If you didn’t know, Ceramic Materials Workshop is a small business.  Our mission is to provide our community with a solid understanding of their glazes and clay to make your studios the best that they can be.  In order to do that, we do all of our testing, research, editing and production in house.  If you find our content helpful, please consider supporting our mission by taking some of our online courses or supporting us via our Patreon.  Our team thanks you for your consideration!

Commercial Clay Body Profile Testing
Over the past several years, the CMW team has collected and tested scores of commercially available clay bodies.  The results are meant to help our students understand how these clay bodies perform to make their studios the best that they can be. Click below button to find results of the bodies that have been tested to date. We plan to add additional profiles as we continue to test additional clay bodies.
CMW UMF Calculators
UMF glaze calculators are designed to assist potters in formulating glazes with specific surfaces and textures in mind. At their core, these calculators utilize the concept of Unity Molecular Formula, which represents the molecular ratios of the materials in the glaze. By inputting the desired materials and their respective proportions, you can generate custom recipes that perfectly align with your artistic vision.
