Hardening Agent

Check the inputs. Make a plan. Bring only what you still need.

Selected recipe · Furnace

The source rate is 30 Hardening Agent per minute. The table below converts each input rate into its theoretical cost per output item. Rates are reference ratios, not a promise about real-world completion time.

Ingredient	Input per minute	Per output item
Sulphuric Acid	60	2
Synthetic Silicon	15	0.5
Applicator	15	0.5

Default source recipe: furnace:10. Other machine tiers and alternative recipes may use different proportions. This planner selects the first default source recipe for each output.

Compare included machine tiers

This snapshot includes 2 default machine recipes for Hardening Agent. Compare each recipe's direct input-to-output proportions below. The planner and every example on this page still use the first default recipe, Furnace; this table does not change that selection or optimize the dependency chain. Explicit alternative recipes are excluded, and these rows do not establish unlock requirements, discrete craft batches, construction costs, or completion times.

Included default recipes; material amounts are per output item.
Machine	Source output/min	Direct inputs per output	Planner selection
Furnace `furnace:10`	30	2 Sulphuric Acid 0.5 Synthetic Silicon 0.5 Applicator	Selected default
Furnace v.2 `furnacetier2:6`	90	0.667 Sulphuric Acid 0.333 Synthetic Silicon 0.333 Applicator	Reference only

Worked example: plan 10 Hardening Agent

With no inventory, the selected recipe chain expands to the terminal resources below. The plan contains 16 production steps. Theoretical amounts retain fractions; the gathering column rounds each resource up once. Real craft batches may need additional inputs.

Reference resource budget for 10 Hardening Agent, before inventory
Terminal resource	Theoretical amount	Rounded gathering amount
Calcium Ore	7.5	8
Helium-3	12.5	13
Sulphur Ore	40	40
Titanium Ore	5.625	6
Wolfram Ore	6.667	7

What uses Hardening Agent?

The selected default recipes below directly consume Hardening Agent. Open an output item to inspect its complete dependency chain.

Nanosyringe — 1 Hardening Agent per output item, using Constructorizer.
Synthetic Resin — 0.5 Hardening Agent per output item, using Compounder.
Liquid Helium — 0.5 Hardening Agent per output item, using Compounder.
Lens — 3 Hardening Agent per output item, using Compounder.

Before you build

The plan combines shared ingredient demand and consumes your inventory once across all targets. Enter any finished parts you already own before collecting raw materials. Rounded gathering quantities are an allowance over theoretical ratios; actual discrete craft batches may need additional supplies.
