The glaze recipe sounds fine. What the nice Israeli is talking about is
compression and several books discuss it.
My guess however is that your problem is with APPLICATION not the glaze.
Usually we glaze the inside of bowls first. We tend to get a thicker coat
than on the outside because the bisque is drier, and absorbs more liquid and
then when we glaze the outside right away the outside is damper and absorbs
less liquid and gets a thinner coat. Are you with me?
Glaze nscrewings andone test bowl with the glaze as you use it normally.
Now measure out a cupfull of that glaze and add 1 tablespoon of water. Mix
well and apply to another bowl. SET THAT THINNED GLAZE ASIDE. Take another
cupful of the original glaze and add 2 tablespoons of water, etc. Test on
another bowl. Combine the two thinned glazes and you now have 2 cups with 3T
extra water or 1.5 T per cup. Try that on yet another bowl.
see what the results are. If my hunch is right the thinned glazes won't
craze, or one of them won't.
Make yourself a hydrometer. Conveniently I had a small piece on them in
Pottery Making Illustrated july/August 2002) and use it....
And a true story. My electric wheel was making strange metallic noises.
Conscientious person that I am I began ripping it apart. After
unscrewings,disconnections and de-wirings I decided to give it a good
cleaning before I took it to the nice electronics man! As I was doing that
I found a little strip of metal, a broken off piece from a wire-style
trimming tool, that had wrapped itself around the seat of the holder for the
bearing and was making a chattering sound. My face is still red....

Hi Lily,
No need for a red face. At least you found the problem. My sister paid $70 to a refrigerator repairman just for him to find that a slice of cheese was blocking the air flow! Talk about a red face - not to mention the cost.
Cheers!

Yes one of my hardest memories from my trip to the USA was paying an eye doctor
80$ to remove hair from my eyes!
And the evil man kept it for himself!
Thank you lily
I will learn: compression.
Don't you think it would be easier to make the inside and just let it dry and than go
on?
Many of my techniques require wetting the ware. When I am glazing I keep the kiln at
100-110 degrees C. I think it can help to avoid too many calculations.
I do not have a hygrometer but I have learnt the con... Dictionary.... I have learnt how
much water a glaze need some need 1-1 glaze water, some, with 30% clay need
more water.
Sincerely
The nicest man in Israel
