This incredibly rare piece of Ruba Rhombic is in amazingly good shape as this was an impractically delicate design.
Designed by Reuben Haley In 1928 after he had been inspired by the Cubist paintings he saw at the 1925 Paris Exposition Internationale des Arts Decoratifs et Industriels Modernes. ( from which we get the phrase Art Deco).
Manufactured by the Consolidated Lamp and Glass Company, Art glassware division Coraopolis, PA.
This line was very short-lived due to the difficulty in manufacturing such an angular piece using mold blown glassware.
Ruba Rhombic is so hard to find in fact that this is the second piece I’ve seen in 40 years. Therefore I was mystified by the treatment of the color application onto this particular color of glass. Finally when searching online I found that the Metropolitan Museum of Art in New York has a piece with the same appearance and coating like exterior.
I have included as the last picture the example from The Met (this pitcher is Not for Sale)
The edge of this piece does have one tiny scallop chip on the lip, I have marked this with an arrow in the second to last picture.
There may be rough spot or two from manufacturing.
The sugar bowl measures 5 1/2 inches handle to handle 3 inches deep and 2 1/2 inches tall. Please see all of the photographs as they are part of the description. See full listing on Etsy.
