urfriedrice Posted Monday at 11:35 PM Report Share Posted Monday at 11:35 PM Hi I'm a beginner potter and I was curious if unglazed firings aka just no glaze firings up to cone 6 would make the pots fuze together if they touched. I know bisque fires don't cause pots to fuze but I wasn't sure about higher temperatures. Thanks everyone! Quote Link to comment Share on other sites More sharing options...
Babs Posted Tuesday at 12:49 AM Report Share Posted Tuesday at 12:49 AM Guess it depends, if your clay is not reaching the top end of its firing limits, be ok imo but be mindful how you stack the kiln. You could do a one firing, like @oldlady and follow your bisque schedule to top of that, then switch to your glaze firing schedule ramps till reach target temp.

JohnnyK Posted Tuesday at 06:04 AM Report Share Posted Tuesday at 06:04 AM Best way to find out is to run a test with some scrap pieces of the clay in question... Quote Link to comment Share on other sites More sharing options...
Kelly in AK Posted Tuesday at 08:35 AM Report Share Posted Tuesday at 08:35 AM It’s possible depending on the clay, but unlikely. As @JohnnyK says, test it out. Some clays (porcelain mostly) fired to their absolute limit will get sticky. If kiln wash sticks to a bare foot that’s a sign. Quote Link to comment Share on other sites More sharing options...

Mmm very wise. Thanks, I'll give them a test! Quote Link to comment Share on other sites More sharing options...
oldlady Posted Tuesday at 11:49 PM Report Share Posted Tuesday at 11:49 PM your question is intriguing. why exactly would you fire to top temp without glaze? did you have glaze but it dried up?? do you intend to make flower pots and never planned to glaze them?? do you use stoneware that matures at cone 6 or an earthenware that matures at cone O6?? that is such a standard mistake of new potters who have never fired their work. please elaborate. do you have any experience glazing anything?? where did you learn whatever you now know?? tis a puzzlement.
