Nice pieces, Rose but as Keith said quite modern. By the way do not use them as vases - most that have been tend to fall apart from seepage damaging the wire dividers.
That looks a nice one Keith, does it have a base mark?
I have 10 pieces 8 Japanese & 2 Chinese. The Chinese are firstly a small, very conventional vase, and secondly a modern, medium "Cinnabar" vase. I suspect the latter is actually plastic coated but I bought it anyway to remind me what the real thing looks like. Normally the underlying metal is copper/brass which tarnishes quite quickly.
The Japanese have two distinct types. Type 1 - Clear coloured glaze over beautifully beaten metal underlay with minimal wire work defining the major subject only. Type 2 - Pastel opaque background with minimal wire work defining the major subject only. Normal the exposed metal parts are plated(presumably in chrome). Several of the Japanese are marked 'Made in Japan' on the base ring. One of the Japanese ones, that I have yet to photograph is most unusual in that it rather looks like an Aboriginal dot painting and the base has a Japanese Makers Mark.
I have attached 4 samples, the two Chinese followed by an example of each type of Japanese.
