He starts off with a small amount of glass which he gets from a cruciable that is kept continually at 2000 degrees F.
After coloring and blowing he shapes it with his tongs while rolling the pipe the glass is on
Now he hangs it a while and lets it cool a little.
He then puts it back into the furnace to heat up again, man that thing gives off some really fierce heat....
and now he twirls it while it is really hot and it gives the bowl a ribbon effect....darn clever these medieval glass blowers!
