Process for producing glass product

Abstract

The purpose of the present invention is to provide a process for glass product production which includes, after the step of polishing a glass using a polishing agent that contains dimanganese trioxide abrasive grains, the step of effectively removing the polishing agent which contains dimanganese trioxide abrasive grains and has adhered to the glass. The process for producing a glass product comprises a polishing step in which a glass is polished using a polishing agent that contains dimanganese trioxide abrasive grains and a cleaning step in which the glass is thereafter cleaned using a cleaning fluid, wherein the cleaning fluid is a cleaning fluid containing ascorbic acid and / or erythorbic acid.

Description

technical field [0001] The present invention relates to a method for the manufacture of glass articles. Background technique [0002] As an abrasive suitable for glass polishing, abrasive grains mainly composed of cerium oxide (hereinafter referred to as ceria abrasive grains) are widely used. However, due to the increase in the price of rare earth oxides in recent years, ceria abrasive grains cannot be obtained at the conventional cost, and therefore, researches on alternative materials thereof have been actively conducted. As alternative materials, various oxides such as zirconia or alumina have been investigated. [0003] In recent years, as abrasive grains used in glass substrate processing, it is known that dimanganese trioxide abrasive grains, which are manganese oxides, exhibit abrasive properties close to those of ceria abrasive grains, although under specific conditions. Therefore, it has attracted attention (Non-Patent Document 1). Among manganese oxides, there ...
