A Reactory is a building used to combine finished metals into alloys, using resin as a catalyst. The process also requires charcoal.

Sources

This building becomes available after you have learned the Metallurgy 1 tech.

Also, Metallurgy 1 or higher must be learned to operate an already constructed Reactory. Higher levels of Metallurgy allow increasingly more alloy types that can be crafted.

Cost

• 12 Cut Stone
• 1 Iron Pot
• 20 Leather
• 240 Firebricks
• 10 Small Topaz

Built in a Compound. Uses 18x17 cells.

Hopper Upgrades

Once a reactory is built, it may be upgraded to allow larger batches. This requires Structure Reinforcement 2 to install the upgrade, but not to use it. Upgrades must be installed in order, e.g. you must install the 2x upgrade before you can install the 4x upgrade.

An upgraded reactory allows you to choose the batch size to use when starting a new alloy. The initial charcoal, resin, metal costs, and final alloy yield are multiplied by the batch size (note: due to rounding, the yield may not be exactly scaled - see individual alloy pages for details).

The cost to reheat a large batch does not increase. It always costs 3 charcoal and 1 resin to reheat, regardless of batch size. This means that reheats are effectively cheaper for larger batches.

Upgrades Require Structure Reinforcement 2

2x Hopper Upgrade Cost

• 60 Steel Sheeting

4x Hopper Upgrade Cost

• 150 Cobalt Metal Sheeting: Hard Stainless (treated metal takes two per sheeting, so you need 300 treated Cobalt for this. Treat it first, then make it into sheeting)
• 2 Crucibles
• 10 Iron Strap
• 500 Clay Bricks
• 100 Black Raeli Tiles
• 1 Thermometer

7x Hopper Upgrade Cost

• 100 Sun Steel Metal Sheeting: Hard Stainless Insulative
• 10 Crucibles
• 10 Aluminum Strap
• 500 Clay Bricks
• 500 Firebricks
• 200 Concrete
• 250 Black Raeli Tiles
• 1 Thermometer

Use

To produce a normal-sized batch of an alloy requires an alloy-specific combination of metals and Resin, and 5 Charcoal to fuel the Reactory. Larger batch sizes in an upgraded reactory scale the required inputs according to the batch size.

An alloy must be "crystallized" by working the reactory, observing a number of rings and clicking in specific places. The yield of the reactory depends on how well this is done. See the Alloys page for more details and current theories.

After an alloy has crystallized, you have the option of either accepting the yield and taking the alloy, or reheating the batch. Reheating the batch costs 1 Resin and 3 Charcoal, and allows you to try to crystallize the alloy again for a better yield. You can repeatedly reheat a batch as many times as you like before finally taking the alloy. Note that Octec's Alloy cannot be reheated!
