Forming transparent patterns on frosted glass - using peelable adhesive mask adhered to surface before frosting treatment

摘要

Transparent designs are produced on frosted glass by masking the areas not required to be frosted by applying before treatment a peelable adhesive mask of the desired pattern, and then removing the mask after treatment and before drying. Specifically when the frosting is carried out with hydrofluoric acid an Al mask is used but when frosting is effected by spraying a coloured varnish onto the glass surface and then drying in an oven, a paper mask is used. Method is applicable to bottles, vases, etc.
