Sunflower Yellow Thin Rolled (2mm) MO

This is a Bullseye Colour that Strikes. Bullseye produces some glasses that appear pale or even colourless in their cold form but “strike" or mature to a target colour when fired to the right temperature. Stained glass and mosaic makers should beware of striking glasses. The unfired sheet colours for strikers vary widely and may not be suitable.

For Kilnformers/glass fusers some glasses appear pale or colourless and “strike" (i.e. change) to the target colour only after reheating. Keep in mind that the resulting colour may vary depending on variations in the temperature, atmosphere or amount of heat work. For example, rapidly heating Ruby Red Tint Striker (BE 1824 30F) during the initial stages of a firing cycle can prevent the glass from correctly striking and give it a blue-brown cast (the saphirine effect) as opposed to the Ruby Red colour that develops with more conservative initial rates of heat.

For projects that are especially color-sensitive, we recommend fusing or torchworking a small sample of your glass before use, to best understand the final colour result.
