Do you already have some basic knowledge of glazing? Are terms like flux, stabilizer, and melting point modifier familiar to you? Have you taken a basic glazing course but are eager to learn more? Then this multi-day workshop, which combines a lot of theory with practical experience in the form of a personal glazing project, is definitely for you!
On the first day, you will learn everything about the Seger Formula, also known as UMF. What is this formula, why is it useful, and most importantly, how do you actually calculate it? Nowadays, it’s all ready made available on websites like Glazy.org, but it's still valuable to do it yourself at least once. This way, you’ll understand where those numbers come from and be able to interpret and comprehend them much better. You’ll receive all the explanations you need, and then we’ll dive into exercises. Don’t worry, you can use a calculator.
In the afternoon, we’ll start working on your own glazing projects. You will describe your project in advance using a form I’ll send you. This allows me to prepare and help shape your glazing project. If you don’t have your own project, you will work with someone else.
On the second day, we will review, analyze, and improve your own glaze recipes using Glazy.org. We’ll explore the Stull Map, which is the chart you see on Glazy but might not fully understand yet. We’ll also examine silica/alumina and flux ratios and learn what they mean.
With the theory you’ve learned, we’ll delve into glaze stability, and matte and glossy glazes. We’ll use the software to improve your recipes, at least in theory. Then we’ll practically apply this knowledge as we continue to work on our projects.
The samples will be fired and discussed on the final day (evening). We’ll review each other’s samples and discuss any improvements so you can continue working on them at home.
Out and about with Steger and Stull - Advanced glaze workshop
This course is suitable for anyone who already has some experience with glaze theory. You should be familiar with the basic components of a glaze, such as glass formers, stabilizers, and fluxes. You should also be knowledgeable about raw materials like quartz and feldspar. You may have already taken a glaze course or explored the topic online and in books.
The course is limited to a maximum of 12 participants. Personal guidance will be provided for each glaze project. You can work individually or in groups.
