If you pick up a
little molten glass at the end of the tube and blow into its other end, then
the glass, like a soap solution, will swell into a thin-walled ball. To someone
who will observe this work from afar, it will seem that a lighted bulb appeared
at the end of the tube. In fact, the ball is completely empty inside, but its
thin glass walls have not cooled down yet, that's why they shine like that. And
while the ball is so fiery red, it can be inflated further, giving it any
shape.

This work, which
looks like a child's play, is actually very difficult. First of all,
glassblower should be in good health. Try to blow soap bubbles for several
hours a day. And then you get tired! But molten glass is very hot. And this is
not the only point. Even the hardiest and heat-resistant person, having no
experience, will not be able to blow a glass ball. He will not know how much
liquid glass needs to be collected at the end of the tube, with what force to
blow so that the walls are of uniform thickness. He will definitely get a
curved side freak, not a ball.

| Glassblower at Work |
Imagine
a child who, a hundred years ago, watched the work of glassblowers, just as our
children look with enthusiasm at blowing soap bubbles: glassblowers move around
the stove, but without touching each other. They stick long iron pipes into the
furnace windows with an expanded end and grab some liquid glass. Then they
bring to the lips the opposite end of the tube, protected by a thick wooden
ring, and begin to blow out fireballs, continuously turning the tubes in their
hands. Who are these dashing masters? Perhaps these are fabulous trumpeter
musicians! And now, now a magical melody will burst from the swelling pieces of
flame and everything will dance, spin in a dance ...
