Thermal Conductivity	0.008 (DTU/(m*s))/°C
Light Absorption	20 %
Radiation Absorption	7 %
Mass per Tile	1.8 kg
Density	34.453 g/mol
Properties	Gas, Unbreathable Gas, Flammable, Toxic

Chlorine is a gas found naturally occurring in the map. It is the second highest density gas after Carbon Dioxide at the same temperature. Chlorine is a great deterrent against germs, and the best possible heat insulator among gases.

Chlorine is deadly to all germs including Food Poisoning and Slimelung. Surrounding any storage building with chlorine for a full cycle is a sure way to totally disinfect all contents of said building. A Duplicant traveling through Chlorine will not be cured of any diseases, but the surface germs on them will be subjected to the toxic gas.

As of version EX1-449549 onwards, Duplicants moving through Chlorine for more than three seconds will be hit by the Eye Irritation debuff, which reduces Athletics.

Production

• Chlorine is a renewable resource, produced by the Chlorine Gas Vent.
• Bleach Stone in its item state emits Chlorine unless pressurized (for example, by water).
• The Rust Deoxidizer produces chlorine along with its other outputs.
• It can be harvested on rocket missions to renewable Space POIs:
  • In Chlorine Clouds at a rate of 135 – 405 kg per cycle.
  • In Radioactive Gas Clouds at a rate of 9.1 – 36.4 kg per cycle.

Usage

• A Chlorine gas room is great at disinfection and heat insulation.
  • It is good for germy slime storage and processing (or any items you want to disinfect). Just remember that it takes a full cycle to destroy all germs.
  • While not perfect, it also can serve as early, more-resilient alternative to the Vacuum chamber.
  • As an insulator it is slightly worse than Insulated Tile made of Ceramic, however its low density makes it a poor buffer even when pressurized.
• The Ore Scrubber removes germs from objects and it is a way to use chlorine. However, it needs a duplicant operator, who also needs to handle the infected goods.

• The Balm Lily needs to be surrounded by chlorine and does not need any care at all. It has good synergy with Stable of Dreckos, generating infinite renewable Phosphorite.
  • Balm Lily Flower and Phosphorite dropped by Dreckos, used together produce Medical Pack, which heals Slimelung.

• Dasha Saltvine requires Chlorine atmosphere and consumes small amounts of it (6 g/s, or 3.6 kg/cycle).

• Gas Grass consumes liquid Chlorine (500 g/cycle).

• Puft Princes and Squeaky Pufts can breathe Chlorine and excrete Bleach Stone, which is consumed by Hand Sanitizers, Hot Tubs, and Waterweed.

• Failing to use excess of Chlorine, you can always pump it out into the void of Space.

Misconceptions

• For a time it was believed that deleting Germs consumes Chlorine, which is false.
  • This rumor started because Polluted Dirt off-gassed Polluted Oxygen in a one-tile box filled with Chlorine, which results in the deletion of some gas, which was incorrectly interpreted as the consumption of Chlorine. A similar phenomenon can be observed in steam chambers, as elaborated in this forum post.
