So I have a curious question for all you cone 6 firers out there. I recently refired a few pots and the glaze was completely free of microdimples. I have really good surfaces on most of my glossy glazes but there are always really tiny dimples, you can't even see them unless you hold the pot about  8 inches from your eyes. However on these refired pots, they had no microdimples!

So it got me thinking about trying something I have never tired before. 

Firing to cone 6, dropping to 1940F then firing to cone 6 again. Of course the glaze I am using doesn't move at all, so I am not worried about it running off the pots. I am just curious if anyone has tried this method before or something similar. I am super particular about bad surfaces on my glossy glazes, if this solved it I would be happy to do it as refiring all my pots for a better surface seems a bit crazy.

I was looking at commercial ware at a local shop and I noticed almost all of their pots when held up close have microdimples as well, so maybe I shouldn't worry about it too much, but I just can't help to try something new to see if it works.

Anyone? Any Ideas? Comments?

Just an update. I ended up doing a grid test of this glaze and I was able to achieve a perfect surface by finding a glaze with slightly more flux. It is still within limits and is absolutely stunning. Here is a close up. So instead of trying to use my schedule to fix problems, I just did the right thing and fixed the glaze. yay!

Great news! I thought maybe playing with the flux would give you the surface you sought. I am glad to hear it worked. Testing can be tedious but it usually pays off. Thanks for the update.
