Zinc Ingot

Zinc Ingot is a smithing material used to craft a Daniell Cell. It is forged from Calamine and Charcoal.

Crafting
Find some Calamine in the Badlands, and add to a Clay Bowl along with a piece of Charcoal. Seal the crucible with a Clay Plate and fire at a Firing Forge using Wooden Tongs. After 10 seconds, you can remove the plate, and Zinc Ingot (using right click).
