The issue got interesting. I havent heard about the white brass. If the scabbard was white metal, the art on both sides of the scabbard would be impossible to be created. Hardness of that material doesnt let such works and nobody would struck tughra emblem onto white metal to test and approve its grade. It has several stamps on every single piece. Here are the results of my test variations..All suggestions are welcome.
Yellowish only exist in some lower parts especially to edge of both sides,and when stratched, silver color appears below,just like the hand guard (the yellow on scabbard doesnt seem to have any oxidation unlike guard). When the silver color part is stratched, no difference appears. It continues the same color, just the material gets scratched, nothing else. When black oxidation on the silver is scratched, silver colour below.
About the guard, I know gold doesnt oxidate, but then what is it? It is a yellow homogenous layer over silver color for sure, over silver or perhaps white metal as you say. Is there anything like brass or another yellow stuff plating application known??
