“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….”

“So excited that in my finale of glaze tests with the @ceramicmaterialsworkshop I was able to recreate one of my favorite glaze combos of all time! I’m so stoked to continue learning and can’t wait what information I get from the Crystalline series!”

“You both have totally changed my ceramics, I am having the best year ever! Best thing I have done in my career was to take your courses.”
– Ellen M., Advancing Glazes Student
“I am listening to your lecture in the car through traffic and it’s a different experience now that I understand what you are talking about and actually experienced it myself.”

This summer I took Matt and Rose Katz’s online glaze class @ceramicmaterialsworkshop. These little tiles are from one of the assignments. The class is pretty exciting if you want to dive into glaze chemistry with a hands on approach. At first the price of the class seemed like a hurdle. I also have had bad experiences with online classes and was pretty hesitant to take one again. This online class was REALLY different. I have to say it’s been totally worth it! Anyone who wants to build a solid ground in studio ceramics would benefit from this class. There’s some really cool information and research that you’ll want to understand, especially if you work at cone 6 like I do. I started out teaching myself glaze chemistry with some old books because I often like to do things the hard way by myself 😂 That was a really tedious approach and not something I expect many people to find appealing. It was sort of fun to remember the very few things I learned in high school about chemistry and I got a little bit out of that, but not enough to really understand what was going on with my glazes. The most exciting thing about the glaze class is that some of the concepts aren’t yet available in book form. Even if they were, I’m not sure I’d be able to pull all the information out there into a digestible form by myself. The class is also full of people from around the world and has become a community of sorts for people who are making their own glazes. A gift that continues even after class is over! I’ll be referencing this class and community for a long time. Thanks @ceramicmarerialsworkshop ! Ellen B. – Student

”After years of teaching ceramic materials courses in a traditional classroom lecture, Matt Katz developed and designed the Ceramic Materials Workshop specifically for online educational access. These innovative courses have proved highly successful; student evaluations consistently praised Matt for his knowledge of ceramic materials and their applications and applauded him for his concise and personable presentation of challenging technical content. The online format proved exceptionally conducive to robust group interaction and discussion. I highly recommend these classes.”

“…A palette of some very pretty nude tones from the results of my last @ceramicmaterialsworkshop lab. There is a load of titanium in the base glaze creating lots of interesting texture and phase separation…The next step is going through these again and selecting a few more to develop. CMW say they will change your practise forever and it’s definitely true! It was the best investment to learn the chemistry behind glazes. Highly recommended to any potters who want to deepen their glaze knowledge.”

“These past few years of exploring glazes felt like wandering around a strange city without a map. I bought glaze books that offered some great recipes, but I felt I was just sightseeing. Through thousands of tests, I gradually became familiar with various neighborhoods like Celadon and Iron Red. But what I really needed was a vantage point from which I could see where I was and how the various regions related to one another. Of course, such a “map” already exists- UMF and the Si/Al Stull Chart. While there are many books and websites that explain the basics of UMF, the explanations are often dry and technical. It wasn’t until I listened to Matt’s lectures and talks that I began to truly understand things. I now have a “map”, and my glazes have vastly improved.”

“I have been taking a couple of online glaze courses, and am really happy about them, and want to let people who are interested in glazes know about them. I think Ted Secombe said it best when he said, “I am not a chemist, I am a cook.” That probably describes most of us — we learn to add and subtract materials and we develop a collection of recipes that work for us. And this cooking is an incredible tool, because we develop a feel for what materials do, and we learn how to use our particular ones, which are often unlike ones with the same name. This course is about another tool, one which allows us to understand the structure of the glaze from the perspective of chemistry. It is taught by Matt Katz of Ceramic Materials Workshop, who also teaches glazes at Alfred University, a unique place, in that it is renown in both Ceramic Art and Ceramic Engineering. I think Matt is an exceptional teacher. He is able to explain things in a clear way and his enthusiasm is infectious. He really knows a lot. I have no way of quantifying this because I’m not there yet. But a lot. He has devoted his life to this. The videos are very enjoyable. So what am I learning? I learned how to calculate the Unity Molecular Formula for a glaze, learned how to use the automatic UMF Calculator that he provides, so that I don’t have to do that calculation too many times, but most of all, there is a chart that was developed by R.T Stull in 1912, and if you look at the UMF on this chart, you have a good idea what the glaze is going to do, and if that turns out to be something that you don’t want it to do, you have a path to nudge it in the correct direction. Part of the course is looking at glaze faults, and this has also been helpful with my stoneware glazes. How to look at the basic ingredients of a glaze, and see the relationships that need to exist to have a strong, functional glaze. There is much more than this. I’m just trying to give an overview.The courses I’m taking are “Glaze of our Lives,” (Understanding Glazes for the Beginner), and “Glazed and Confused,” (Understanding the Unity Molecular Formula).They are introductory courses but I’ve been making pots for almost 50 years, and there was a lot there for me.

“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!”
