Siderale

This is a glass invented by Flavio Poli in the early 50s at the firm of Seguso Vetri d'Arte. The procedure for its preparation is as follows: a large concentric-ring murrina is made with two alternating colours; this is then heated again and applied while hot to the item being processed. After a first finishing step and after cooling, the item, still having an irregular shape, is modelled and polished at the grinding wheel: this is an extremely long and delicate operation. Using this complex and laborious technique, a limited number of item was made, very rare and refined; due to their having a quality level so high that compares well with that of northern europe.
