-Kyle is in charge of controlling the air that enters the glass.
-John, the artist/owner is rotating the piece and shaping it with his tools.
-Rosa is shielding John's arms from the heat of the glass and helping him shape it with the wooden paddles.
-I am the door-keeper to the glory hole.
Isn't it hard to believe that a small blob of molten glass was transformed into that? Just wait until you see what it turns into when it's finished!
