My Condolences to the Washington Street Studio and its artists and followers. I Just discovered Phil's videos here and I am very sad to hear of his passing. A knowledgeable and pottery Legend for sure. What a great educator.
This is the best educative resource I have ever encountered. I listen to it while I work in my studio to re-educate myself in the vagaries and intricacies of ceramics. I am dismayed to read that Phil has passed. What a loss!! I will listen and watch his teachings to the last episode and then go back to lesson 1 and repeat. I can't tell you how grateful I am so thank you all involved.
Sally Hook, thank you for sharing your thoughts. We are fortunate to have captured much of Phil's knowledge in these videos, and he is truly missed. The Potters' Round Table will be restarted in the spring with new presenters, but it will be different!
Thanks, we'll get there. We really just started this year. We are growing everyday and making a lot of new pottery connections. It's a fun experience. I hope you keep enjoying the videos!
Phil, you are a legend! You have such deep, specific and integrated knowledge and you share it so clearly, openly, enthusiastically and with such modesty. What a gift, Thank you!
Sioned Jones, thank you for your encouragement! Please continue watching and share the channel with your friends and fellow potters to help us grow our community!
Fantastic series! Thank you. Perfect informative with just the right amount of technical info which is helpful to teach new and more experienced potters.
easily the most informative, invaluable resource on pottery from a technical aspect. they way he explains things is easy to grasp- i usually feel lost or confused trying to teach myself about things, but so much has just 'clicked' for me with this series! thanks for posting these and making this information accessible
Thank you, Sir, for your videos. They are a source of daily learning for me. I am from India and have a background in chemistry. Presently, I am exploring the world of ceramics.
I feel very lucky to have found your wonderful videos! So much great information but I also enjoy them. My husband and I watch them now instead of Netflix :)
That's really great to hear! There will be more, we really enjoy making the videos. This weekend, on Saturday, 9/12 at 2pm eastern (GMT -4) we will be live streaming a new episode on 'Introduction to Glaze Testing' and there will be a Q&A session at the end. I don't know where you are located or if this is convenient. We will have a live chat and questions can be emailed or given in the chat. The session will be recorded and then posted to our channel as a new video. Thank you for your comment and support!
And we are pleased you found our lectures as well! Please share them with your friends and fellow artists. We also have a podcast version of the lectures that you can take on the go, just look for the Potters Round Table on your podcast platform of choice. They provide a great refresher after you have watched the video.

This is a treasure trove of information. Thank you so much for sharing knowledge. I have a question for Phil. How can I glaze a vessel that has rings on the handles, while keeping them mobile? Is that possible?
Sybil, thank you for the encouragement and please share the channel with your friends and fellow potters to help us grow the Potters' Round Table community! I sent your question to Phil and will post his response as soon as I can!
Hi Sybil, Thanks for your email. It's possible to glaze a vessel with rings, but it's tricky, and the difficulty depends upon the profile of the body, how large the rings are and whether they hang free from the body or tend to lie against it, and how far above the base the rings are. Basically, the rings and the rest of the body have to be kept separated during the whole firing. The easiest solution is to create a small contact area (between the rings and the supporting part) where there is no glaze by applying wax before the glaze. If a ring was on the handle of a small form such as a mug, then it might be possible to support the ring out to the side of the handle (so that it doesn't contact any part of the mug) on the top of an extra kiln post; the "down" side of the ring that rests on the kiln post would need to be waxed and without glaze or supported in a stilt. Phil
I am not qualified to answer your question, you can search for the material safety data sheet for barium carbonate for that answer. We don’t have it in our studio because it is toxic in powder form.
The answer to your question is...it depends. The first requirement for a cone 6 glaze to be food-safe would be that it is fired to maturity at cone 6. If the matt glaze is matt because of the formation of microcrystals (not easily visible with the naked eye) during cooling, then the glaze is likely to be food-safe if the base glaze does not contain any potentially harmful ingredients such as barium carbonate. If the glaze is matt because of undissolved ingredients (due to excess amounts or underfiring), then the glaze may not be food-safe. Whether a glaze is food safe depends upon what all the ingredients are and how the glaze is fired. A base glaze may be food-safe by itself, but the safety still depends upon what the additives, such as the colorants, are. So, the ingredients plus the firing determine the safety. Phil
@@WashingtonStreetStudios Thank you so much, Phil, for your detailed response, I really appreciate it. It turns out, the glaze I was looking at contains barium - so that's a definite no-no :-)
Hi Harry, Thanks for your question! Altitude, and the associated lower air pressure, shouldn't really have any significant effect on the way that glazes melt, but I guess it's possible that the slightly lower oxygen level could effect the color development of certain electric-fired glazes that depend upon oxygen, such as low temperature and cone 6 red glazes. Localized reduction in an electric kiln (from the burn-off of organic ingredients) could be slightly increased. It can have a direct effect on the way that fuel-fired kilns, such as gas kilns, operate because of the lower air pressure and oxygen supply. Phil
Me and my wife open a public pottery studio in Albuquerque last year and have been firing to Cone 6 with a short 10 or 15 minute hold on the end. Most things have fired fine except chocolate clay was some times getting blisters. We recently reduced the firings to cone 5 with a 15 minute hold on the end and no more blisters. Also the Coyote peacock glaze has better color results. I am wondering if a hold on the end of the biscuit fire would help to get more or the organic out of the chocolate clay.
@@harrykuykendall5296 What's the name of your studio and do you have a website? Adding 10-15 minutes on the end of a firing is close to adding another cone. We fire to cone 5 with a 20 minute hold and our pyrometric cones tell us we hit cone 6 throughout the kiln. We have the same blistering with standard 266 at cone 6, but the blistering is diminished at cone 5 with a hold. Since cone 5 with a hold is actually a lower temperature at a longer time to achieve the heat work the cone requires our working theory is something about the dark clays doesn't like the higher temperatures reached by the controllers at cone 6. It is just a working theory and it seems you are seeing the same phenomena. It's possible the lower temperatures is also preserving some of the colors in the glaze as well. Isn't it great to work with something where the same process can achieve different results for seemingly no reason at all!

@@WashingtonStreetStudios Hi Phil, thank you for taking the time to answer my question. I really really appreciate it
Hello,i am interest about Barium carbonat.(BaCO3) is it dangerous if i use in clear glaze for everyday pottery? Thank you for your attention.
I am not qualified to answer your question, you can search for the material safety data sheet for barium carbonate for that answer. We don’t have it in our studio because it is toxic in powder form.
I much prefer the look of a matt glaze but are they food-safe if fired to stoneware temperatures?
MaZ, I'm sure there are and I will send this question off to Phil for a response.
The answer to your question is...it depends. The first requirement for a cone 6 glaze to be food-safe would be that it is fired to maturity at cone 6.
