Salt or spice shaker? No inscriptions.

Anybody have any information on this...shaker? Picked it up in Pennsylvania near Valley Forge.

it won't be for salt - salt - NaCl - and silver AgCu* react chemically to form AgCl - silver chloride. silver chloride is light sensitive and goes black - the science behind one of the chemical types of photography. so you would keep the AgCu* away from the NaCl. you won't want to put much spice in there, either, as they also begin to oxidize and lose their flavours.


*even sterling has this formula, in various proportions depending on its being (800, 835, 900, 913 - not technically sterling) 925, 935 and 950
