From the Cenedese personal collection. Here a set of 6 stem glass made in 3 different designs.
All in light fume.
This group is absolutely unique and would become the focus of a table set or make three set pairs of flute. There is a special technique, mezzo rigading, where only the lower part of the blown is ribbed, creating the effect that is typical of Cenedese and Seguso stemware.
It’s not possible to reproduce nowadays.
When not in use, they are beautiful to admire as a collector’s set.
Nothing like this exists in the market.
Listed measure is of the item on the left for reference also of the others.
One note about the fume color. Very old technique, it started as a color that would be difficult to avoid. When furnaces were working on wood fire, the partial combustion of the wood created a smoke inside the crucible, the carbon residual in the melted glass gave a light amber color that you can see on the XVII chandeliers. With Barovier formula of for the “cristallo” this coloration was resolved so the fume became a finish.
So the way to attain this color is similar to the Japanese Raku, reducing the oxigen input, the fire starts creating reducent smoke (in italian fumo/fume). The technique was then perfectionated working over other colors. Metal oxides also change the color in reducent atmosphere. Today this technique is hard to acheive with the pure burning of natural gas, so it became a way to recognise antiques.
