About

This smelter is required to smelt the ore you mine into bars of iron.

Production of iron bars is not based on chance, instead there is a counter which, when filled to 100%, will produce a bar. Each Ore in the smelter will produce 2% of a bar on it's own, but the addition of Lime will cause EACH piece of Ore to produce an extra +1%. 25 ore in a smelter will generate 50% of a bar, but 24 ore and 1 lime will generate 72%, a substantial improvement.

Iron = Ore * (2 + Lime). (Expressed as a percentage)

Incomplete bars are carried over to the next smelting. Although a 72% batch won't give you a Bar of Iron, the second time you run the smelter filled that way, you will get one full Bar and 44% left over (72% + 72% = 144%).

The smelter must be filled with 15 charcoal in order to be lit. The smelter will then burn for 40 minutes.

Ore that could not be melted into a bar of iron will be left as Dross, which can be used as building material where one would normally need to use Stone, or as a low-value fertilizer.

• The order at which you put the lime and ore in does not matter. The picture above is just for to make it look good.
• To get the maximum amount of Iron per smelting operation, you should therefore use around 10 to 13 Lime to accompany your Ore. This way you produce Iron as quickly as possible while saving fuel.
• There is a decreasing return on your investment for adding additional Lime, so although the 1st Lime is worth 22% of a Bar, the 7th is only worth 10%. If Lime is scarce for you, you can use less without wasting too much fuel.
• If you have OCD, 20 Ore and 3 Lime will produce exactly 1 Bar of Iron with no leftovers, while using up just one single boulder. 10 Ore 8 Lime, or 5 Ore 18 Lime will also have 100% yields.
