Glassblowing: Feel the fire
|
Until about the first century B.C., glass objects coulld only be made slowly. A single glass object could take several days to make by casting, core forming, or cutting techniques. The introduction of the glassblowing process changed all that. After this discovery, glass vessels suddenly became easy and inexpensive to produce.

 With the 20th century came an era of revolutionary technology. Machines were developed which replaced traditional mouthblowing with a semi-automatic process and transformed the craft into an industry. Classical man-made glassblowing become an art, maintaining the tradition and knowledge of ancient glassblowers.
Today's glassblower still utilizes the basic blowpipe, but now he or she might have a vast number of supplementary tools to aid in working the material. Glassblowing can be divided into several processes.
Gathering consists of capturing the glass in liquid state from the furnace.
Marvering consists of creating an even shape on the end of the blowpipe. The artist prepares the glass to blow the initial air bubble.
Blowing: The artists blows the glass to a desired size and shape.
Coloration: The artist can add additional colors and designs while reheating the glass.
In shaping the artist uses a mold to form the glass.
Annealing is the final process in which glass is cooled.
