The present bottle was made by rolling fragments of colored glass into clear glass in the blowing process. The fragments are melted by the heat of the colorless glass and as the form is blown the molten fragments are intentionally twisted and stretched to produce the random pattern.
When glass raw material is produced it tends to contain air bubbles. These could be eliminated and for glass imitating various precious hardstones, the glassworks went to considerable trouble to do so. They could also be exaggerated by stirring air into the molten glass mix, or by manipulating the gather of glass on the blow-iron to introduce air bubbles. Qing Chinese glassmakers frequently used air bubbles as a feature of their products, as is obviously the case here, where the maker has made positive use of some unusually large bubbles and of extended patterns of smaller ones.
