More combined images of Rückl interwar decorative glass pieces, grouped by either shape, decor or usage. Note the canari (Yellow) and calrosa (Pink) shimmy pfau satin decors seen here in the 3rd down on left side, rarer color versions as well as the jade and blue. Orange shimmy pfau is quite common, see my top line of glass pieces on the Ruckl Gallery page. Also on my Home page, for Truitt's Ruckl decor line drawing catalog and the decor names.
I feel I should explain that the few documents we have from the 1920 and 1930 periods are just that, one page of glass items meant to inform and demonstrate at that moment in time, which changed as what was offered to potential customers. This is not the same type of internal confidential working diagrams, designs, measurements, decor names, and so on which Loetz collectors have the advantage of studying for instance. Ruckl is mainly based on the glass that was produced and has survived to be collected today. Because of this, it's more meaningful to collect the actual glass items, and get experience from handling them and seeing their common production aspects first hand, as well as comparing them to the other Czech glass brands and companies. That is called empirical research, the 'in hand study', not the comparison of photo shapes, colors and decors which is a minefield of inherent variations.
