Patent ID: 8065891

Claim:
A method for producing a lampshade, comprising: (1) cutting a crystal glass plate with a thickness of 4-6 mm into a plurality of strip-shaped glass sheets, then cleaning and drying said strip-shaped glass sheets, arranging said strip-shaped glass sheets in an interwoven structure in a mold, putting said strip-shaped glass sheets into a hot melting furnace and heating to 700-730° C. over a period of between 4 and 6 hours and maintaining at that temperature for 25-35 minutes so that adjacent strip-shaped glass sheets become partially attached to each other, decreasing temperature to room temperature over a period of between 24 and 48 hours to form a single-layered hot-melt glass comprising a crystal- interwoven structure; (2) placing a pair of said single-layered hot-melt glasses comprising a crystal- interwoven structure into said mold and heating to between 700 and 730° C. and maintaining at that temperature for 25-35 minutes in said hot melting furnace so that adjacent single-layered hot-melt glasses become partially attached to one other, and decreasing temperature to room temperature to form a double-layered hot-melt glass comprising a crystal- interwoven structure; (3) placing a pair of crystal glass plates filled with a mold release agent with a thickness of between 1 and 2 mm between said crystal glass plates into said mold, placing said single-layered hot-melt glass and said double-layered hot-melt glass on said crystal glass plates, raising the temperature of the furnace to between 700 and 730° C. over a period of 4 to 6 hours and maintaining at that temperature for 25-35 minutes in said hot melting furnace so that said single-layered hot-melt glass, said double-layered hot-melt glass and said crystal glass plates become partially attached to one another, and decreasing temperature to room temperature to form a triple-layered body comprising a crystal- interwoven structure; and (4) cleaning said mold agent, injecting curing gel between said crystal glass plates, and irradiating said crystal glass plates by sunlight or ultraviolet light.
