This small bump, called "glass drop" in the production of professional terms, after the complete molding, cut off the tail part of the excess glass solution, is a feature of the glass before the manual furnace. At the same time, leaving the mouth at the mouth of the cup can also prevent the perfect connection between the glass fittings. For example, the heat-resistant glass tea set will be heated frequently, if the parts are properly sucked together, the inside of the pot during the heating process High air pressure cannot be released, and it is very likely that danger will occur after the internal and external air pressure difference reaches a certain level. Glass drops are normal and present on all hand-blown glassware and are an important feature of the naked eye distinguishing between handmade glass and mechanical glassware. (Note: Blowing process: using a long iron pipe to draw a glass blank that has been melted by a high temperature of 1200 degrees, the glass craftsman blows the uncooled billet at the other end of the iron pipe to make the glass blank swell and form a shape The first formed bottom is first hardened. At this time, the glass at the position of the spout is not completely solidified. The craftsman uses a knife to gently cut along the preset position to separate the entire cup from the remaining glass blank on the long iron tube to form a cup mouth. And thus a slight ball joint bulge is formed at the mouth of the cup. Origin / manufacturing methods MSA GLASS ENGRAVING
