Identifying BREASTPLATE

[Cerjak]

[QUOTE=A Senefelder]Nando, next question, as you can see in Jeans pics the inside of his breast plate is flat ( not shiney ) rusting metal, yours is glossy ( shiney and reflects light, except where delamination has occured ( the piece that has split away is shiney, the metal underneath, is flat like Jeans ). I'm guessing that the " shiney " is either A) varnish to seal the surface, or B) and older treatment museums used to use ( I don't think they do this anymore ) a special wax. From you obsevarions, what is the treatment over the inside of the metal? I'm looking to determine which as if it is the older wax, they could sometimes get a little overzealous with it and if thick enough just might give the appearance of small delamination points ( i'm looking to as near as possible from pics make sure i'm seeing what I think i'm seeing ).

Side note, Jean got your email, will respond with a book list. Had a very busy week finishing a few things to meet completion dates.[/QUO
