Dear Lyn, Ron and David

    Thank you for your help! But unfortunatly also from you i get
    'contradictionary' answers. Two go for niello first and then gilding,
    one the other way round. Best would be to experiment myself, but this
    will be impossible with fire-gilding since it is to dangerous to the
    health. 

    David, can you explain why niello would react with mercury? 

    From someone else i understood that goldamalgam would not bond at all
    with metal sulphides. 

Thanks,
Janneke Zuyderwyk
