Question Posted By: Kary Monday, December 11 2006 11:26:03 Suggest Answer

I have been using Amaco Versa clay #20 in my classroom for about one school year now, because I like the way it handles the thick walled student sculptures. On my own work however, It cracks unpredictably in the kiln- Seems to have trouble with crazing no matter what glazes I use. I have tried all of the common solutions: slow cool, higher bisque etc. but I would like to know what glaze series IS compatable shrinkage-wise with this clay?

    Kary,

    If you are bisque firing the clay at a good cone 04 (1975ºF - 10 hours) and glazing at a Cone 05 (1915-1925º - 8 hours)you should be doing okay. How long are you allowing the clay to dry before bisque firing? What glazes are you using and what temperatures are you firing at? My email is ljenkins@amaco.com.
