I've been doing ceramics off & on for almost 40 years, mostly in community studios in California & now in Oregon I recently purchased an electric kiln for home use & am re-familiarizing myself w/bisque & glazing formulation, techniques & issues. This series is outstanding & invaluable. The segments are so clearly & succinctly presented, & the technical diagrams & scientific explanations easily grasped. I will be recommending this series to all of my friends & acquaintances at the community ceramics studio where I am currently enrolled. Kudos to the Washington Street Center for putting this together & most especially to Phil Berneburg, the presenter.
Thank you for your encouraging comment! Unfortunately Phil passed away in July 2021. We are thrilled you enjoy the videos and hope to provide more soon!
We are so happy you find them successful. We also have a podcast version you can listen to while you are working, driving and whatever. Just search for 'The Potters Round Table' on your favorite podcast platform or visit anchor.fm/thepottersroundtable and give it a listen!
Have watched a couple of your videos. I have never listened to one in which the narrator could give so much useful information so clearly, so well organized and so quickly. A marvelously presented and helpful pottery source. A wonderful help.
Thank you Paula, we are fortunate to have captured so many videos from Phil and will be able to offer them as long as there is a UA-cam! Please share the channel with your friends and fellow potters to help us grow our channel!
Hi from Argentina Washington Street Studios crew!! These classes are as detailed and specific as it is clear, thank you so much for sharing your knowledge and passion!
Zekryat, There are a group of us that put on The Potters' Round Table, although Phil is the brains behind the content! Thank you for your support and kind words. Please share the channel with your friends and fellow potters to help us grow our community!
We feel blessed to have found you guys. We are new to ceramics and you are providing us with a solid foundation. Great job to all of you 💚 Thank you so much J&K
Thank you for an amazing teacher who gets right to the point. I have been potting for many years and the presentations remind me about things I have forgotten or never really understood from a technical standpoint. Now I have this resource to solve some current problems with a glaze that my collection of books addresses in technical terms. Thanks again!
Thank you Colleen, please share the channel with your friends and fellow potters and help us grow our community. And if you have ideas for future presentations, let us know. Thanks for watching!
Phil is a true wealth of knowledge! He has experience in multiple disciplines to support his ceramic education.

And please share the channel with your friends and fellow artists to help us grow our community!
Thank you so much for all the info you are sharing. You are explaining it in a way that makes perfect sense to me. I really appreciate your willingness to share so freely. I am relatively new to ceramics and this is really helping me.
You are the best teacher to explain the chemistry of glazing and the way you share the best knowledge. We became great fun of yours. Thank you sir, it is sooo much epriciated by us. God bless you👍🙏🙏🙏🙏🌹
Thank you so much for this gold mine of shared knowledge. I was so sad in July when you announce the disparition of Phil. He was a great teacher with infinite skills. He will be missed. I'm new in pottery and ceramic, and so glad to have found your channel. I learn a lot. I have a question about Epsom salt used to floculate the glaze. Could this have an impact (or not) on the food safety of glazes ? Thank you in advance. Sincerely Anne-Marie (from France)
Anne-Marie, Thank you for watching and taking our channel international! Please share the channel with your friends and fellow potters to help us grow our community! This is a very good question, thank you for asking. Epsom salt does not persist in the final glaze, it burns off in the firing process. It is important to consider what you are adding to a glaze to know what will burn off and what persists in the final glaze on the pot. Funny, I had not thought of this in the past!
@@WashingtonStreetStudiosThanks a lot for the quick answer. I hope it's still ok for earthenware (my bad, I forgot to mention that). I have a bucket of transparent low fire glaze which became too fluid and is a good candidate for floculation testing. I fire at 1000°C. I'm concerned by food safety issue in my work. It's one of the limit in learning by oneself!
Hi! Amazing Channel! I def will support you guys! Did anyone ask how fix a glaze that has settled into a hard part at the bottom of the bucket? Would epsom trick work for this? Thank you!! 🙏🏼
Lynn, thank you for the encouragement! Clay settling at the bottom of the bucket typically happens if there is not much clay in the glaze recipe. If you have the recipe, check the clay content and if it's less than 20% of the materials the preferred solution is to add 1-2% bentonite to the glaze so the clay will create a stucture to help keep the glaze in suspension. You will need two buckets, a sieve and a trimming tool, bentonite, a scale and measure cups. First, measure the bentonite and mix it with warm water, bentonite wants to clump, so this really is the hardest part. Remember, you only need a small amount of bentonite, 1-2% of the dry materials, or about 25 grams of bentonite per gallon of glaze. Next, pour the glaze into one of your buckets to expose the hard pan and add the bentonite to the glaze you poured off, mix well. Then get the hard pan of glaze ingredients off the bottome and broken up into pieces. I've used a trimming tool to scrape it off the bottom. It cuts much like a leather hard pot and l've found this the easiest way to get it off the bottom of the bucket. Once the hardpan is broken up into the smallest pieces you can, add it to the bentonite/glaze mixture. Clean the original glaze bucket. Mix the glaze thoroughly. Sieve the glaze back into the original bucket, breaking up the clumps to pass through the sieve. You need to get as much of the glaze ingredients back in the glaze. Mix the sieved glaze thoroughly, then sieve it again. Mix thoroughly, sieve one last time. Every time you use the glaze, or it sits for a long time, mix it thouroughly. If you find clumps, sieve, mix, sieve and mix. I hope this helps and thank you for watching the videos!

I would like to try turning dipping glaze into brushable glaze with the cheap maple syrup suggestion. What ratio prepared glaze to syrup do I use? I found several types of maple syrup that are mostly corn syrup with less than 2% cellulose gum. Is that something that will still work? This is the ingredients for my first choice maple syrup that's sugar free: Water, Sorbitol, Cellulose Gum, Natural and Artificial Flavors, Salt, Caramel Color, Sodium Benzoate and Potassium Sorbate (to Preserve Freshness), Sucralose, Phosphoric Acid, Acesulfame Potassium, Aspartame, Citric Acid.
Stephanie, you want cellulose gum high in the ingredient list, so your first choice is a pretty good one. And you won't need a lot of syrup in the glaze, I normally add about three tablespoons of glaze to a drip or two of syrup. If you try painting on the glaze and it doesn't flow very well, add another drip of syrup. Repeat until it's brushable. Great question! Please share the channel with your friends and fellow potters to help us grow our community!
Every ingredient in a glaze reacts with the clay and other glaze ingredients. To answer this question Phil needs the entire recipe, the clay used and how it will be fired. Can you provide a bit more information and the outcome you are trying to achieve?
Crystal S, epsom salt flocculates a glaze, so to reverse the effects of epsom salt, you need to add a deflocculant. The most common deflocculant is Darvan 7, and you can also use sodium silicate. Add very small amounts since anything you add is changing the chemical make-up of the glaze. Finally, the least intrusive deflocculant is time! Glazes that needed epsom salt added naturally deflocculate over time, albeit a very long time in some cases. A suggested approach is to take a sample of the glaze and test adding Darvan 7 or sodium silicate to see if it resolves the issue and to know how much to add. Good luck and let us know how it turns out!
@@WashingtonStreetStudios Thank you for replying. I have Darvan 7 so I will try it... using a smaller sample of the glaze to test the ratio, as to not mess up the whole bucket this time. Thank you!
@@WashingtonStreetStudios I find your videos very informative & helpful. I have learned a lot. Glazing chemistry is the hardest for me to grasp. I really appreciate your videos. Thank you for taking the time to make them and post them for everyone to benefit from.
M. Clayton, Thanks, nice compliment! I must remind you Phil went to and taught school. It is a shame that financial pressures are forcing schools to shut down many of their art programs and that's why we are here!
I'm in awe of a man that has made a model of clay molecules using Newcastle Brown beer mats!
Phil was a great teacher, potter, business partner and friend! He is missed.

When I mix my underglazes I add some glass powder. That melts before the glaze and it doesn´t crawl.
I've not tried that, sounds briliant!+

Ah, crawling. The bane of my existence.
Indeed. It crawls until it hits a pinhole, then....
Thank you - Can we add soda carbonate to make a glaze creamed .
I've sent the question off to Phil, I'll post his response.
Every ingredient in a glaze reacts with the clay and other glaze ingredients. To answer this question Phil needs the entire recipe, the clay used and how it will be fired. Can you provide a bit more information and the outcome you are trying to achieve?
