Lasse Ostman has a few glaze recipes on her website. One of these is S422
Semi matt golden yellow. She fires this to 1270 C with a one hour soak. It
is described as a very intensive golden yellow. I fire to a very full cone
6. I have never paid much attention to what cone a glaze is supposed to go
to (as long as it is from 5-10) and as a result have a few very nice glazes
that are being underfired. At cone 6 oxidation, this glaze is an
interesting pale yellow cream that pools and just has a very interesting
surface. I just tried it on a vertical test tile (usually I do most work
flat) and it was more in the tan range (just a little). But it was
impressive and would be worth a test on a small bowl. A very elegant glaze.
Here is the recipe:
Potash feldspar 64.35
whiting 18.93
epk 3.15
albany slip 5.68 (I used Miller's/Laguna's albany
substitute)
rutile 7.89 (I used the 325 mesh light
that US Pigment sells)
FeO spanish 6.31
It works fine single fired.
