A 17cm Sun Bottle (size 2/4) in yellow/lime color (special uranium glass) in excellent condition by Finnish glass designer Helena Tynell. Uranium glass has a special color changing properties, depending on the wavelength of the light it is situated in. It can switch from pure bright yellow to neon green very warm light and back again when in shorter wavelength light. See close up photo taken under a spotlight.
Glass designer Helena Tynell is best known for her Sun Bottles (also called ‘Flower bottles’) that were produced 1964-1974 at Riihimäen lasi, in Finland.
The bottles were produced in four sizes: (4/4) is the largest, ca 32cm high; (3/4) ca 23cm; (2/4) ca 17cm and (1/4) is the smallest and most common size and is ca 12,5cm high and fits slightly over 2dl of water.
These impressive items with nice radial features are popular objects for interior decoration. They were produced in clear glass as well as in several different colors.
Our last picture shows representatives of three sizes (1/4-3/4). And the second last photo shows a mid century vase by Nanny Still that also is made of uranium glass at Riihimäen lasi.
Helena Tynell designed for Riihimäen lasi in Finland from 1946, and later moved to Germany where she designed for Limburg glass factory from 1976.
In 1986 she moved back to Finland after a long career as glass designer, and in January 2016 she passed away at 97 years of age.
