John Britt said...: Glad to help. Remember glazes are acidic and basic like pool or spa. You use the same stuff to balance them. Epson Salts and soda ash.; December 20, 2012 at 1:41 PM
la paloma Texas pottery said...: John, Thanks so much for your video on Deflocculated and Flocculated glazes. What does the term "over flocculated" refer to?
I have around 20 blogs I read daily and I always scroll down to read yours first!; December 21, 2012 at 5:27 PM
John Britt said...: Over-flocculated probably just means it cracks off like in the video.; December 21, 2012 at 9:22 PM
Julie said...: John, I am still trying to straiten out this thick glaze. Can't just add h2o. I added Sodium silicate -it has gotten thicker. The problem is cracking off while trying to dry. I added epsom salts to it about a yr ago because I thot it was thoraxic issue.
