The original popular Spray A has been reformulated and is now 100 percent lead-free.
It is a clear, low melting glass, ground to micron size and suspended in a medium, suitable for brush or spray application.
Spray A may be applied to fusing projects when ready for firing to prevent devitrification on the glass surface, or as an overglaze for dull or matte surfaces, or even previously devitrified surfaces. Fire to minimum 1300 degrees F (704 degrees C).
As pictured (no spray bottle is included).
