Test The Glaze Firing

The witness cones on the far left are from the top shelf.  They are Cones 4, 5, and 6 and the two single ones are Cones 5.  Cones in the middle are also 4, 5, and 6.  You can see the 4 bent completely and the 5 just a little.  The cones on the right are all from the bottom shelf - again 4, 5, and 6, and the single one is a 5. But as you can see none of them really bent.   

These two pieces are both done in Celadon Froth.  There was no blistering but I need to make sure I hold it in the glaze long enough to get it thick.  You can see the blue is where it was double dipped and the brown is just a single dip.

Again, Celadon Froth - this was on the bottom shelf which only got to about Cone 4 but it came out nicely.  Even the Celadon Froth pieces on the top shelf came out fine - no blisters.  A great glaze!

This is red chun but it came out mostly grayish.  When not layered with other glazes it did not blister.  These were on the top shelf so it got hot enough and the glaze was plenty thick enough.  So maybe it got too hot or maybe it was too thick.  Gotta try to figure this one out because I love red chun when it works!

This is cappucino with the rim dipped in red chun.  This was on the top shelf and apparently got too hot because it's all blistered.  I think it's the cappucino that blistered because the pieces that were just done in chun and were on the top shelf didn't blister.

Another blistered cappucino and red chun.
