Our porcelain steel chalkboard finish offers superior color contrast, vastly improving visibility. Students can see the board from every angle in a room. This superior surface features a fine-tooth abrasive surface for easier writing with conventional chalk. The glass-hard, vitrified porcelain surface is colorfast and will not fade. Chalk is easily erased and the surface cleans with liquid ammonia-added cleaners and water. A precisely-balanced porcelain enamel ground coat is applied to both sides of the steel for a uniform, fused surface.
