Signature on Chinese bronze incense burner

by Rudolf van Waard
(the Netherlands)

Hi Peter,
Though I know this is not porcelain I hope you can translate for me the inscription on the bottom of the incense burner, which I have copied as per attached photo.Thanks for your help.


The first character reads Bao (Treasure) the second I'm not sure. Depends on whether your rendering is accurate or not, it could be Yong (usage) or Yang (Goat), as I see it.
Peter
