Glass-headed pins are the result of an ingenious process: the pins are placed on a rotating wheel. Above this wheel is a rod of coloured glass, which is melted by means of a sort of blowtorch. On the rotating wheel, each pin picks up a drop of molten glass. This traditional method is the reason the pin heads are not all exactly the same size. The glass rose come from Murano, this world-reknowned city famous for the production of coloured glass.
