Zusammenfassung:The invention relates to the field of glass vessels, and aims to provide a method for producing a skid resistant safe glass cup with dots. The method comprises the following steps: (a), heating glass to the temperature from 1400 DEG C to 2000 DEG C to enable the glass to become liquid glass; (b), purifying the liquid glass produced in the step (a) to be poured into a high-temperature resistant grinding tool with a plurality of circular holes of which the sizes are the same as that of the bottom of the cup, wherein the bottom parts of the circular holes of the grinding tool of the bottom of the cup are provided with a plurality of dots; (c), pouring the liquid glass produced in the step (a) into a glass tube, wherein the glass tube is made of a grinding tool sleeve tube, and the size of the glass tube is the same as the diameter of the cup opening of the cup body of the glass cup; (d), scraping the liquid glass in the circular holes of the grinding tool by a high-temperature resistant flatted scraper when the liquid glass flows uniformly to fill in the circular holes. After the glass cup is broken, when hands are used for cleaning the broken pieces, the hands cannot be punctured, and the hands are prevented from injury, so that the glass cup is especially suitable for a table board of which the table tops are provided with the dots.
