Glassblowing is a
glassforming technique that involves inflating molten glass into a bubble (or
parison), with the aid of a blowpipe (or blow tube). A person who blows glass
is called a glassblower, glassmith, or gaffer. A lampworker manipulates glass
with the use of a torch on a smaller scale, such as in producing precision
laboratory glassware out of borosilicate glass.
Mold-blowing was an
alternate glassblowing method that came after the invention of free-blowing,
during the first part of the second quarter of the 1st century AD. A glob of
molten glass is placed on the end of the blowpipe, and is then inflated into a
wooden or metal carved mold. In this way, the shape and the texture of the
bubble of glass is determined by the design on the interior of the mold rather
than the skill of the glassworker.
Free-blowing: This method held a pre-eminent position in
glassforming ever since its introduction in the middle of the 1st century BC
until the late 19th century, and is still widely used nowadays as a
glassforming technique, especially for artistic purposes. The process of
free-blowing involves the blowing of short puffs of air into a molten portion
of glass called a ‘”gather” which has been spooled at one end of the blowpipe.
This has the effect of forming an elastic skin on the interior of the glass
blob that matches the exterior skin caused by the removal of heat from the
furnace. The glassworker can then quickly inflate the molten glass to a
coherent blob and work it into a desired shape.
