AndreaB53 Posted May 18, 2015 Report Share Posted May 18, 2015 Can anyone help? I fired a bisque yesterday (electric kiln) and found this morning that I hadn't switched over to automatic and the kiln ran at 960 for 8 hours. Can anyone tell me what I can do with the results Link to comment Share on other sites More sharing options...
Amy Eberhardt Posted May 18, 2015 Report Share Posted May 18, 2015 There are other folks here that are a heck of a lot more knowledgeable about this than I am, and I'm sure one will be along soon to answer this better than I can. That being said........ The first question that needs to be answered is: Are you talking degrees Fahrenheit or Celsius? If you're talking Celsius, then you reached a cone 06 and everything should be just fine for a bisque firing of most clay bodies. If you're talking Fahrenheit, then you didn't get even to a cone 018. Depending on what kind of clay you're using, you'll likely need to fire it up again, as the necessary temps to achieve a burn off of the organics and such didn't happen. The second consideration is that of which clay body you're using. Some need to be bisqued at higher cones, others at a lower cone. Your bisque firing also influences how well your glaze is going to work out. So, more information will help out a great deal in getting a more concise answer.

Min Posted May 18, 2015 Report Share Posted May 18, 2015 Hi AndreaB53 and welcome! Not sure if I'm understanding how you fired, did run it at 960 (C or F) for 8 hours? Did you have any witness cones in the kiln? Is the clay earthenware? Not very scientific but try touching a pot with the tip of your tongue, if it sticks a bit then the clay is still porous enough to glaze. If it doesn't stick at all then you will have hard time with getting a good even coat of glaze to stick to the pot. If it is overfired and not porous you can try heating the pots up to around 200 and then very quickly glaze them, if you have access to spraying the pots that would probably be the easiest. It's a crap shoot and the results are not usually as good. Are there any bloats? If you only got to 960F then refire to what you normally bisque to.
