Same Bowls after 2 firings

I figured out the problem I've been having with pitting. It's not the glaze since I sieved everything to get out the lumps. I'm overfiring. I readjusted the cone setter a bit too far a few months ago. Got pitting on these, but then sanded down, added more glaze and refired to cone 5. And they turned out rather nice. Some very interesting purplish things going on which you can't quite see in this shot. In any case, lots of new noodle soup bowls to play with!

Why is it that you need to be in the right frame of mind to throw clay? And "centered" of course. For some reason I can't pop down and throw one object in a few minutes, it has to be all the clay in the house. With classic rock blaring. Over the Hills and Far Away put me in the right frame of mind for these. Obviously I was thinking of noodle soup, though the biggest is really mixing bowl size. It's about a foot across.

Now let's just hope my glazes don't act up again like last time!

What's with the Pitting?

So I'm fairly happy with the shape of these pots, but why is it, this glaze that I've been using for 20 years, once in a while pits like this? Is it underfired? Are they putting out less juice so the kiln never gets up to temperature? More importantly, should I try to touch them up with more glaze and refire? I guess I don't have much to lose by trying again.
