Working Notes
This sulfur-bearing glass could react with gold-bearing lead (001311, 001215, 000301, 000305) and copper (001116, 001408, 001417, 000144, 000145, 000146) glasses to create darkish interface (lead sulfide, copper sulfide). See our chart Reactive Potential of Bullseye Glasses for extra data.
Very viscous; will circulate later and fewer than different glasses. Usually extra delicate to heat-history and extra prone to present variation in shade after fusing than many opals. When fired on edge, a transparent distinction between exterior and inside surfaces is usually seen (a variation utilized by designers). This glass could turn out to be more and more white with repeated firings. Think about using glass from the identical batch for a given mission.
Dense White (000313) Response Be aware: The fired floor of French Vanilla doesn’t react as readily to lead-bearing Dense White (000313), in comparison with firing the identical mixture in a single firing (utilizing glass that has not beforehand been fired). Nevertheless, this mixture does react when re-fired to a full fuse. The fired and sandblasted floor of French Vanilla will react extra readily with Dense White in a secondary full fuse. This offers a design alternative with the distinction between the sandblasted areas (which do react) and any masked-off areas (which don’t). This distinction is delicate to additional heatwork as reactions will start to develop as little as 1150°F. Our exams present that continued heatwork on this firing will develop a stronger response within the masked off (fired floor) areas. If designing with this attribute, additional testing is really useful.
Copper-Bearing Glasses Response Be aware: French Vanilla will react to various levels with glasses containing copper. The pattern under reveals copper-bearing Turquoise Blue (000116) in varied varieties (-08, -01, -02, -03, -30), fired over French Vanilla (000137, prime half), with every then layered over with White (000113, backside half). The world of interface and results range between French Vanilla and Turquoise Blue. The White doesn’t react with both.
