Posted 22 Jul 2012they are talking about that in this post a couple days ago
Posted 22 Jul 2012Sorry if this seems obvious but have you made sure all the elements are working?
Posted 5 Jul 2012Thanks for your input,
I have out-gassing when I fire bisque too low. For instance once I fired a test piece of bisque in an 06 glaze load.
Painted, glazed and fired it
However out-gassing happened ) as I got big holes and craters from the gasses still being released as the bisque was not fired hot enough. I googled a bunch and found out about out-gassing.
However that was 2 cones difference, this time it's just one so I am willing to do another test. I just don't want it to craze later on down the line as I've sometimes have had happen before. I thought maybe the crazing happened later cause the fit was almost right but not quit (like one cone off was one guess I had)
Not sure but it sounds like you might be working with stoneware by looking at your cones so I believe earthenware is a bit more finicky than stoneware because of the low temps but I'm just guessing about that part as I've never done stoneware.
I don't believe it will craze either however I have had crazing happen months after a piece was done and was hoping that would not happen with this load.
03 came out to hot so I might try and refire the whole load at 04 with a 10 to 15 min hold this time but I'd much rather have the glaze stick than go too hot again.
