Mine is 37 cm high and weighs over two kilos. The smallest one in the third picture is 10 cm high. These vases were first produced in 1966. There color was announced in a brochure of 1967 as "elektron" blue. But they existed also in clear glass as you see. I added a double page form the Gralglas-book with som other designs by Hans Theo Baumann.
