Info on my vintage Edwin M Knowles covered dish

by Tiffany Pryor
(Okc, OK USA)

It is an oval covered casserole, vegetable, or soup tureen. It's white with a blue floral design (maybe roses) with decorative handles on each side and on the lid. The mark on the bottom is a large vase with the words semi vitreous printed inside and then EDWIN M KNOWLES CHINA CO. below the vase. There are no numbers or other markings to identify it by but I do know that it is early 1900's Edwin Knowles china and while I can find a few pieces from that time period online I have not found any similar pattern or dish to compare it to. I could use any information really even just the pattern name if you can help with anything at all I would truly appreciate it...Thank you, Tiffany
