History reference: From the "Olympic Flame" series, which was produced in a limited batch at the Gusevsky plant especially for the 1980 Olympics. Glasses and wine glasses, stylized as bowls of the Olympic flame, were made of crystal in two colors. A stable glass with an amber colored stem and a cup in the shape of the Olympic flame, symbolizing ice and flame, is decorated with hand-cut and diamond engraving, creating an interesting play of light on the crystal facets. The percentage of manual work in the manufacture of these products is maximum. An unusual play of light fluxes is achieved due to the presence of 24% lead oxide in the composition of the crystal, which in itself is a rarity in the field of crystal manufacturing technologies. This composition provides high refractive indices and dispersion. The series has not been repeated since.
