Cambridge Portia Five Part Elegant Depression Glass Server

Colorless etched elegant Depression glass made by Cambridge Glass, USA, circa 1932-1953. High quality heat finished table glass.

Manganese was used in place of lead (scarce during Depression years) to add strength to the glass. If clear glass glows yellow under black light, it probably dates from the early 20th century to the 1950’s. Glass with manganese will turn light purple if over-exposed to bright light for a long period of time. Cambridge used manganese until the 1950’s. They were one of the last glass makers to use it.
