As it shows various yellow areas, which are evoked by salt deposits and will keep destroying the piece, I suggest bathing it in aqua destillata and change the water every two days to finally de desalinate for two or three weeks. After employing a silver chloride test: when no bubbles arise anymore, the piced is stable and can be either conservated in a watery tannin solution or in microcrystalline wax.

Best, and thanks for sharing,
