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 KZbin livestream event and then edited to be added to our video library.
Show notes, including handouts, can be found at www.hfclay.com...

Thanks for another great clear , concise lecture, I’ve learned loads about pottery and ceramic glazes thanks to these series of videos 👍

[@WashingtonStreetStudios]

Phil is a natural at teaching and has loads of experience and knowledge of the science behind it all. A true treasure we are happy to share!

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!

Diane, this is high praise indeed, and the driving force behind our making videos! We are thrilled to hear you will be firing your gas kiln fro the 5th time. If you have any questions, don't hesitate to ask and if you have a specific topic you would like covered, just let us know. And please share the channel with your friends and fellow potters to help us grow our community!

Hey great job! Loads of great information!

[@WashingtonStreetStudios]

Phil gave a three day workshop on glaze testing (Saturdays for three weeks) and that is where the samples came from. We got a lot of good feedback on the class. Thanks for the encouragement.

[@lindatortorice9356]

Looking forward to the next glaze episode and better understanding glazes.

[@WashingtonStreetStudios]

Hello Linda, Phil taught a workshop / class on this over three weeks. We decided to create two videos that present both the approach and the results. Part two will be a live stream on October 10nd with the edited video on October 11th. Thanks for the comment and support!

[@xm3364]

Dear Sir, learned a lot from your tutorial clips. Happy Teacher's Day!!

[@WashingtonStreetStudios]

[@isabelarnaud5340]

Amazing and comprehensive. Thankkkssss

[@WashingtonStreetStudios]

Isabel Arnaud, we are pleased that you enjoyed the video, hope you enjoy them all!

[@lunabayaguacatebocasdeltor2925]

Thank you so much for these fabulous videos and podcasts; incredibly helpful, informative, and inspiring. When I get through them all, I'll start over...in case I missed something the first time.

[@WashingtonStreetStudios]

Thank you for watching and commenting! Interestingly enough my daughter spent some time on an internship in Bocas del Toro doing a study on algae. She was there for three months. Really enjoyed the place. It's a small world!

[@lunabayaguacatebocasdeltor2925]

@@WashingtonStreetStudios Small world indeed! The tropical flora and fauna is a world unto itself, aquatic and otherwise. Nice to hear she enjoyed her time there. I'm actually in Maine now.

[@jime96ortega]

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

[@WashingtonStreetStudios]

We're looking.....

[@CPCGR]

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?

[@WashingtonStreetStudios]

Yes, you are correct! When using this approach to glaze testing, the search isn't limited to finding the 'right' glaze combination. The objective is to determine how each ingredient affects the final glaze, and at what point does the ingredient reach the end of it's effective contribution. Great question!
