How To: Rubber Stamp on Baked Polymer Clay

We’ve all heard about how rubber stamps can be combined with unbaked polymer clay. But even when the clay is baked, there are still ways to combine rubber stamps with it. The effects between unbaked polymer clay with rubber stamps are different compared to baked polymer clay with rubber stamps. Naturally, this means a different method of stamping when using baked polymer clay:

Rubber Stamp on Baked Polymer Clay

The curious thing about stamping on baked polymer clay is that a certain amount of care should be given since it’s closer to resembling stamping on paper. You will only be able to get clean and firm impressions with your rubber stamps if you keep your rocking to a minimum. Especially when stamping with ink since it has a tendency to smear upon rocking. For stamping with baked polymer clay, you can choose to either stamp it with ink, embossing powder or both.

Stamping with Ink

You can combine rubber stamps, ink and baked clay. If you use materials like Stazon Ink or any permanent ink, they can have the potential to be waterproof. But when exposed to alcohol, these inks will still run. You can take precautions to heat set the inks in the oven, with reference and advice from professionals, to solve that problem.


Depending on the ink you use, certain types of ink like pigment ink, do not dry completely while on polymer clay so the alternative resort is to mix them with embossing powder and set with heating tools. This will result in raised images on your baked clay, so be prepared for that and make it work to your advantage with design.

As a general tip, you can consider working on a surface that is to be baked on if you plan to make deep rubber stamp impressions. It can be tricky transferring sheets but if you take great care on doing so, you can pull off quite a vast array of beautiful designs. Also take note that you can cut out stamped elements if you intend to do so, with craft knives before or after baking. But a good recommendation would be to do so before baking the clay since it’s a lot easier to smooth the edges of unbaked clay than baked clay.

Another factor to keep in mind is that embossing is generally recommended after you have finished baking the polymer clay since embossing powder can cling onto unbaked polymer clay and achieving a clean embossed image would be immensely difficult when that happens.

Polymer clay can be combined with different products and substances before and after baking, so be sure to do so and experiment around with different crafting ideas!
