This is a mystery op-shop find I picked up two years ago. Scandinavian_pieces had asked me about this candlestick see when I paired it up with a neo-dymium vase by Wirkkala a few weeks ago. The colours of the three vases shown are what attracted me: the combination of pink/mauve and blue.
The candlestick goes to two shades of blue in fluorescent light as does the Wirkkala. The Beranek vase on the right does not.
Two are sommerso and the other is not.
The candlestick has a beautifully placed bubble and a ground pontil typical of Murano makers. There are remnants of a sticker. Thanks go to Odat62 and Glasseyed for their help in attributing this candlestick to Antonio da Ros who worked for Gino Cenedese.
Wikipedia says: "Neodymium is a chemical element with the symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air. Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach. It is present in significant quantities in the ore minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a "rare earth", it is no rarer than cobalt, nickel, and copper ore, and is widely distributed in the Earth's crust. Most of the world's neodymium is mined in China.
Neodymium compounds were first commercially used as glass dyes in 1927, and they remain a popular additive in glasses. The color of neodymium compounds—due to the Nd(III) ion—is often a reddish-purple but it changes with the type of lighting, due to fluorescent effects. Some neodymium-doped glasses are also used in lasers that emit infrared light with wavelengths between 1047 and 1062 nanometers. These have been used in extremely high power applications, such as experiments in inertial confinement fusion."
