Producing method for colour painting glass

Abstract

A manufacturing method of glass mosaic plate is provided to save manufacturing time and process distinctively and express natural colors by printing on glass, breaking glass and joining broken pieces of glass by heat unlike a conventional method joining pieces of glass of regular shapes. The glass mosaic plate is manufactured by the following steps of: (i) printing on a transparent glass with glass paints; (ii) firing the printed glass at 430-640deg.C to form a marble pattern on the glass; (iii) firing firstly fired glass at 600-740deg.C for 4-10min according to thickness; (iv) quenching for 3-6min under 200-300mAq of air pressure; (v) attaching asbestos, board and cloth to one side of cooled glass plate; (vi) applying impacts on a point of the glass with a sharp tool; (vii) thermal treating the broken pieces of glass at 650-850deg.C for 15-30min to form smooth mosaic lines. The glass paints are prepared by the following the steps of: mixing one coloring-metal oxide selected from Cr2O, CaO, SeO2 and MnO with metal oxides such as SiO2, PbCrO4, B2O3 and Na2O3; firing and grinding to powder; preparing a molten material, acrylic resin, by adding resin or acryl to solvent or thinner; and mixing prepared acrylic resin with the mixed oxide powder in a ratio of 6-10 : 1.

Description

technical field [0001] The invention relates to a method for manufacturing stained glass. According to the method, after the pattern is first printed on a large-sized glass plate, the glass plate is impacted instead of assembling round or square glass blocks, which simplifies the manufacturing process and saves manpower and processing time. Background technique [0002] Coloring of various graphics is usually achieved by dyeing the glass surface. Therefore, the method is widely used to decorate interior spaces, glass walls of buildings, various glass doors, and the like. [0003] There are currently several methods of making stained glass. One way is to cut colored glass into special shapes and fit them together. Another method is to paint the formed glass and attach the printed celluloid to the surface of the glass plate. [0004] The method of drawing figures or patterns will be described below. That is, using high-viscosity epoxy resin to draw a pattern outline on gl...
