What Is It? December 2017


   We had several guesses for December’s What Is It? Only one reader correctly identified the objects.
   Both objects are lightning rods. The one on the upper right is recognizable by the marbling as slag glass, which is made from melted-down scrap. This ornament has the doorknob shape often used for slag balls. The frosted pink of the plain ball (bottom left) is valuable cased glass, made of one layer of clear glass over another of color. If lightning hit a rod, the glass would shatter making it easy to tell from the ground of a hit, and that the structure needs to be checked.
   Congratulations to our winner Jerry Michals of Aurora, Colorado. You have won a year’s subscription to The Mountain States Collector.
