The base formula is MetalYield = Round(OreAmount*3/100) - that is for every 33.3 ore you put into the furnace you get 1 metal out. However due to the way the game rounds off this formula it is possible to get a significantly better yield by hitting the right "breakpoints".

 +
For example, a good recipe to use is 484 ore and 20 charcoal. That batch will smelt for 20 minutes and produce 15 metal. The table below shows the recipes that give the most beneficial round-off gains.

It is recommended to simply use the 484 ore + 20 cc => 15 metal recipe unless you really want to squeeze some extra mileage out of your ore at a significant increase in charcoal costs. If you want to save significantly on your ore you will have to go to the extreme recipes such as 50 ore + 20 cc => 2 metal or even 17 ore + 20 cc => 1 metal. However by using the 17 ore recipe it's possible to almost double the metal yield of the base formula by paying more than 25 times the charcoal cost.
 +
 
 +
* Many people use the 250 Ore + 20 cc = 8 Metal as a compromise between ore, charcoal and time efficiency.

This building becomes available after you have learned the Metallurgy tech.

Cost

Use

Uses Charcoal for fuel.

Operation

  • Holds up to 500 ore
  • Holds up to 20 Charcoal
  • Burns 1cc per minute for a maximum of 20 minutes

Current "fire and forget" recipes are (They take 20 minutes):

  • 117 ore, 20cc yields 4 metal,
  • 250 ore, 20cc yields 8 metal, and
  • 484 ore, 20cc yields 15 metal.

Metal Yields

The base formula is MetalYield = Round(OreAmount*3/100) - that is for every 33.3 ore you put into the furnace you get 1 metal out. However due to the way the game rounds off this formula it is possible to get a significantly better yield by hitting the right "breakpoints".

For example, a good recipe to use is 484 ore and 20 charcoal. That batch will smelt for 20 minutes and produce 15 metal. The table below shows the recipes that give the most beneficial round-off gains.

(For ore/metal and cc/metal ratios, lower is better)

125/20 take 2 less ore per metal than 500/19, but takes 4x CC and time.

Sprocket did some tests and noticed the base is 50, but can be rounded so
17/50/84/117/150/184 should all give the best results


Stoking the fire does not change the results, i.e. adding 10 cc now and 10 cc in 9 minutes is the same as adding 20 before firing.
