Product Information

Bullseye transparent sheet glass is renowned for its rich colour and transmission of light. A staple of glass fusers and artists worldwide, these sheets are available in a variety of styles and sizes - able to meet the requirements of any project.

Working Notes

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.

Varies slightly from lighter to darker shade; sometimes with lighter dappling in single-rolled sheets.

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. Consult the Bullseye Annealing Chart. 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.

All our glass is COE90, Bullseye Glass compatible and suitable for applications such as glass fusing, glass casting and glass slumping (unless otherwise stated in the description).
