This lovely Blue Onion Butter Pat is a heavily potted china, with a pretty scalloped shape and good strong color. The pattern is well defined, and the pat is a little larger than most, measuring 3 1/2" across. This lovely piece was made by Cauldon, in Staffordshire, England, and has the mark used from 1905-1920. It is in excellent condition, with no damage of any kind, a really beautiful piece of Blue Onion, part of a large collection we purchased on our recent buying trip. Please be sure to click on photo for enlargement and more pictures so that you can really enjoy this lovely piece.
