Great videos … finished building and fired my first gas kiln, did a bisque fire , earthenware and it went great, every piece looked great , before I found these videos , eight months ago , I did know the difference between greenware and bisque !!!!
That's great Erman, we have a podcast as well if you want to listen on the go, just look for The Potters' Round Table on your favorite podcast platform. Thank you for the comment and the encouragement!
Thank you for the encouragement! We have been so lucky that we recorded these videos from Phil before he passed. I hope it stays at his legacy for a very long time! Thanks for watching.
Thank you for your encouragement! There are lots of videos and I hope you enjoy them all. Please share the channel with your friends and fellow potters.
Hi Rita, Thank you for your email. Crazing happens at the end of a firing as the fired clay and solidified glaze are cooling down because the clay and the glaze are contracting different amounts. If the glaze tries to contract more than the clay, then it will crack and break apart into small areas - this is the crazing. As you are probably aware, most materials expand as they are heated and then contract as they cool back down, but different materials (different chemical compositions and crystalline forms) expand and contract at different rates (the CTE - coefficients of thermal expansion). So, if the glaze has a higher CTE (more expansion and contraction) than the clay, it is likely that crazing will occur. Phil
Anna, Thank you for your supportive comment! We appreciate everyone who watches our videos and we are very pleased that you find them useful! If you have a suggestion for a future topic, let us know!
Is it possible to do a lecture on crystalline glazes. I’m really interested I. The large crystal formations in a glaze. Love these lectures. Phil you are a genius. A master in your field. Thankyou so much for all the information.
Sinful Archer, I've talked with Phil, passed on your compliments, and confirmed that he will put together a lecture on Crystalline Glazes! it will take a couple months.
Phil mentioned doing a "hold" in his last video and then again in this video but he never explained how to do that. In my electric kiln, I wonder if I can do a hold if I just turn down the temp from high to medium and let it run at medium for the 20 minutes before I turn it off.
Holding is more difficult in a manual kiln, but you are correct, let it run at medium for 20 minutes. Another approach is to let it run at medium for 15 minutes, then high for 5 minutes to gain the heat lost then shut it down. Thanks for the question!
@@WashingtonStreetStudios Thanks for your quick response. I am watching this series a year after it was made so I didn't think I would see an answer from you. At most, I hoped I could get an answer from someone else who was also new to the series.
Phil, you have inspired me to go back to doing bisque firing after having done 46 mostly successful single firings. Your talks have me looking back at when I started in 2017 and how I really didn't have as good a handle and understanding of the bisque process. I realize that I have been doing a bisque while single firing but being unable to inspect the pots after bisque I feel I am missing a wee bit of the fun. I am using a 21 year old Euclid R-85 3cu.ft. kiln and a Paragon Q-11(for testing) and applying brush on glazes firing to ^ 5/6 on stoneware clay. I would appreciate any advice if you have a particular schedule for your bisque and glaze firings. I used your last schedule on the single firing I just did in the Euclid at the glaze came out well. I will do one more in the Paragon with the same clay body and glaze using your schedule adjustment just to see what the result is, then onto bisque firing again. Cheers and Thank You...Freddie
I find these videos in the series very informative and clear to a novice. It is a 'no nonsense' communications. Thank you.
I hope you enjoy all the videos. Phil was a great resource for the ceramics community.

Please post a picture of your kiln! And thank you for the encouragement.
Love these lectures. Taking notes and re-listening !

I think this channel can grow a lot, best pottery content knowledge on youtube
@@Etienne4201 They need to find a replacement for Phil. He died last month. What a wealth of knowledge that is now gone.

Freddie, I'm going to forward this to Phil and I will post his response. This is way cool!
@@WashingtonStreetStudios No rush, I really appreciate the help and what Washington Street Studios does in sharing the knowledge.
