Recipe:

20 Dolomite
20 Spodumene
20 Ball Clay
20 Silica
100 gram
ADD
10 Titanium Dioxide
6 Rutile
Note: All raw materials are measured up or down to the nearest half
decimal. Colorants or additives to a 100 gram batch are measured in percent

Results:
Semi gloss, smooth, semi opaque glaze. Caramel (Butterscotch!) ground where
thinner, with a white, streaked shell where thicker. Overall orange
speckling that appears only in the white streaks. This glaze breaks
markedly over edges, with a high contrast between thinner and thicker.

The expansion on this glaze is on the low side - could be a problem on some
clay bodies - test carefully - RR
