BTW, do you have any idea where to go to buy bulk sieve mesh? I want
to build my own but have struck out finding the mesh.


I got mine from McMaster-Carr. They are a huge industrial supply
operation but they sell to individuals and have great prices. I got
"type 304 stainless steel woven wire cloth" in 1ftx1ft squares
for about $7.50 each last year. Here are the part numbers
to look for on their site. (Forgot their URL, but Google on
McMaster-Carr to find it):
20 mesh 85385T851
40 mesh 85385T864
60 mesh 85385T866
80 mesh 85385T869
100 mesh 85835T872

Total for all 4 pieces was $34.59 plus 4.25 shipping...
and delivery was in only 2 days! They also have
larger sizes as well.

I have this happen all the time with commercially made clear glazes...and I
have tried three or four. I'm not quite ready yet to make my own
glazes...but I found, by doing test tiles that I can sometimes get the clear
glossy sheen I am looking for by using only 1 0r 2 coats. Try some test
tiles for yourself and see!

Hi all,

I'm having a hard time with a store bought clear glaze (cone 6). I bought
this glaze in powder form and mixed it myself. Since then I'm having
random problems with it, usually on big bowls with lots and lots of work
invested in them. Problem is: milky white translucent spots develop in
place where I guess the glaze is to thick, except we've been extremely
carefull about it not being to thick. What would cause a glaze to be so
extremely sensitive to thickness? Or is it a combination of the firing
conditions and this specific glaze? I spoke to a local potter about it
and
he said he makes his own clear glaze and never sees this problem but has
seen it with store bought glazes before.

I posted some pics for anyone crazy (or nice!) enought to have a look I
would sincerely love any advice or comments...
