  • Publication number: 20050271820
    Abstract: A glass or other silica containing surface is masked or stenciled off randomly or in a specific pattern or design and treated with a liquid or vapor chemical composition that randomly or by specific pattern fills in the microscopic valleys and pits found in all types of glass and silica containing surfaces, imbedding that random or specific pattern (image) into or onto the substrate. As the glass or other silica containing surface is moved from a cooler ambient to a warmer ambient, condensation preferentially forms on untreated areas of the glass or other silica containing surface, leaving the treated portions substantially clear and depicting the pattern or design as a contrast difference.
