Ruby glass is the dark red color of the precious gemstone known as a ruby. It was a popular Victorian color that never went completely out of style. The glass was shaped by many different processes to make many different types of ruby glass. There was a revival of interest in the 1940s when modern-shaped ruby table glassware became fashionable. Sometimes the red color is added to clear glass by a process called flashing or staining. Flashed glass is clear glass dipped in a colored glass, then pressed or cut. Stained glass has color painted on a clear glass. Then it is refired so the stain fuses with the glass. Pieces of glass colored in this way are indicated by the word stained in the description. Paden City Glass Manufacturing Company was well-known for its ruby glass. Related items may be found in other categories, such as Cranberry Glass, Pressed Glass, and Souvenir.
