Argentum sulfericum

I ran across this very old bottle (cork sealed, with wax on top) of
argenticum sulfericum, or silver sulphate. I now that silversulphate is
insoluble in water. Is there any practical application for silversulphate in
alt. photo processes, or should I keep the bottle as a curious paper weigth?

Thanks,

Cor
