This swan shape made from black art glass is marked with the letter B inside a diamond. Manufactured by Boyd Glass and sort after by collectors it can serve multi purposes. It could be used as a salt dip, a tea light candle holder or ring holder. The slag glass has traces of other colors but is predominantly black. It is very detailed showing the feathers and a great amount of texture in the glass. Just 3 ½” long and approximately 2 ½” tall. Small but simply wonderful.
