Monster dome glass with light clear swirling. These clear swirls might turn purple under some sunlight??? Just a guess by me but back to this beautiful piece of glass. Sparkling ice aqua CD 151 H.G.CO. PATD MAY 2ND 1893 R- PETTICOAT. As far as condition this is the best I have ever seen in a ice aqua. All drips are PERFECT!! Just two paperthin half matchhead size skirt edge mold removal flecks from MINT. A unique piece for sure!!! $ 110.00 and that includes shipping.
