Overview
Striker
This style may not reveal (strike to) its target color until fired.
Reactive Potential
Contains: Lead (Pb)
May React With: Selenium (Se) / Sulfur (S)
Forms of Glass
Sheet Glass (-0030, -0050), Frit (-0001, -0002, -0003, -0008) Rod (-0576), and Stringer (-0272, -0107)
Detailed Information
About 001305 Sheet Glass
Cold Characteristics
Color is transparent and varies in density.
Working Notes
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 1225ºF / ºC 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.

Cold Characteristics
Transparent peach with a hazy sheen.
Working Notes
Torch: 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).
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.
Other: 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.
