
We recommend using a solvent ink like Staz-on™. Solvent inks are formulated for nonporous surfaces and are sure to give good results.

4. Condition the Clay
Polymer clay must be conditioned before use to make it malleable and thoroughly incorporate the plasticizers. You’ll want to condition the clay until it is workable. Depending on the brand, this may mean simply working it with your hands, using a pasta machine, or even a food processor. Warm clay will be easier to condition and the best way to warm it is with body heat, anything hotter and the clay may begin to cure. If your clay requires the use of a pasta machine or food processor, be sure to only use it for the purpose of polymer clay. All equipment used for polymer clay needs to be dedicated to that purpose.

5. Stamp
Once your clay is workable, you can roll it into the thickness that you desire. The thickness will affect bake time as well as the durability of the piece after it’s baked. If your piece is too thick it will require a longer bake time and if it’s too think it may be brittle and break after baking. Refer to the manufacturers instructions for more information.

  • Dry Stamping on Unbaked Clay - spritz clay with water, which will act as a release agent. Gently press the stamp into the clay with steady pressure, like
  • stamping on paper. If you press too deeply, you’ll create a moon around the image.

6. Clean Stamps
When dry stamping, remove any clay in the crevices of the stamp with a small ball of clay, dabbing the stamp lightly to adhere stuck clay. Then, thoroughly clean the stamp with a stamp cleaner. If using ink, you’ll want to clean between ink colors and after the final stamping. Solvent inks may color the rubber and cleaning early will minimize this.

Upholstery fabric, denim, or any coarse fabric combined with the cleaning solution makes a great stamp cleaner. Use a toothbrush to clean recessed areas of the stamp. To protect your stamps, clean them before storing.
