Legacy:Bar of Wrought Iron
Wrought iron, in bar form, can be used to produce a variety of medium-grade metal goods.
How to Acquire
Craft > Metal Working > Wrought Iron
Place 9 bars of Cast Iron into the Finery Forge and fuel it with 2 charcoals. After a few minutes, the cast iron left inside has a 50% chance of turning into either a bloom or slag.
At an anvil with a smithy's hammer equipped, one unit of bloom can be converted into a bar of wrought iron with a one-in-three chance. If the bloom does not become a bar of wrought iron, it instead becomes a bar of cast iron.
For a character who is neutral on the nature/industry slider, this means that the inputs to a finery forge can become the following with the stated chances:
- 1-in-2 chance of becoming slag (50%).
- 1-in-3 chance of becoming cast iron (33.3%).
- 1-in-6 chance of becoming wrought iron (16.7%).
This is after one iteration. Cast iron created this way can be used in the finery forge again with identical chances as in the first iteration. This means that after an infinite number of iterations, the chances of becoming wrought iron are: 1/6 + 1/3 * (1/6 + 1/3 * (1/6 + 1/3 * (...))) = 1/6 * (1/3^0 + 1/3^1 + 1/3^2 + ...) = .25.
