Source/Alternate names: John Post revision of Buck Cream Breaking Red
Source/Alternate names: Clay Times July/August 2004
Firing Notes: cool maximum rate to 800C hold 1 hour
Notes: Alisa Clausen: a thick, covering semi gloss, cream where glaze is thickest and rust where the glaze is thinnest. This is a breaking
glaze, with distinct colour differences from thick to thin. Has shino-like flecked and speckled look where thickest.
Notes: John Post: a speckled rust glaze where thin, turning into a creamy beige glaze if it is applied more thickly. Great in combination
with Berry Rust. Works at cone 6-7. In reduction at cone 7 it turned an unattractive speckled grey. I tried using less tin in order to cut
the cost of the glaze, but the glaze was not opaque enough with 3% or 6% tin. At 9% the glaze was opaque, but did not have the
creamy brightness of the glaze with 13%. I also tried 15% superpax instead of the tin, but that glaze test turned the rust colour a dull
brown and the left the creamy areas looking dingy.
