Coal

Coal is the Factory smithy’s fuel-and-flux: the Smithy I burns one per batch where the home furnace takes Fuel. It goes into the smithy’s Iron Ingots (with an Iron Ore), Bricks, Glass, Clay Molds, Tableware, Glass Containers and Lenses.

Nobody sells it and no recipe makes it. It comes from the mine: a zombie at a Zombie Miner brings up 2 Coal and an Iron Ore each shift, and sometimes a Gem. The miner’s station comes with Zombie Mining (60 red, 10 blue), which is only revealed after you clear the way into the quarry and the mine.

Notes

  • Most of the Factory smithy runs on the mine. Without Coal it can still hammer ingots into Iron Kits, but it cannot smelt, fire bricks and glass, or make the Clay Molds its castings need.
  • In alchemy Coal carries 1 red and 2 green runes.
  • Studying it costs 2 Science and 2 Faith and gives 20 red and 10 green.
