-------------------------
100 gram
Note: All raw materials are measured up or down to the nearest half =
decimal. =20
Colorants or additives to a 100 gram test batch are measured in percent =
to the 100 gram test batch.
Results:
Dry, but melted stark white, covering, mat glaze. Smooth surface.
More a glaze then a slip, but seems just melted enough to be smoother =
than a slip.
Could be good for those who need a white slip/glaze between a dark clay =
body and a transparent glaze.
This base may have good possibilities for coloring. Will try in the =
next tests.
