Pewter Signs and Symbols
An alchemist's nightmare I would think.
They are AB (Antiqued Brass) finished or AP (Antiqued Pewter) finished.
I wish the finish was always uniform. It isn't.
Sometimes the AP seems more a shiny nickel and the AB a smudgy dinge.
Pewter is not a sturdy metal. No one is building bridges out of it.
