Help! I've been trying to ID my object for years. Yesterday, flipping around on the internet, I found your site which has a 3 page educational article from research by Ellen Hill, Helen Swan and an Education Sub Committee identifying rare Ironstone "Ground" colors. The article is Additional Color on Flow Blue or Mulberry China: Polychrome, Ground Color and Gaudy-Type Decoration . Halfway down on page 3 is a piece showing as "Butterscotch" background. It is almost identical to mine. I have attached photos of my piece which includes a carved Venetian-like wooden stopper. There is a repair on the top of the bottle. The piece is Aprox 10 inches tall with cork top & 4 inches widest. With the lightweight stopper it weighs 1.5 lbs. Marked on glazed bottom "1048 M" or at least I think that is what it is. Any info would be greatly appreciated. Thanks!
