I made up a batch of Mastering Cone Six Gloss #1 with Bright Sky Blue
colorants as recommended in the book. With no time to do test tiles, I went ahead
and dipped a whole kiln load an fired them. Because of too much water, a
lot of the items were washed out looking after I fired them. In the past, I
had used spray starch but didn't have much success. After searching the
archives I found Janet Price's recommendation to use Elmer's Glue. I adjusted the
water and re-dipped and fired. Good results. Most now look like they were
supposed to while others look like a high quality floating blue.......
Thanks to all who contribute to Clay Art--especially in this case Janet.
Best regards,

I once tried using corn syrup. You cannot imagine what a disaster that
was. Never, ever again would I do that. How thick did you put the glue
and did you dry it first? I was recently re-reading an article on
defloculating glaze to make it paintable to glaze pieces fired too high to
absorb the glaze. I have decided to make up small jars of 'paintable'
versions of my glazes but have not yet gotten what I need to deflocculate
(and then I thought - how do you keep it from turning into rock when you
do this... do you simply defloccuate a batch when in need?)

I just fired a kiln load of 'refires'. Unhappily, I did not have the same
success that Bruce reported. I had a dozen or so pieces that needed the
refire--or the hammer. Out of that dozen, only 3 were successful. Perhaps
the problem for me was that I was trying to cover too large of an area.
And, because it seemed that the glaze was too watery, I had poured off a lot
of the water to give me a thick glaze to hang onto the pots. It seems that
the weight of the glaze pulled itself down off the slopes of the pots. I am
happy to have the 3 survivors--the rest met the hammer early this am--and I
think I've picked up some experience that may serve me better in the future.
