Ideal glass temperature for glass paint application.

Best results for most paints on glass are achieved when the glass temperature is at 20 degrees centigrade or above at the time of painting. In an industrial environment where large quantities of glass are being painted, some users
incorporate a warming area to raise the temperature of the glass before paint application. This assists in drying, but perfectly good results can be obtained without special equipment. While it is not essential to warm the glass before painting, it promotes homogeneous drying, and avoidance of the “skinning” effect, where the paint develops a skin preventing further evaporation of solvents.
