Dear Marianne,
One of the "presents" I got from one of my workshop hosts was glass =
frits, shards and thin Bullseye sticks.
This is what I did.
I threw small bowls and when they were green, I painted a heavy slip =
around the middle of the inside of the bowl, like a belt.
I dropped the glass frit in the center of the bowl where there was not =
slip, and then rolled the bowl around in my hand. The=20
glass frit stuck to the slipped areas like sugar on icing. You have to =
work fast enough that the slip is still wet.
Then I laid a few pieces of the Bullseye sticks across the bottom of the =
inside of the bowl, like pickup sticks.
After the bisque, the glass was fused enough to the clay so it would =
stay there when I glazed the pots.
I glazed them with Tony Hansen's 20x20 with zircopax. The glass powder =
melted nicely into the glaze and=20
spread out a little. The sticks melted, but the glaze crazed over them. =
In general they are nice little bowls for
tea lights or maybe salt. I tried a bowl with a chunk of glass in the =
middle. It melted and cracked and the=20
glaze crazed over it. A lot of cracks.
The glaze frit on the slip is nice, because the glass is contained in a =
painted design of your making.
Runny glazes
All of my runny overglazes, gloss, have 4 to 7 percent Rutile in them.
=B4
This is a runny, streaky, gooey glaze for (decorative?) rims.
Streaky Pearl=20
from Toni Martens
28 Postash I use my feldspar
14 Whiting
14 Dolomite
10 Zinc ox.
3 Lithium carb.
4 Bentonite
20 Silica
7 Rutile
This is a runny, streaky, fluid glaze for (decorative?) rims.
Can be white, grey or blue or all.

Hi Alisa,
The glaze below is short of alumina and silica - which you know of course -
but if you wanted to stop the crazing and make it semi stable for colours
you would need to up the silica to 60 - that would help the stability a lot
- it will not run as much I'm sure but it will run some.
The way to make any glaze run is simply reduce the alumina till it runs the
way you want it to.
