Vintage Hand Blown Glass Sock Darner End of Day Spatter Blue Yellow Pink Art

Vintage glass sock darner offers a rainbow of swirled colors. Approximately 6” long. Excellent condition. No chips or cracks. The opening at the bottom of the stem is where the tube for blowing would have been removed. Likely an “End of Day” piece made in Corning, NY. 

I have read, at the end of the glass makers day they would use the leftover glass to make items for personal use or to gift. Questions welcome. From a smoke free home.
