Hardening Agent

Hardening Agent is a crafting material used in multiple recipes and can be exported. It is produced in the Furnace and serves as an ingredient for components such as Lens, Liquid Helium, and Synthetic Resin. The item is intended for mid-tier production chains where hardening and stabilization are required by compound components.

Hardening Agent is obtained in the Furnace by crafting a batch from Sulphuric Acid, Synthetic Silicon, and an Applicator. The Furnace recipe consumes 5 Sulphuric Acid, 1 Synthetic Silicon, and 1 Applicator and completes in 4 seconds, producing 2 Hardening Agent per cycle.

Recipes that consume Hardening Agent include:

• Lens: requires 8 Hardening Agent, 10 Glass, and 8 Synthetic Resin; crafted in the Compounder in 12 seconds to produce 1 Lens.
• Liquid Helium: requires 1 Hardening Agent and 1 Pressurized Helium; crafted in the Compounder in 3 seconds to produce 1 Liquid Helium.
• Synthetic Resin: requires 2 Hardening Agent, 4 Sulphuric Acid, and 10 Calcite Sheets; crafted in the Compounder in 3 seconds to produce 1 Synthetic Resin.

Hardening Agent can be exported to corporations. Export data lists Future Health Solutions at corporation level 9 paying a value of 55 and offering a Compounder as the reward, and Clever Robotics at corporation level 8 paying a value of 70 and offering a Roundabout Rail Connector as the reward.

The Hardening Agent recipe itself must be unlocked in the Recipe Station under the Furnace category. Unlocking requires a Hardening Agent Blueprint (1), 300 Applicator, 800 Synthetic Silicon, 1,500 Sulphuric Acid, and 1,000 Data Points.

Practical notes:

• The Furnace produces 2 Hardening Agent per 4-second cycle; scale Furnace count to match Compounder input rates for downstream recipes.
• Synthetic Resin both consumes and is made with Hardening Agent; plan production loops to avoid bottlenecks.
• Export values differ by corporation and level; exporting to Clever Robotics yields a higher value per unit (70) than Future Health Solutions (55) and grants different rewards.
• Unlock the Hardening Agent recipe early if you intend to manufacture Lens or Synthetic Resin at scale, since the unlock costs include large quantities of raw inputs and Data Points.
