We scoop a small amount of glass onto a steel tube. We roll the glass over
a steel table-top, forming it into a cylinder, and we blow some air into
the glass until a bulb is created. We scoop more glass on the bulb - the
amount sufficient for forming the demanded form. We give the glass its
typical shape by pressing it against wooden sections, planks, clamping
it with various pliers, cutting it with shears and blowing the air into
it. The finished glassware is immediately put into a specially designed
furnace, where it is cooled down. The entrance temperature equals to 530
degrees Celsius. The next stage is the gradual lowering of temperature,
in order for the glass to reach ambient temperature. This allows to avoid
quenching stresses in glass that lead to glass cracking. The whole process
takes about 8-14 hours. When the process terminates, the glassware is ready for sale.
