Glass is a pure compound of sand melted at a very
high temperature with the
help of catalysts.
Silicate, the main component of sand, is heated
till it is red-hot.
When it has been sufficiently
heated, it
is wound around/round a blowing pipe. Specially trained men,
who
have learnt to control their intake and output of
air, will then blow cups, bowls, vases and
bottles from the heated silicate. These men
never/cannot make
a
mistake while blowing glass, for any deviation
from
their methods could
burst their lungs or seriously
injure/harm their internal
organs. Glass makers work for years
before achieving the
status of master craftsmen. They
join the glass works from a young age,
working for a minimal pay
as apprentices. They soon
learn the trade and
become
ordinary craftsmen. With the benefit of practice and
experience, they will one
day become master craftsmen. If a particular cup or
vase requires a
special rim or design, the master craftsman will
handle it himself. Otherwise,
mass-produced glasses maybe moulded
in die casts.
