To begin the process, a small amount of molten glass is gathered onto the end of a long, hollow tube called a blowpipe. The glass is then shaped by blowing air into the pipe to create a bubble, which can be further manipulated by rolling and shaping it on a flat surface or using tools to create specific designs. As the glass cools, it becomes more rigid, and additional layers of glass can be added to create a larger piece.

Glass blowing can be used to create a wide range of objects, including vases, bowls, sculptures, and even intricate glass jewelry. It requires a great deal of skill and precision, as the glass must be manipulated quickly before it cools and hardens. Glass blowers often undergo extensive training and apprenticeships to perfect their craft.

In addition to traditional glass blowing techniques, modern technology has also introduced new methods, such as lamp working, which involves using a small torch to melt and shape glass, and kiln casting, which involves heating glass in a kiln until it melts and flows into a mold.
