This style may not reveal (strike to) its target color until fired.
Contains: Lead (Pb)
May React With: Selenium (Se) / Sulfur (S)
Forms of Glass
Sheet Glass (-0030, -0050), Frit (-0001, -0002, -0003, -0008) and Rod (-0576)
About 001215 Sheet Glass
Varies from lighter to darker; sometimes with lighter dappling in single-rolled sheets. Generally lighter and slightly more blue/pink than Cranberry Pink Transparent (001311).
Color usually deepens on firing. Possible dark interface reaction with selenium and/or sulfur glasses (000137, 001122, 001125, 000124, 000125, 001137, 001437). Less viscous (softer) than most other glasses. Some gold-bearing striking glasses, like this one, should be fired with a 2 hour hold at 1225°F during the initial stages of the firing cycle. If fired without this hold, they may not strike at all, or they may strike but appear spotty and have a blue-brown cast, as opposed to the desired target color.

**Remainder of cycle depends on the thickness of the piece. Consult the Bullseye Annealing Chart. For color-sensitive projects, we recommend testing the cycle you plan to use by fusing a small sample of a similar setup in the same kiln as the project to best predict final color results.

About 001215 Rod
Pale transparent blue to lavender. In some lighting may look similar to Neo-Lavender Shift (001442-0576), Cranberry Pink Transparent (001311-0576), and Cranberry Sapphirine Transparent (001342-0576).
Torch: 001215-0576 strikes to a transparent pink in the flame. Work in a cooler, oxidizing atmosphere. May develop a light brown color on the surface of the glass if worked in the presence of too much propane (or fuel). Light Pink strikes more reliably in larger applications, such as a core bead.
Kiln: A linear, streaked design may develop upon firing and may be visible whether fired lengthwise or on end. Hue and saturation may also differ slightly when compared to sheet glass; a wider range is accepted due to changes that occur in the forming process.
See Working Notes under Sheet Glass tab for additional firing information.
Other: The resulting light pink is more transparent than torchworked sheet glass of the same style (001215-50, 001215-30). Consider encasing with clear to protect the surface from developing a light brown color in the hotter, neutral flame chemistry that you would use for most other styles. We advise labeling all striking glasses.
