Acid-etched glass is annealed glass treated with acid to permanently change its appearance, making it smoother than sandblasted glass. Acid-etched glass refers to annealed glass that has been treated with hydrofluoric acid to give its surface a frosted look. Thickness: 3mm 4mm 5mm 6mm 8mm 10mm Size: 1830*2440mm, 3300*2140mm acid-etched glass products offer architects and interior designers a unique opportunity to realize their design goals. Because it is not a coating, acid-etched glass maintains its look and finish over time, creating a translucent satin appearance which obscures view while maintaining a high level of light transmittance. Our full surface products come in four different opacities and can be used in interior and exterior applications.
