Hi Louis,
Thanks for the info, but the problem occurs on the verticle surfaces of my
test tiles where the glaze is running in rivulets. Those tiny, open bubbles
are occuring at the end of the run/rivulet. This seems to be a typical
problem for Andies and Sharons fake ash...just wondering how to solve the
problem and didn't want to re-invent the wheel if I didn't have to.
I appreciate your input, Louis

Greetings,
I know that Andy's and Sharon's fake ash, cone 6 glazes, have been discussed
A LOT!!!
So, sorry for the redundancy in asking the same question that has been asked
before. I have not been able to find any posts, however, that talk about a
solutuon to a bubble problem.
My question...I am getting, what some have called in the past, tiny spit
bubbles in the thicker parts of the glaze. I know that some of you out there
have suggested that the cause might be dolomite, GB, or a low bisque, but
for those of you who have tried to rectify the problem, what have you found
to help iliminate those bubbles?
Thanks for your help, the collective knowledge of this discussion group is
amazing and much appreciated!!

If it is bubbles in the bottoms of pots, one solution is to put some
water in the bottom of the pot before you glaze, then pour it out and
glaze. This will give you a very thin coat at the bottom and the pools
of glaze won't be as deep.

Lisa you might want to try putting it on a tad thinner. I have a fake ash
commerical glaze that would do the same thing and it worked much better by
thinning it out a good bit and spraying it on. Also you might want to try
the common way of decreasing the melting point of the glaze by increasing
the flux 2% to 5%. Decreasing the kaolin content will also do the same
thing.
I am no expert so there may be a lot of other suggestions.

Thanks Randy,
I'll give the flux and a kaolin a try.
I appreciate it!!
