Abstract
Manufacturing method of grinding surface on glass cosmetics, in particular the nail and skin file, from flat glass of FLOAT type, is carried out by marking at least one abrasive surface on one or two sides of a glass pane or intermediate product. This surface is then coated with fusing glue, powdered with clean quartz sand with grain size between 1 and 500 μm using a sieve, and the surplus sand is knocked-down. The intermediate product with fixed sand is inserted into the fusing furnace where it is baked at the temperature of up to 900° C. The abrasive surface may be roughened by sand blasting before the fusing glue application; the intermediate product coated with fusing glue can be decorated with glass fritte.
Claims9
A method for manufacturing a glass cosmetics product, said method comprising the sequential steps of:
- (a) providing a glass substrate having first and second sides,
- (b) marking at least one intended working surface on at least one of said first and second sides of said glass substrate,
- (c) applying to at least one marked working surface a coating of a fusing fixing glue,
- (d) powdering each fusing fixing glue coating on a marked working surface with a first layer of quartz sand having grain sizes of 1-500 μm,
- (e) removing surplus quartz sand from each fusing fixing glue coating to provide an intermediate glass article with temporarily fixed quartz sand on at least one marked working surface,
- (f) inserting said intermediate glass article in a glass fusing furnace,
- (g) baking said intermediate glass article in the glass fusing furnace at a temperature up to 900° C.,
- (h) cooling said intermediate glass article, and
- (i) rinsing said intermediate glass article to provide the glass cosmetics product.
