KEY TO ICONS

Copper Copper  Lead Lead  Selenium Selenium  Silver Silver  Sulfur Sulfur  Striker


 REACTIVE ICE CLEAR 001009

001009 Reactive Ice Clear  

   May react with: Copper Silver

Cold characteristics
Similar appearance to 001101 except it may include a slight tint of color (blue to green).

Working notes
Easily confused with 001101. Reactive combinations have the potential to create an interface color, which may continue to develop through multiple firings. Copper-based reactions tend to be variations of deep red to black, while silver based reactions are more likely to develop as earth-tones. Reactions are generally related to the amount of copper and silver content, heatwork and surface area contact. Learn more about this style by downloading our Get a Reaction PDF.

-0031 (rainbow irid)
Strong reactions may permeate the iridized surface, finding greater surface contact through thinner sections of the irid coating (gold, silver) and minute fissures throughout. Crackle patterning is generally more open where the irid coating is thicker and transitions to dense coverage in thinner sections. Expect variation.

LIGHT CORAL STRIKER 001205

001205 Light Coral Striker

   Contains: Lead

   May react with: Selenium Sulfur

Striker

Cold characteristics
Striker. Transparent clear. On edge, resembles 001101.

Working notes
Color usually deepens on firing. Possible dark interface reaction with selenium and/or sulfur glasses (001122, 001125, 000124, 000125, 001137, 001437, 000137). 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. This full-fuse schedule effectively strikes these glasses:

Rate Temp Hold
* 1225 2:00
600 1490 :10
9999 900 **

* The initial rate of heat is not a critical factor in successfully striking gold-bearing glasses. Choose an initial rate of heat appropriate to the scale and design of the project that you are firing.

** 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.

PINE GREEN 001241

001241 Pine Green

   Contains: Sulfur

   May react with: Copper Lead Silver

Cold characteristics
May include brown areas.

Working notes
At full-fuse temperatures, the brown areas appear as transparent wisps. Such wisping is more noticeable in a thin (-50) sheet and would be amplified by fusing an opalescent glass style under it. Unless a pure pine green is desired, these uniform wisps could be used as a design feature.

BURNT SCARLET TINT, STRIKER 001823

001823 Burnt Scarlet Tint, Striker

   Contains: Lead Silver

   May react with: Selenium Sulfur

Striker

Cold characteristics
Appears almost clear with blue/green tints.

Working notes
Color usually deepens on firing. Possible dark interface reaction with selenium and/or sulfur glasses (001122, 001125, 000124, 000125, 001137, 001437, 000137). 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. This full-fuse schedule effectively strikes these glasses:

Rate Temp Hold
* 1225 2:00
600 1490 :10
9999 900 **

* The initial rate of heat is not a critical factor in successfully striking gold-bearing glasses. Choose an initial rate of heat appropriate to the scale and design of the project that you are firing.

** 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.

Cold characteristics
Consistent color.

Working notes
Hues of shift colors change depending on thickness and/or lighting, regardless of whether they have been fired or not.

Expect the color to slightly shift and/or darken when firing to full fuse and casting temperatures. This subtle change compared to the unfired glass will be more apparent in thicker sections. Although true with other forms of this glass, it is most noticeable when making the thicker works for which billets were developed.

 TRANSPARENT NOTES

For each style, the top row shows the double-rolled, unfired cold glass color. For stained glass, refer to the top row.

The same glass after firing to a full fuse is shown directly below the cold glass. For kilnformed glass, refer to the bottom row.

Swatches shown are about two inches wide.

GlassTips describe ONLY the results of standard full fuse + slumping firings, i.e.: glass 6mm thick, 10" (25cm) square, fired to 1480°F (804°C), held for 10 minutes, then fired a second time to 1250°F (677°C) for 30 minutes.

To best ensure success, test glasses before use under your specific firing conditions. Use GlassTips information as a starting point only.

Glass reactivity: Not all reactions are visible. Some are too weak to be seen and others are masked by dark color.

"Striking glasses" change dramatically to reach target color during firing. Colors may vary, depending on firing schedule, rate, atmosphere, and heatwork. For color-sensitive projects, test before use.
