Trying to find out more about this recent purchase. The shape looks very Chinese, and, at first glance, so does the decoration. However, on closer inspection it appears to be an underglaze transfer print which would be unusual for a Chinese piece.
The paste is quite whitish but with several small black and brown specks in it. The vase has a pale green glaze, then has been decorated with a matt black glaze over the top, with the decorated portions showing through. The vase appears to have some age: it's slightly wonky and shows plenty of wear. The green glaze also shows quite a bit of iridescence, especially where it borders the black glaze.
So far I'm a bit stumped as to origin. The shape looks very Qing dy Chinese, but, in terms of technique, the decoration does not. I'm now wondering if it might be a European piece in a Chinese style, or possibly a Chinese vase which has been clobbered. The Gotheborg site also mentions that transfers were used on Chinese porcelain for a brief period in the early 20th century so perhaps that is another option, though I have some doubts about the paste and foot finish.
If anyone has any ideas, I'd be grateful to hear them!
Thanks
Steven
