neilestrick Posted April 18, 2013 Report Share Posted April 18, 2013 The glazes will likely craze. Bad glaze fit. Link to comment Share on other sites More sharing options...
Chris Campbell Posted April 18, 2013 Report Share Posted April 18, 2013 Neil is right ... You will either under fire the clay or over fire the glaze. Under fired clay is weak and over fired glazes crack and/or run. However ... It all depends on what you want to do and how you want to do it. If you love the glaze color and can't get it any other way then you have to adapt. You could fire the clay to its temperature of Cone 6 then glaze it and re fire to Cone 04-06 If it were a sculpture or other non functional object you could just glaze and fire the whole thing cooler ... Maybe not as low as Cone 04 ... you might try higher temps to see what happens. Maybe Cone 2, 3 or 4? Put it on something so if it runs you won't have a shelf to clean.

oldlady Posted May 3, 2013 Report Share Posted May 3, 2013 gypsy, your title suggests that you might think that cone 06 is hotter than cone 04. the reverse is true. maybe i am misreading you or maybe i have always assumed that whenever anyone talks about a range of temperatures the lower number is mentioned first. from low to high.

Nat Posted May 3, 2013 Report Share Posted May 3, 2013 I often use earthenware glazes on a stoneware body...sometimes it crazes, sometimes not...I happen to love the crackle effect though, but if you're glazing items that need to be food safe, it's not so good.

Claypple Posted May 4, 2013 Report Share Posted May 4, 2013 The answer depends on what Gypsy is making and what glaze she is using. Chris is right, re-firing up to ^6 and then glazing at ^06 probably is the most common solution. Link to comment Share on other sites More sharing options...
