Ice Glass

This decorative technique dates from the middle of the 16th century and is first cited in 1570 in a Venetian document.

The decorative technique involves immersing the incandescent glass attached to a blow pipe, in a bucket of water. The thermal shock produces a thick network of surface cracks. The craftsman then delicately heats the object in a furnace so that the ice-like effect keeps, while ensuring the glass wall remains intact.
