Hi! Can anyone suggest what to do if I fired my items at cone 5, after glazing them with Amaco Seaweed PC-42, and I got a bunch of pinholes, and even one sharp bubble on the top rim of a cup?
I'm using a medium-sized Cress electric kiln (all digital, so no cone sitter). I set it at cone 5, medium speed, and no hold.
Help and suggestions greatly appreciated!
What claybody are you using? Did you apply any underglaze, oxide, or wash?
