Hello, I am a new member (and new to pottery in general) and have struggled to find the answer to the glaze defects I have been experiencing on previous posts in this forum. I am having trouble with pinholing/pitting/airbubbles (not sure exactly what to refer to it as). Most of my glazed pottery either has loads of little holes (this is especially bad with black underglaze topped with clear) or lots of tiny bubbles trapped beneath the surface.

I am using tucker's mid smooth stone and bisqueing to 04 with a 16 minute hold. I am dip glazing using amaco white with a 16 minute hold. I have noticed after I dip glaze that lots of popping bubbles appear on the outside of the pots in the glaze. More hold time? Is my kiln broken? Any help would be good . Thank you.
