METHOD FOR PRODUCING GLASS PRODUCT

摘要

The present invention addresses the problem of suppressing the occurrence of white cloudiness in glass and suppressing glass surface unevenness caused by a treatment step in which a functional film formed on at least one surface of chemically strengthened glass is subjected to an acid treatment to partially expose the glass. The present invention pertains to a method for producing a glass product by sequentially performing a step in which a sulfate is adhered to glass, a chemical-strengthening step in which the glass is chemically strengthened, and a treatment step in which a functional film formed on one surface of the glass is subjected to at least an acid treatment to partially expose the glass, said method also including a cleaning step in which the sulfate adhered to the glass surface is removed by means of an acid solution prior to the treatment step.
