Frit 623 for Gersetly Borate

A very shiny gloss, smooth with an overall yellow rutile color. The =
entire test tile has a glassy shell of very opalescent blues and whites, =
streaking and fuzzing, but no dripping.

This test resembles Chris Wolff's Cream Gloss Glaze (archives), or is =
more accurately identical in look and feel.
I think it will be a good glaze for layering over others, like the Cream =
Gloss is. I have found almost any glossy base
with 5% Rutile makes for a good over glaze on rims for a streaking and =
opalescent effect. Will test further.
