Milk glass began in Venice in the 1500s. Originally it was called Opal Glass. I've been enjoying looking at vintage Christmas ornaments made from milk glass, many from the 1940s and 1950s.
This vintage milk glass bulb is a Christmas light bulb, not an ornament.
This vintage milk glass Christmas bulb was made in the shape of a Christmas ornament.
I love these Santa and house figural milk glass ornaments!

This clown bulb cover is also a reproduction.
