Hello Brian;
Try setting one layer of glaze in a bisque firing (1000 deg C) Then glaze a=
gain. ie; multiple bisque firings. I heard this is how the Chinese made tho=
se fat thick celadons.=20

I quote Cindy's paragraph and would be interested in hearing from
anyone who has used the material she mentioned (APT-II glaze NRG)
In general, I am interested in experimenting more methods of applying
thick glaze on top of an already glazed surface. I normally heat up
the pot and pour over the warm surface to help quick drying.
There maybe many other tricks and would like to hear about them.
perhaps I should mention that I am not intending to repair or cover a
fault - but rather to develop heavily layered textureS
I would prefer to apply something to the already glazed surface if
possible but do not dismiss the idea of adding something to the second
glaze which will be heavily textured - a quality that might be
affected by some additive

For our celadon we use a medium thick dip over biscuit, biscuit fire,
then re-dip in the same medium thickness glaze. The celadon coarsely
pinholes over some of the chattering we do if a single thick coating is
used.
Brian
We don't usually heat the pot before re-coating over a previously fired
glaze. To make the thick glaze we trail over other coats of unfired
glaze decant some glaze, let it settle overnight, pour & suck off the
water & spray over the pot with the thick settled glaze. You may have to
up the pressure on the spray gun. Our standard pressure for spraying is
40 PSI, for clay or glaze slip we use 100 PSI. This gives a surprisingly
thick coat over fired pots.
