Bullseye Sheet Glass: 2mm Light Coral Striker 1205.50

This glass style requires a longer initial hold time during firing to reach the target colour - please see the working notes below. 

Contains:

Lead

May React With:

Selenium, Sulphur

Cold characteristics:

This style may not reveal (or strike to) its target colour until fired.

Transparent clear. On edge, resembles 1101.

Working Notes:

Colour usually deepens on firing. Possible dark interface reaction with selenium and/or sulphur glasses (0137, 1122, 1125, 0124, 0125, 1137, 1437). Less viscous (softer) than most other glasses. Some gold-bearing striking glasses, like this one, should be fired with a 2 hour hold at 663°C 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 colour.  This full-fuse schedule should effectively strike these glasses:

Segment 1:

Rate (°C/hr) – *

Temp (°C) – 663

Hold – 2:00

 Segment 2:

 Rate (°C/hr) –333

Temp (°C) – 810

Hold – 0:10

 Segment 3:

 Rate (°C/hr) – 999

Temp (°C) – 482

Hold – **

* 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. For colour-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 colour results.
