Dear all,
some time ago (around 2012/2013 or so, in my first period as member of the Forum) I uploaded an inside "painted" bottle and got the following answer by the Forum (I can't find the post anymore; probably it was deleted by the admin):
"This is a photo-aided (photographic etching) bottle. The darker and blotchy areas are actually burns from some electrolytic kind of process. They also coat the inside with some color to make it look old. The inside is probably dirt or something else to made it
look like used. In some cases, they will actually put some real snuff powder in there to fool the buyer. The bottle is of a style and quality that Ma Shou Xuan would have never used, and in fact never existed until the 50s or so."
Now my question: I bought the bottle about 20 years ago, very cheap. When did the technique of photographic etching start? How expensive is/was the process?
Regards
Georges
