Furnace
A Furnace converts ore to metal, consuming fuel.
There are two main types of furnace:
- Charcoal-fired furnaces with relatively short firing times
- large Petroleum-fired furnaces with much longer firing times but greater efficiency.
- Both produce Clinker if your Stonework level is 3 or higher, otherwise produces Strange Slag
The most time and resource-efficient CC furnace is the Gyration Cell.
| Furnace | Fuel Type | Max Ore | Fuel Req | Typical Ore:Metal | Typical Fuel:Metal | Fire Time | Typical Metal/Hour | Notes |
|---|---|---|---|---|---|---|---|---|
| Bullet Furnace | Charcoal | 200 | 5 | 100:1 | 2.5:1 | 5 minutes | FaF 188 ore + 4 charcoal = 2 metal | |
| Compression Furnace | Charcoal | 500 | 20 | 33.33:1 | 1.33:1 | 20 minutes | 45/hour | Pollution effects unclear |
| Ore Inferno Furnace | Coal | 250 | 400 | 6.58:1 | 10.52 (coal):1 | 20 minutes | 114/hour | 250 ore + 400 Coal = 38 metal. Placement requires nearby water. |
| Blast Furnace | Charcoal | 1000 | 10 | 17:1 | 0.17:1 | 10 minutes? | 324/hour FaF | FaF 991 ore + 9 cc = 54 metal |
| Gyration Cell | Charcoal | 1500 | 50 | 10:1 | 0.33:1 | 15 minutes | 600/hour | Low pollution, currently the best CC furnace |
| Fleet Furnace | Charcoal | - | 20 | - | - | 24 hours | - | Only makes Quicksilver |
| Persephone Furnace | Petroleum | 20000 | 1-1000 | 8:1 | 0.035:1 | typ. 4+ days | 26/hour | Causes heavy metal pollution in a 64 coordinate radius when opened |
| Hades Furnace | Petroleum | 20000 | 1-1000 | 6:1 | 0.06:1 | typ. 4+ days | 2k metal first 24 hrs | Seems to lower pH nearby when opened, other effects unknown |
