A '''Bullet Furnace''' is used to smelt ore into [[metal]]. It is the most basic of the [[furnace]] buildings, with a very small capacity and a poor efficiency. You can use a Bullet Furnace to bootstrap yourself into metal production, but you're better off building a better furnace, such as a [[Compression Furnace]], as soon as you can produce or trade for the materials for one.

== Sources ==
This building becomes available after you have learned the [[Mining 2]] tech and the {{RequireSkill | Mining | 2}} skill.

Compare all [[Furnace]]s.

== Cost ==
* {{Require | 1 | Crucibles}}
* {{Require | 50 | Firebricks}}

== Use ==
*Smelt all known [[Ore]] into
** [[produces::Aluminum]]
** [[produces::Antimony]]
** [[produces::Cobalt]]
** [[produces::Copper]]
** [[produces::Gold]]
** [[produces::Iron]]
** [[produces::Lead]]
** [[produces::Magnesium]]
** [[produces::Nickel]]
** [[produces::Platinum]]
** [[produces::Tin]]
** [[produces::Zinc]]

Uses [[Charcoal]] for fuel.

== Operation ==
Can load up to 5 [[Charcoal]] which each provide 1 minutes of firing time. It is possible to load less and start the reaction and then top it up but you are still limited maximum of 5 total.

Fire and forgets recipes are 188 ore and 4 charcoal which takes approximately 3 minutes and 45 seconds, or 150 ore and 5 charcoal which takes approximately 4 minutes and 45 seconds. Either way yields 2 metal. 150/5 may be preferable if you do not have a furnace near the mine as you would be able to carry enough ore to make 6 metal.

Since fuel ticks occur on the 30 second point of each minute, if you do not mind watching your smelter, you can use the 15 second window to your advantage so that you can get 1 metal for only 1 cc. To do this, load 167 ore and 2 cc into the furnace. Fire the Bullet Furnace, and wait. you will notice your first fuel is used after it has been running for 30 seconds. The second fuel would normally be used at the 1 minute and 30 second mark. However, since your first metal will be done at 1 minute and 15 seconds, if you stop the furnace between 1:16 and 1:29, you will get both your 1 metal and 1 cc back.

== Smelting Times ==
The following section lists detailed information on the amount of time required to produce 1 or 2 metal. The amount of CC that you start with or add has no effect on the amount of time it takes. Only the amount of ore used determines time. You must provide enough CC to reach the time required.
