Hi Kirk360, welcome to the Board.
It would be helpful if you could add some photos of the floats. You do not mention any "maker marks" so are they unmarked? And what size are they?
For other readers not aware of "binary Chinese" floats, there is an article, written by a former Board member, in the Glass Museum Online, which shows a pair of fused Chinese floats in a net. Please see
