Veel keramiekstempels worden gemaakt van acryl of kunststof. Hoewel deze stempels vaak goedkoper zijn, kiezen veel professionele keramisten uiteindelijk voor een keramiekstempel van massief messing.
Sharper, More Detailed Impressions
Solid brass allows fine lines, small lettering, and intricate maker’s marks to be engraved with exceptional precision.
Built to Last
Precision-machined from solid brass, our pottery stamps are highly durable and designed to withstand years of regular use.
Perfect for the Pottery Studio
Brass is naturally resistant to moisture and the demanding conditions of everyday studio use, requiring very little maintenance.
Not every potter or ceramic artist has a professionally designed logo, and that’s absolutely fine. We can create a custom pottery stamp from much more than finished artwork.

For the fastest turnaround, we recommend uploading your artwork in one of the following file formats:
Not every design is immediately suitable for creating crisp impressions in clay. That’s why we personally review every order and, where necessary, make small adjustments to optimise your artwork for the best possible result.
Only have a photo of a signature, sketch, or maker’s mark? That’s no problem. In most cases, we can still transform it into a high-quality custom pottery stamp.
A logo that looks perfect on screen won’t always produce the best impression in clay. During stamping, drying, and firing, clay naturally changes shape and shrinks. As a result, very fine details can become less visible or even fill in completely.
Fortunately, this is easy to avoid. By keeping a few key design considerations in mind, you can ensure your pottery stamp produces crisp, clear impressions every time.
Every logo, signature, and maker’s mark is carefully reviewed before we begin manufacturing your pottery stamp. If we believe a design may not produce the best possible impression in clay, we’ll let you know before production starts.
Where necessary, we’ll recommend small adjustments to improve the final result. That way, you can be confident your pottery stamp will leave crisp, clean, and well-defined impressions every time.
Choosing the right size depends on your design and how you intend to use your pottery stamp. A typical maker’s mark is usually between 10 mm and 25 mm, while more detailed logos often require a larger stamp to ensure every line and detail is reproduced clearly.
Use our size guide to find the most suitable option. Each stamp size is shown alongside a standard bank card, making it easy to visualise the final dimensions.
Unless you specify otherwise in your order notes, we’ll scale your uploaded logo or artwork to the largest size possible within your chosen stamp dimensions, ensuring the best possible impression.
Our pottery stamps are specifically designed for use with clay, ceramics, and porcelain.
Simply press the stamp into soft or leather-hard clay to create a crisp impression of your logo, maker’s mark, or signature. Once the piece has been fired, the impression becomes a permanent part of your creation.
Whether you create mugs, bowls, plates, vases, or sculptures, a custom pottery stamp adds a professional, distinctive finish that makes your work instantly recognisable.

Every design is personally reviewed before production. If any adjustments are needed to achieve the best possible impression in clay, we’ll optimise your artwork and discuss any recommendations with you before we begin manufacturing.
