Zinc

Intro

• Low melting temp metal (420C) which can be used for a stovetop foundry. See Stovetop Metal Casting.
• It is very useful: as a sacrificial anode for marine/costal applications this is invaluable, also cars up north with the salted roads are typically galvanized, or electroplated with molten zinc, also some batteries use zinc.
