Agnes started pottery more than 20 years ago. What began with her first small pot on the potter’s wheel quickly grew into a deep passion for ceramics, glazes, and everything that goes along with them.
Over the years, she delved deeper and deeper into various techniques, materials, and, above all, glazes. In doing so, she regularly ran into the same problem: while there were beautiful products available, good and clear information on how to use them was not always easy to find.
Glazes and tools were purchased without knowing exactly what could be done with them, how best to use them, or what results could be expected.
That had to change.
With that in mind, Keramiek & Glazuur was born: a place where you can not only buy ceramics supplies, but where knowledge, guidance, and hands-on experience are just as important.
What began as a small online store has since grown into a specialty ceramics shop with an extensive selection of glazes, tools, and materials for both novice and experienced ceramic artists and potters in the Netherlands and other European countries.
Our guiding principle remains the same as it was when we first began:
A good product only becomes truly valuable when you know what to do with it.
That’s why we use and test many of our products ourselves, create samples and glaze combinations, and share our knowledge through our store, workshops, classes, demonstrations, social media, and online resources.
Agnes’s book was also published in 2026: “More Than Just a Jar of Glaze—Understand Ready-to-Use Brush Glazes and Discover Techniques for Your Ceramics.” In this book, she draws on her many years of practical experience with ready-to-use brush glazes and shows how you can better understand, combine, and apply glazes.
At Keramiek & Glazuur, we specialize primarily in ready-to-use ceramic glazes, glazing techniques, and ceramic tools.
We believe it’s important that a product isn’t just sitting on the shelf or in the online store, but that we can also explain how it works, what it’s used for, and what you need to keep in mind.
That is why we pay close attention to:
testing glazes and glaze combinations;
trying out new products and techniques;
clear and practical product information;
personal advice;
real-world examples;
workshops, classes, and demonstrations;
sharing inspiration and knowledge through our online channels.
We work with various well-known brands from Europe and the United States and are authorized dealers for brands such as AMACO, Coyote, Mayco, and Speedball, among others.
By working closely with manufacturers and suppliers, we stay up to date on new products, applications, and developments in the ceramics industry.
We supply not only individual ceramic artists and potters, but also professional ceramic artists, studios, schools, and stores in the Netherlands and other European countries.
At De Pottenbakster, various aspects of ceramics come together. Our studio, our store, our online store, and our warehouse work closely together.
This allows us not only to sell products, but also to actually use, test, demonstrate, and showcase them.
Our studio is where ceramics come to life in practice.
Here, we offer courses and workshops on pottery and glazing techniques, and we experiment with new materials, glazes, and techniques.
In the studio, you can see many examples of glazes and glaze combinations on different shapes and types of clay. This gives you a much better idea of what a glaze looks like than just from a photo or a color on a screen.
An important part of our studio is our extensive glaze display wall. Here you’ll find sample tiles representing a large portion of the glazes in our collection.
We also use these examples every day when advising clients.
Through keramiekenglazuur.nl, we offer an extensive selection of products for ceramic artists and potters.
But sometimes you want to see a glaze in person, compare different colors, hold a tool in your hand, or simply discuss which products are best suited for your work.
That’s why, in addition to our online store, we also have a brick-and-mortar studio shop.
Here you can browse products, get advice, and find inspiration from our many glaze samples.
We also try to share as much knowledge as possible online. We think it’s important that you not only see what you can buy, but also understand how to use a product.
Orders placed through the online store can also be picked up at our location.
The warehouse is located behind our online store.
This is where larger online store orders are collected, checked, carefully packaged, and shipped to customers in the Netherlands and other European countries every day.
A large portion of our ceramic products is sourced directly from manufacturers and suppliers. This includes large shipments from the United States.
By maintaining a large inventory of products from brands such as AMACO, Coyote, Mayco, Speedball, and other specialty ceramics brands, we are able to offer a wide range of products to both individual and business customers.
When new products arrive, we don’t just put them in the warehouse whenever possible. We want to get to know them, test them, and understand them first, so that we can actually tell our customers something about them.
Ceramics & Glaze is a division of De Pottenbakster BV.
Behind the online store, retail location, studio, and warehouse is a dedicated team that works together every day to ensure that everything runs smoothly.
Everyone within the company has their own responsibilities and areas of expertise. From product knowledge and workshops to customer service, marketing, order processing, and keeping track of thousands of products: together, we ensure that our customers not only receive the right materials, but can also count on excellent service and practical advice.
