Thanks guys.
I was wondering does anyone know of cupric alloy beltplates or horsegear pendants like this that had niello AND tinning, instead of niello and silvering?
Niello has a higher melting temperature than tin so the tin would melt off when the niello was applied. If the niello was applied first, wouldn't it be damaged/ covered by the tinning?
And if it's silvering, the silver would probably have been applied first (higher melting temperature than niello) but the niello would have to be sanded flush with the metal surface after application, and by this the silver layer would have been damaged...
Has anyone seen a metalografic analysis of a piece (beltplate, horsegear,...) that was both covered in silver/tin and had niello decoration?
Any thoughts on this?
Vale,
Jef
