A 1972 design by Frantisek Peceny for Sklo Union (made by Hermanova Hut). The design is called Dragon's Head - you can see a face in the bottom of one side of the glass. Pattern no 20235. It's a series of moulded organic shapes and ripples and bobbles, with more liner upper - see photos. Clear and heavy moulded glass vase. Becoming increasing hard to find and buy this shape, a tactile curious vase that's different in each direction.
15.5cm tall x 6.5cm widest (they came in three sizes). Weighs 600g. Circa 1970s. 
Good vintage condition with no chips. A water line internally around the middle section - you can see it within the larger globules. The glass is slightly off clear, from time of manufacture.
