Calcedonia Glass Turtle By Murano Master Dino Rosin In Keys Fine Sale

A rare Calcedonia glass turtle made by Murano master Dino Rosin is to go under the hammer in Keys Fine Art Auctioneers’ three day Fine Sale at the end of November.

The turtle, which measures approx. 48cm by 35cm and is mounted on a Calcedonia glass base, has a pre-sale estimate of £2,000-£2,500.

Born in 1948, Dino Rosin learned glassmaking as his brother Loredano’s assistant, opening his own studio in 1992 following Loredano’s death.  His works have been exhibited in many major art galleries around the world.

Calcedonia is one of the oldest and rarest forms of glass.  It was developed on Murano in the 15^th century, and is generally attributed to the master Angelo Braver whose firm was producing items in Calcedonia in 1460. 

Calcedonia glass echoes the multi-coloured strata of zoned agate, and result from a chemical process where silver reacts with minerals and other substances in the glass to create a blend of colours.

Its secrets were thought to have been lost with the fall of the Venetian Republic, but were finally rediscovered by Lorenzo Radi in 1856. Its pioneer in modern times was Loredano Rosin, working with his brother Dino, who have combined this ancient and historic glass with modern designs.

Keys Fine Art Auctioneers’ three day Fine Sale takes place on Wednesday 22^nd, Thursday 23^rd and Friday 24^th November.  Full details at www.keysauctions.co.uk.
