Harry Potter Posted July 26, 2018 Report Share Posted July 26, 2018 Ok, haven't been in my studio for 4 years. Health and other issues. Got it cleaned so ready to start again. I have numerous pieces that I made prior to quitting. They have been bisque fired and are all glazed. I was working with stoneware and earthenware, I don't have my notes. should I just fire all to earthenware temps. Is there any other way to tell what is stoneware and what is earthernware? Suggestions appreciated. Ps after all these years, it's almost like starting over. Thanks in advnace Harry Potter Link to comment Share on other sites More sharing options...
neilestrick Posted July 27, 2018 Report Share Posted July 27, 2018 No good way to tell unless you know your clay bodies. White earthenware looks like white stoneware, but terra cotta is pretty easy to recognize. You could just fire it all to cone 04, and those that don't melt you can refire to cone 5.

Thats the safest way-I suggest from this point forward mark your pot bottoms if you are using different temp ranges-as its just a real disaster waiting to happen. I will add its not if but when.

Harry Potter Posted July 28, 2018 Author Report Share Posted July 28, 2018 In case it didn't post, Thanks to All. I finally remembered if the bottom is glazed it's earthern ware and if not then stoneware. Wow a lightbulb moment. LOL Link to comment Share on other sites More sharing options...
Gabby Posted July 28, 2018 Report Share Posted July 28, 2018 And now that you are back to things, keeping notes might be good. You could either sketch the items you make in a notebook and note the clay and glaze or take a photo of the whole finished batch and similarly attach clay and glaze labels.

Magnolia Mud Research Posted July 28, 2018 Report Share Posted July 28, 2018 My approach is to fire everything to earthenware temperature. The items that have glazes that have not melted are stoneware and can safely be fired again to stoneware temperatures. My colleagues and I often fire glazed stoneware to bisque (earthenware temperature) temperature to "set the glazes" so that the pieces can be shipped elsewhere for final firing.
