ron Posted January 19, 2011 Report Share Posted January 19, 2011 I've left several pots outside and half of them have glaze flaking off while the other half is fine?Yes it did freeze several times but there wasn't any water in them. Link to comment Share on other sites More sharing options...
Chris Campbell Posted January 20, 2011 Report Share Posted January 20, 2011 Fired? Unfired? Dry clay? Bisque? What is the question? Do you want to know if you can fire them or do you want to re glaze them? Link to comment Share on other sites More sharing options...
ron Posted January 20, 2011 Author Report Share Posted January 20, 2011 Fired? Unfired? Dry clay? Bisque? What is the question? Do you want to know if you can fire them or do you want to re glaze them? They were all low fired,the question is why they flaked. I have bird houses and bird bayhs that I sell and I don't want these things happening again. Link to comment Share on other sites More sharing options...

For outdoor use you need to make sure your clay is vitrified and you have a perfect glaze fit no crazing. There is an article in Pottery Making Illustrate Jan/Feb 2011 on All-Weather Clay, it has recommendations on which type of clay to use and how to do freeze- thaw test. Your low fire clay probably absorbed moisture through the glaze surface and any unglazed areas and then froze. I spend a lot of time working on clay and glaze combo's and then freeze-thaw testing them. Good Luck Denice (Wichita, KS) Link to comment Share on other sites More sharing options...
