Glassblowing is a craft that involves shaping molten glass into various forms using a blowpipe. The process begins by heating glass in a furnace until it becomes liquid. The glassblower then gathers a small amount of this molten glass on the end of the blowpipe and blows into it, creating a bubble.
As the glass expands, the artist can manipulate it using tools and molds to achieve the desired shape. Once the piece is formed, it is slowly cooled in an annealer to relieve internal stresses. This technique allows for the creation of both functional items and decorative art pieces.
