All the clear recipes I can find are glossy - very very shiny! Is there an
easy way to cut the "shine" on these, or does anyone have a clear matte? All
the mattes that i find are not CLEAR - this is to go over colored clay, so
it is essential that the color show through.
Would appreciate any commercially available suggestions as well.
TIA
Still have the Golden Eagles hanging around!!! What a spectacular sight,
to see them hunting in Surburbia! Hope to set up web site w/pics.

Amy,
I, too, would like to find a clear matte. The problem with matte glazes is
that the matteness is caused by crystal formation, by unmelted particles,
or perhaps by air bubbles. All of these things tend to work against
clarity. You can get colors that come through in a kind of hazy glow (like
Christmas lights through a frosted window), but as for absolute clarity,
I'm not sure if such a thing has ever been accomplished.
I realize my info isn't much help to you, Amy, but I wondered about this
for quite a while and was glad to have it explained to me, even though it
didn't give me that elusive clear matte. The most I've been able to come up
with is a less shiny clear. That's Tony's 5x5. Maybe it's the way I'm
mixing it, but it does seem less shiny than some. You have to apply it
*very* thinly, or you'll get clouding.
If you're doing art pottery, and don't mind a non-fired surface, commercial
clear matte acrylic sprays are both very clear and very non-shiny.

Clear matte, almost by definition, is a mutually exclusive target. If a
glaze is "clear", ie, good glass, then it will not go matte without
altering the glass matrix, leading to loss of clarity.
However, if you want to modify the glaze's surface, without
altering the matrix, then this MAY be possible. Ask your supplier for
Zirconium Zinc Spinel, a crystalline material that will not melt or
dissolve in the glass melt, but will remain dispersed throughout the glaze
melt, including the surface. It may take several tries before you are
satisfied that you have what you want. Start with 2% ZZS added to the
glaze mix and go as high 5%. Above that the glaze may become
discontinuous and show blemishes, turning your pot into a second.
Good tests.

Hi Amy,
The only way I know of to get a transparent matte is to increase the CaO -
Try adding whiting to your recipe 2% at a time. Start with a recipe that
has the most CaO to start with.
If you need more help with this send me the recire you want to try and I
will send you some line blends to try - keep in mind I will be leaving for
NCECA on Monday and will be away for 8 days.

Anyone need a starting point for a cone 6 clear matte
check http://digitalfire.com/education/glaze/cone6.htm
The G1214V recipe at the bottom is where I am at now.
Remember, this page is intended to be a starting point, it gives
info on how to adjust the recipe if it is not right for you.
Get yourself one good base and stick with it, improve it, learn
it, control it. Better to have one good dog that a pack of unruly
hounds!
