Vetreria Venier
Le travail dans le forneau

In the 14th Century, the kilns for melting glass had three floors: the first was used for heating, the second for melting, and the third for slowly cooling the manufactured items. Silica was the basic ingredient for glass, which the Venetians obtained from sand or from river pebbles. Today the furnaces are gas-fired and great care is paid to choosing the kind of glass and in its composition.
