▎ 摘　　要

NOVELTY - A welded red wine glass comprises a cup body and a bottom seat which are formed by ultrasonic welding of 100 pts. wt. silicon dioxide, 1.5 pts. wt. boron oxide, 10 pts. wt. quartz, 0.1 pts. wt. plant fiber, 0.6 pts. wt. kyanite, 0.03 pts. wt. graphene, 0.05 pts. wt. nano-cobalt powder, 2.8 pts. wt. sodium carbonate, 2.6 pts. wt. nano-calcium oxide, and 0.5 pts. wt. alumina. USE - As welded red wine glass (claimed). ADVANTAGE - The welded red wine glass has an attractive appearance, quality, and without splitting; requires short time, and low energy consumption; greatly reduces production cost; and is transparent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the welded red wine glass involving forming glass cup body with suitable size and shape, forming the cup body with a bottom seat through molding, molding at 40 degrees C for 24 hours, conducting heat preservation treatment, slowly raising the temperature to 300 degrees C, at the same time, slowly raising the temperature of the cup body to be 300 degrees C, welding or ultrasonic welding through coal and oxygen at 600 degrees C, and molding.
