Clessidra (Hourglass) is a classic of the brand leader in modeling for art glass Venini by Paolo Venini and Fulvio Bianconi in 1957. The hourglasses are available in many colors. Clessidra is a piece of furniture from the old charm but exceptionally contemporary. Realized with the technique dell'incalmo, a very complex machining which consists of coupling two hot blown forms, along their circumference, so as to obtain a same object in different areas, and usually of different color. Available colors STRAW YELLOW/RED, APPLE GREEN/STRAW YELLOW or TAUPE/ACQUAMARINE.
