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.
This method held
a pre-eminent position inglassforming ever since its introduction in the middle
of the 1st century BCuntil the late 19th century, and is still widely used
nowadays as aglassforming technique, especially for artistic purposes. The process
offree-blowing involves the blowing of short puffs of air into a molten
portionof 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
glassblob that matches the exterior skin caused by the removal of heat from
thefurnace. The glassworker can then quickly inflate the molten glass to
acoherent blob and work it into a desired shape.
