Glass beads, how were they made?

The making of glass beads and the tools used have not changed much in a thousand years, of course modern versions of them are used but the function has remained the same. The craftsman needs a small furnace and a bellows to achieve temperatures of over 1000 ℃. A "dorn" is a round metal rod around which the hot glass can be wrapped or pulled over, there are archaeological finds from Helgö of mandrels with handles. The finds made on mandrels often have a conical tip for easier removal of the finished pearl.
