I'd agree with Ivo.
However, out of interest, how is the intermal part of the external decoration actually made - the bits of the scrolling design between the heavy gilded outlines? I have vase (plain blue) with perhaps the same style of decoration. Mine appears to be a lightly acid etched and frosted floral pattern which is then overlaid with the heavy gilding.
Does this ewer have the same type of work, or are the translucent sections actually a thin layer of something with the basic red-yellow blobs showing through?
