Unknown Floral Plate

This is a plate made by an unknown maker in the late 18th or early 19th century. I am fairly sure it is German but I could not come up with the maker as of yet. It is nicely painted with a large floral arrangement in the center and four small flowers on the fluted rim. The plate is very thinly potted and has good translucency. The surface has the look of orange skin and is not totally smooth. The piece is in great condition without chips, etc. but it has some manufacturing flaws shown in the pics on the underside. The plate is 0.875 inches tall and 8 inches in diameter. It is unmarked. Please email me for more information or other pictures.
