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.
Sourcing
- USA pennies after 1982 are made from zinc, and weigh either 2.5 or 3.1 grams [1].
- Zinc ingot - $3/lb. [2]
- https://www.westmarine.com/zincs-anodes
- 1-2 Ton USA sourcing. [3]
DIY
- Dripping a zince droplet from inside a penny - easy experiment with a torch and pennies. Dropping is nice and pure zinc. [4]
- Not cost effective.
- It is cost effective to use a small furnace with a steel mesh, so zinc drips out the bottom, and copper shells stay on top. - [5]
