Patent ID: 8307673

Claim:
A method for producing a glass lampshade, comprising the steps of: a) cutting a crystal glass plate into a plurality of crystal grains, and cleaning and drying said crystal grains; b) putting an upper crystal glass plate and a lower crystal glass plate into a mold, filling powdery aluminum hydroxide with a thickness of between 1 and 2 mm as a mold release agent between said upper crystal glass plate and said lower crystal glass plate, and arranging said crystal grains vertically and orderly on said upper crystal glass plate, said crystal grains abutting against each other and completely filling said mold; c) putting said mold into a hot melting furnace, and raising the temperature of the furnace to between 700 and 730° C. over a period of between 3 and 4 hours and maintaining that temperature for between 25 and 35 minutes whereby attaching contacting parts of adjacent crystal grains to one another and attaching contacting parts of said crystal grains and crystal glass plate to one another, and decreasing the temperature to room temperature over a period of between 24 and 48 hours to form a crystal grain hot-melt glass body; and d) taking out said glass body from said hot melting furnace, cleaning out said mold release agent, injecting curing gel between said crystal glass plates, and irradiating said crystal glass plates by sunlight or ultraviolet light.
