Hello all!
This is my first posting to this list. I happened upon the ClayArt archives
a few weeks ago and was so ever grateful to find such a resource of
knowledge and information. Now I have a dilemma of my own:
I've acquired all the equipment, materials, bits and pieces of another
potter's studio, including glazes which she had already mixed, their age
unknown. I'm just getting started on setting it all in moption as my own
studio. I've done two cone 06 bisque firings already and now I'm starting in
on glazing. But something is definitely wrong. Both glazes (cone 6) I have
applied to the ware are cracking and flaking off the pieces.
Any ideas on what might be causing this and what I can do to make it stop?
Is the clay repelling the glaze? Or does the glaze need some sort of
addition to make it more cohesive? I am stumped. Any advise would be greatly
appreciated.
Many thanks,
Shari Smith

Hi Shari
welcome to the show.never a dull moment i've found.
I use veegum-t in my glaze, makes it less powdery and
seems to bond better to the clay.

Shari, we can't give you any advise, but maybe we can come up with some
advice. (Sorry, can't help myself, and please let's not have that debate
again.)
Basically, we need more information. Probably your raw glaze is being put
on too thick, and probably it has too much raw clay in it or too much
magnesium carbonate, or too much of something that shrinks too much when it
dries. Give us the recipe and we'll take a crack at it.

Try a little starch from the grocery store. The kind that is used when
ironing starched shirts.
It makes a pretty good binder and is cheap.

Shari, Sounds like your glaze if to thick. If you are dipping, add a little
water; if you are brushing, thin down the glaze, or brush on only 2 coats.
