Black Depression Glass Footed Bowl with Silver Overlay Stunning 11" Diameter by 4" tall. The actual bowl may be Westmoreland but we are not experts and this is what we were told when we purchased the item. We also guessed on the age and went with a newer piece, though it may be from the early 1900's. The silver overlay could have been applied by Rockwell or any of a number of companies who did the process. If you know more, please feel free to contact us.We have a matching vase also currently available. The piece has minor wear to the silver and no flaws noted with the glass at all. There are no identifying marks on the bottom. Cleaned with Wright's Silver Cleaner Paste, photographed and wrapped for shipping. May need to be cleaned upon receipt. Silver overlay came to its first peak in the early 1900's. There were two distinct eras of Silver Overlay. From 1895 to the early 1920's, this art had its own avid following and became a decorative rage. But during this first era, it was very labor intensive and expensive and this period was over by the mid-1930's. Glass Collector's Digest records that the cost to produce a decanter made in the early 1900's was .90 cents for the glass blank, $4 worth of silver, and $5 for the added labor for the silver overlay design. A revival of silver overlay followed immediately after WWII that lasted until the late 1950's. FREE SHIPPING TO UNITED STATES.
