Regarding the date of your shards I previously indicated 1540's a a likely date for the ones you first sent. Considering your new scans I feel I now have to say thet tehse shards are not likely to have come from one single shipload any way we look at it. Most of them are from the Mid Ming period and would fit in nicely in the late 15th - early 16th century period but at least two of the above would have to be placed in the early QIng dynasty i.e. around 1700 and at least one would merit a Chenghua date i.e. late 15th century. We'll get back to this later. This information is given as an example of private conversation only and is not intended to be used as a promotion of any individual piece.
