The Venetian glassmakers on the island of Murano used the ashes of shells and seaweed (instead of wood ash) for their glass batch. The "long" glass, which remained hot longer, no longer set any limits to the imagination in the emerging Baroque period. This gave rise to playful shapes such as the "winged glasses à la facon de Venice" made with glass threads. which were soon copied all over Europe, e.g. like the original in the 17th century glass museum for the present replica.
