Add metals? #24
Description
How should these metals be classified?
- Tin-zinc alloy e.g. https://www.zeno.ru/showphoto.php?photo=202812
- silver washed AE e.g. https://www.zeno.ru/showphoto.php?photo=261151
It is possible these terms exist. If they do, give me advice on how I should have located them.
