I have searched the archives and can not seem to locate a matte / non
glossy clear glaze that would be used in a cone 6 oxidation, would
anyone share a recipe with me? I plan on using it on porcelain. I have
MC^6 , however none of the recipes in are what I am looking for as all
base glazes seem to be glossy.
Thanks,
Judy

I tested about 4 or 5 matt clears and all of them craze on my clay unless
you put it on very thin.
I thought I had one, but it crazed over time. I am using Ellen buff from
Highwater.
If you can to try them I will round them up and email them to you.

Hi Judy,
The reason you haven't found much is that what you are searching for
is a bit of an oxymoron. What makes a glaze matte also makes it less
clear--tiny crystals or surface roughness. You might be able to get a
translucent semimatte but that is about as close as you will get. You
could also try using a glossy clear and then grit blasting the
surface to matte it a bit--but this will also make the glaze less
transparent.
Regards,
John

I think what both Judy and I are looking for is what painters
call matte. To potters, matte obviously means a diffuse body, to
painters it is strictly a surface gleam reduction with no
modification of the colour under it.
Is lustre the proper word to use in potters' circles?
I read of metallic chloride compounds suspended in an oil/resin
based medium which is applied to the already glazed and fired
pot. In a subsequent firing (to around 750oC) the resin/oil burns
out creating a reduction which draws the oxygen out of the
metallic chlorides to create a thin film of pure metal on the
surface of the pot.
Is this the sort of thing that Judy & I are looking for?

Judy,
Regarding your search for a matte ^6. I have had good success at cone 6
with the digitalfire G1214Z. You will lose some of the clarity compared to
a glossy clear but that is to be expected because it is a true matte. I did
tests with other formulas before coming across this one and have found it
very successful for my some of my sculptural vessels and tiles. Pay
attention to thickness. If you are using it over underglaze work, it may
crawl if used too thickly. I have found that thinner is better with my own
work. There is a good discussion of this glaze and the recipe at the
digitalfire site. Google: digitalfire G1214Z or go to the following site:
http://ceramic-materials.com/cermat/education/122.html
Hope that helps.
Kind regards, Megs

This may not be a stable glaze by the way - not sure it is well melted
enough at cone 6 and there is not enough silica for a durable glaze.
