These two videos were so much help! After leaving the states doing everything on my own, it is tough to pinpoint issues when no master is around! I have so many books, and none of them give this kind of pinpointing info!
Thanks Babs, where did you go when you left the states that you are unable to find a pottery community? If you have suggestions for future videos, let us know, we are always looking for ideas! And feel free to ask any questions you may have! Send your questions to washingtonstreetstudiosinc@gmail.com
i got pin holes at cone 6 my schedule was 120 celcius per hour up to 900c and then 140c per hour up to 1210 and i hold it for 20 minutes at 1200. what would you suggest i try different next time to avoid this ? ps your videos are of great Help!! thank you so much!!
I had a similar problem and Phil suggested I bisque fire to a higher cone. Most of the organic material burns out of the clay during the bisque firing. I changed to a slow bisque to cone 05 and the pin holing subsided. If you single fire you can slow your ramp for the first segment to 90c per hour and hold at 900c for 10 minutes. This should burn out the organic material before the glaze matures. Let me know how it goes!
With blistering.. is the solution lower cone? I use stoneware for cone 6. So if I did let cone wouldn't that mean the clay would not be vitrified ? Can blistering be from too thick application alone?
Saman, the information shared in the videos is a collection of information learned through college level textbooks, teaching, and experience as a geologist, chemical engineer and ceramics professor (see this video to learn about Phil's background ua-cam.com/video/_6BYyW8m3u8/v-deo.html). There is no single book on the subject that we know about. If you have a specific topic you want to learn more about we can help you find a book.

@@WashingtonStreetStudios thank you alot for your answer, yes all videos are so bebefit to me. I wanna find more info about chemical reactions during firing in Tunnel Kiln of clay brick.
Unfortunately, I'm not aware of a "popular" book that discusses this topic in an introductory manner. It's usually a fairly technical subject, and is mentioned in classic, older textbooks such as "The Chemistry and Physics of Clays" by Alfred B Searle and Rex Grimshaw (Interscience Publishers, 1959) and "Clay Mineralogy" by Ralph E. Grim (McGraw-Hill Book Co., 1969). There's a little mention in "Elements of Ceramics" by F. H. Norton (Addison-Wesley Publishing, 1952). I learned about the subject through my background in geology and my employment as a mineralogist and ceramic engineer. Best bet might be just on-line searches of topics such as: heating of clay, clay sintering reactions, physical and chemical reactions in heated clay, phase changes in clay bodies, composition of fired clay.

So many gems all in one session.
Thanks...Freddie
You are most welcome!
It would be so helpful if the camera was given a chance to do a closeup of the examples being passed around!
Thank you Diane, we've added a second camera as a method of getting a close up. Sorry we can't do anything about our earlier videos!
Mestre deixe sempre legenda, pois eu assisto por elas , sou do Brasil , 💋
I am very sorry, captioning is provided by UA-cam. I wouldn't know how to do it. I hope you still find the videos useful.
