- Welcome to Pottery Shorts, brought to you by The Potter’s Round Table, the topic for this episode is Tiny Details in a Glaze.
Why do glazes look the way they do? We know a lot about color, but what about matte glazes, depth in glazes, textures, and glossy glass like surfaces? In this pottery short we explore what a close-up view of a glaze might look like.
The Potters’ Round Table is brought to you by Washington Street Studios, a community pottery studio, gallery, and pottery school located in Harpers Ferry / Bolivar, WV. We exist to provide ceramic artists an affordable, fully equipped studio space for aspiring, emerging and established artists to share their creative energy and knowledge in an environment designed to support the ceramic artist. If you want to learn more about Washington Street Studios, visit our website at www.hfclay.com/.
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.
This video is one of our steps to share our passion for the ceramic arts, creative energy and knowledge with other artists and art lovers. We also created an audio version to expand our audience.

Man, you are a treasure! Not just for your extensive and detailed knowledge of ceramic materials, but also (and especially) your impressive ability in explaining concepts to relatively numpty headed viewers like myself. Huzzah!
Tom Truett, Phil was a treasure, but he passed away last year. I feel so fortunate that we were able to capture this complete set of videos explaining the ceramic process. And we have Phil's uncanny ability to explain the most difficult subject matter to the rest of us! Thank you for your kind words, it's the legacy Phil wanted to leave behind!
I hope you are able to enjoy all the videos!
Thanks again Phil, kind regards, John.
John, Thanks for watching, regards!
These videos are the greatest!
Caitlin, thank you for the encouragement! Please share the channel with your friends and fellow potters!
Great video with a wealth of information 👍😊
Thanks mosseyw, this is one of my personal favorite Pottery Shorts!
Very useful information. Thanks again
Thanks Cindy, we appreciate the encouragement!
Excellent info. Haven’t seen this topic discussed before in ceramics sites I follow. Thanks for presenting it!
Thanks for watching Kevin, and for commenting! Please share the channel with your friends and fellow potters and help us grow our community.
Excellent lecture, so very informative ... Thank You!
Awesome, thanks for watching! Please share the channel with your friends and fellow potters and help us grow our community.
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.
You are most welcome
Love to see that list of patrons growing! I also love when Phil brings examples to show - perhaps that could be a part 2 !
Yes Ben, Phil and I have discussed samples and handouts, and the need to have them for as many videos as possible. Thanks for helping us improve our channel, and for being a patron of the show.

Good thought! I’d like to see samples.
About undissolved ingredients -- they aren't invariably a fault; the character of Song dynasty celadons apparently arises partly from undissolved ingredient particles. (Ref: Ceramic Masterpieces, by Kingery and Vandiver) // Nice explication. Thanks!
Jon, good point. Most of these characteristics are not faults on their own, they may not be food safe, or they may make some glazes not appropriate for all purposes. They are simply characteristics that result in a different look or feel to the finished piece. Thank you for the great comment! I love this community.
Another amazing short video!
I have never seen all these different phenomena gathered together and discussed in a single diagram~ very interesting indeed! Thank you~
You're welcome, thanks for watching!
As always very informative. Thanks for sharing!
I Single Fire and use brush on glazes and the last two pots I fired separately in my Paragon Q-11 had small pin holes. The cooler temperature here in Florida(45-50F) meant the kiln cooled down quite fast after shutoff. I did not programme in a slow cool as the pots have been coming out with good results prior in the warmer weather.
Do you think adding a slow cool and re-firing will make the pin holes dissipate into oblivion not to be seen again?
Any suggestion to changing my firing schedule would be very welcome.
Seg.1 Rate 200 Temp.210 Hold 60...Seg.2 R150 T 500 H 0...Seg.3 R 400 T 2180 H 0...Seg.4 R108 T 2228 H 30.
This last Single Fire resulted in ^5 completely bent over and ^ 6 bending just beyond the base mark of the support cone not touching the floor. I call it a strong cone 6.
Thanks in advance for any ideas...Freddie Moretti
Freddie, I've forwarded your question to Phil and I will post his response when recieved.
@@WashingtonStreetStudios Thank you very much, really enjoy his talks.
Hi Freddie,
Thanks for watching and for your question! I think that the pinholes are due to the fact that the early part of the firing schedule is too fast, and all the impurities in the clay are not being burned out completely, resulting in gas bubbles coming up through the melted glaze. When single firing, you still need to include a slower bisque portion early in the schedule. The cooling portion doesn’t have much to do with pinholes. As a suggestion, you might want to slow down the first two segments of the firing, as follows: Seg. 1 rate 100 to 250, no hold, Seg. 2 rate 200 to 1100 no hold, then continue with your schedule. Unless the pinholes are very large and the glaze is thin, refiring will probably erase the pinholes. For the refiring, you could probably use your original schedule. Good luck,
Phil
@@WashingtonStreetStudios Thanks Phil, I will print this out and try the schedule on the next firing whether in my Euclid or my Paragon test kiln. Will probably do the same glaze and same clay in the test kiln to compare results.
Thanks again!
Thanks again for the advice Phil, tomorrow I am going to single fire the 3cu.ft. Euclid using your advice with an addition at the beginning as I like to make sure my pots are dry.
I weigh them on the grams scale until they stop losing weight as a gauge and then I give them that first hour to back up the drying process.
R100 to 210/ R100 to 250/200 to 1100/R400 to 2180/R108 to 2228 w/30 min. hold.
Thanks again...Freddie
Excellent lecture, so very informative ... Thank You!
Must have been really good to get a double comment!
