Rare Large Corona Blue Enamel Roaster. This Corona Roaster was produced by The Enterprise Enamel Company of Bellaire, Ohio in 1903. The top of the roaster has a Crown and the word Corona. At the time Corona Ware was considered the most elegant line of ware made. This large Corona Roaster was also produced in a smaller size. The Enamel Roaster measures 18 3/4 inches long, 12 inches wide and 7 inches tall. It is in need of a good cleaning. I did clean it up a little but it needs much more scrubbing to bring out the beauty of it. There are a few patched spots in the bottom of the roaster and some enamel chips. This Roaster is a rare beauty.
