This stamp is made for marking your ceramic pieces, polymer clay, and cold process soaps.
It’s got just the right hardness and depth to press into your clay without losing detail. Just a heads-up: these stamps aren’t made for use with ink.

BITERSWIT GUIDE: USING & CARING FOR YOUR STAMPS
Here’s our Biterswit guide with tips on how to take care of your stamps and how to use them like a pro.

HOW TO STAMP ON CLAY – Little Tips & Tricks :)
- Super easy! Your clay is ready to stamp when it’s still soft and shapeable—not too dry. It should be soft or at a leather-hard stage so the stamp can sink in nicely. You’ll figure out the sweet spot with a bit of trial and error depending on your clay type, moisture, and room conditions.
- Avoid stamping on material that’s too hard—it could break your stamp.
- Try out different levels of pressure until you find what works best with your clay. Since the stamp is transparent, you can peek from the side to see how deep it’s going.
- Bigger stamps need more pressure, so it can help to support your piece from underneath with something like a metal base, your hand, fingers—whatever works to keep it steady. Big stamps are great for flat objects like plates, trays, coasters, or thicker-edged pieces. For delicate pieces, we recommend using smaller stamps since they need less pressure.
- If the stamp sticks to the clay, a light dusting of cornstarch on the surface can work wonders to keep it from sticking.

HOW TO STAMP – TIPS & TRICKS
- Your soap is ready to stamp when it’s firm enough to cut—usually around 24 hours after making it. This depends on humidity and temperature, so check when you can unmold it.
- Once unmolded, cut it into bars.
- Spray the soap with 96º alcohol before stamping. It prevents the stamp from sticking. We’ve tried spraying the stamp too, but spraying the soap gives better results (and it’s easier!).
- Try different pressure levels to find what works best for your soap’s consistency. If it’s too dry, you may need to press a bit harder. Since the stamp is transparent, you can look from the side to check how deep it’s going.

OTHER WAYS TO USE YOUR STAMP
Your stamp isn’t just for ceramics! You can also use it on:
- Cold process Soaps (When they are soft)
- Polymer clay
- White air-dry clay
- Cookie dough
- And other similar materials

HOW TO CLEAN YOUR STAMP
If your stamp’s getting a bit clogged with clay and your impressions aren’t as sharp as they used to be, it’s cleaning time! :)
Here’s a short video that shows you how (we hope it helps!).
