An Introduction to Glaze Testing Part 1

Welcome to The Potter’s Round Table, the topic today is An Introduction to Glaze Testing - Part 1.
One way to learn how to fix problems with your glaze is to understand what each ingredient does and how it affects the final glaze. This mini-series on glaze testing will explore a simple glaze recipe and how to determine what part each ingredient in the glaze plays in the fired glaze result. Through a series of changes to the glaze recipe, focused on a single ingredient, we fire the different glazes and inspect the result in a process that can be repeated on any glaze recipe.
At the end of the presentation there is a short Q&A session.
The Potters’ Round Table is a production of Washington Street Studios. As a result of the pandemic the Round Table is hosted as a YouTube livestream event and then edited to be added to our video library.

At Washington Street Studios, we believe the sharing of creative energy and knowledge will improve the quality of our art and increase the appreciation of art within our community. We are striving to create an environment where the arts are shared and appreciated. We want to grow as a family of artists and contribute to our community.

I just wanted to thank you for sharing your boundless knowledge in this glaze testing video, in the videos on firing a small gas kiln, & all the others that you have done. Your lecture style is so concise, & packed with your practical, experiential information & tips; Please, DON'T apologize for putting "too much information in such a short video"; This Is one of the best lectures I have attended on any subject in my entire life! 20 years ago, I started reading about glazes through independent study -- trying to gain an understanding of glaze composition, etc; it is only NOW in 2021 that I am in a position to actually do it, and I am gearing up to fire my Olympic 1827G (Which I've had for 20 years and fired only 4 times). Anything I read back then was sort of vague and short on specifics of procedures; the internet wasn't what it is now! Here I am 20 years later -- I am Re-reading books on glazes and kiln firing, & re-learning the things I had tried to study so long ago. You gave such a great overview that it made the topic come to life, and I was able to retain a lot of it without even taking my notes yet. I will re-watch, this, and your other firing videos and I am going forward with confidence and excitement about the whole process, instead of feeling like I am groping around in the dark unsure of myself. I come away with actively remembering to give it a try, pay attention and observe, and really think about what I'm seeing! Thank you so much for that!

“You put the sticker on your forehead “ that gave me a good laugh 😂😂👍

[jimeortega]

by any chance, you guys have a formula for the base glaze conversion quantities?

[riverriverchang]

you're doing charity putting these info online for free

I am not following. By reducing by nearly 1/2 of the ingredients that were not doubled, haven't you made the doubled ingredient 4 times larger than the original recipe?
