Understanding Glazes
Learning why your glazes work and don’t work, is the most important step in taking control of your studio.
Course Overview
Understanding Glazes Online is a course focused on the science behind glazes. No more myths and legends about how glazes work, only facts and science. The course provides information and science to help everyone utilize glazes in ways that will help them take control of their materials and make their studios the best they can be.
This course aims to develop a basic understanding of the following: 1) ceramic materials and their chemistry, origins, properties, and functions; 2) the tenants of heat and temperature as related to ceramic performance; 3) glaze formulas, analysis, and performance; 4) glaze flaws, their identification, and corrections; and 5) the function of ceramic oxides and color.
This is the same course that Matt Katz has been teaching for years at world class institutions, including The New York State College of Ceramics at Alfred University, Rhode Island School of Design and Harvard University.

Course Reviews
What Students are Saying
★★★★★
Just so you know, after more than 50 of making pots on and off, I’m setting up a new studio to make truly durable and pleasing ware for use in the home. I was totally at sea as to finding suitable clay and glazes till I found CMW. CMW pulled my bacon out of the fire big time! Now I am confident that I will have the knowledge I need to accomplish my goal. I’m also really interested in chemistry now, which I could never have imagined! You guys are totally the BOMB!!! Kudos!

“I just wanted to feed back how much I enjoyed this course. I now feel so much more confident in my knowledge and I’m already seeing the benefits it has brought. Matt has a great teaching style, I like that he repeats key information throughout the lectures to help embed the knowledge but that he will also tell you a bit more information about something as he is introducing it but just as you think your brain is about to go into overload he says “but we’ll talk more about that later”. It is a really good tool as it contextualises the thing you are learning about but then you immediately relax and just take in the info that he wants you to know in that particular lecture. The hangouts were excellent too and again, Matt was generous with his knowledge and super patient….” – Susan F. – January 2023 Understanding Glazes student

Hey Matt – I just wanna thank you and Rose again for teaching, in a really enjoyable way, the science behind glazes.I would’ve never imagined how cool chemistry could be and CMW’s workshops will change your studio forever” is nothing short of the absolute truth. Wish you guys a wonderful holiday and I’ll see you later!” Giuliano R. – Student – Dec 2021

…today one of my regular customers said, “ I went to a pottery show – and I can honestly say your glazes are above and beyond anything we saw there.” Very cool that education and work pays off.””

Frequently Asked Questions
Answers to Your Most Pressing Questions
What experience level is this class for?
Our classes are designed for makers of all levels. We’ve had professionals with 50 years of experience and we’ve had folks take our classes after having one studio class at their local community college. Everyone comes out truly understanding glazes.
Are you going to talk about…
Let me stop you there. We are going to talk about EVERYTHING.
Temperatures? Yes? Atmosphere? You better believe it. Materials? No way around it. At the end of this course, you will have a thorough understanding of ALL aspects of clays.
Why should I take this class?
I’ve got books. Books are great, but books are a supplement and a reference in education. The reason why school is still lecture classes, is because audio/visual learning is still the most powerful educational tool.
When I first started studying glazes I got a book, and I read every word…and I understood about 1% of it. The experience of listening and looking helps us to truly UNDERSTAND a subject.
I work at temperature X, is this class relevant to me?
Yes, we talk about glazes as a whole. All firing temperatures are interrelated. We’ll teach you all of the how’s and why’s of all glazes.
