| 99.98% lead free - 1350°FAt last, there is a very low-lead overglaze that prevents devitrification on kiln fired glass projects that is proven safe for food bearing surfaces. Super Spray will not discolor reds, oranges or other sensitive tones. For easy application, simply brush it onto your glass project or spray it on with an air brush or atomizer.Devitrification occurs in glass art during the firing process of fused glass whereby the surface of the glass develops a whitish scum, crazing, or wrinkles instead of a smooth glossy shine, as the molecules in the glass change their structure into that of crystalline solids. While this condition is normally undesired in glass art, it is possible to use devitrification as a deliberate artistic technique.By using a Devit spray this can be prevented. Simply apply before firing with a brush or spray gun, allow to dry and fire. If you have a piece of kiln worked glass that has devitrified applying devit spray and refiring can also be effective. |
