Producing method for safety glass cup

The invention relates to the field of glassware and aims to provide a producing method for a safety glass cup. The producing method comprises the following steps of a, heating glass to 1,500-2,000DEG C and enabling the glass to be changed into liquid; b, performing impurity removal on molten glass obtained in the step a and then pouring the molten glass into a high-temperature-resisting grinding tool containing a plurality of holes with the same sizes as the cup bottom sizes; c, pouring the molten glass obtained in the step a into a grinding tool casing pipe to obtain a glass tube with the diameter size of a cup mouth of a glass cup body; d, completely scraping the molten glass at hole openings in the grinding tool in the step b by using a high-temperature-resisting flat plate scraper when the molten glass uniformly flows to fill the holes; e, cutting the glass tube prepared by the step c into the length size required by the cup body, and sticking a layer of high-temperature-resisting explosion-proof membrane on the outer wall of the glass tube. After the glass cup is broken, hands are prevented from being punctured when broken pieces are swept, the injury is avoided, and labor cost is reduced.
