Basics
- An element with an atomic number of 30
- Low melting temp metal (420C) which can be used for a stovetop foundry. See Stovetop Metal Casting.
- It is very useful, especially for Cathodic Protection either as a sacrificial anode, or via Galvanisation
- Some batteries use zinc
- Used in some alloys
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]
- Casting zinc rings - nice and clean just using pennies on a spoon + mold - [6]
- Melting zinc, with mini foundry - [7]
- Melting pennies on a stove is messy - [8]
