Acrilex 520 Black Stained Glass Enamel, 37ml, provides an intense, opaque black coverage with a glossy finish on smooth surfaces. Its self-leveling formula allows for streak-free application with a soft brush on clean glass, porcelain, earthenware, ceramic, wood, and plaster. It air dries completely in 24 hours and is widely used to create solid shadow areas and striking contrasts in decorative stained glass. It should be diluted with solvent or thinner for cleaning materials. The density of the opaque black color is essential for solid fills, graphic details, and highly elegant finishes on glass.
