John, Thanks so much for your very informative videos. All this time I was addressing glaze problems incorrectly.
Now I know what I was doing wrong!!

Thank you so much for taking the time to do this!!

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.

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!

Over-flocculated probably just means it cracks off like in the video.

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.
