Chemicals

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

Selected recipe · Furnace

The source rate is 120 Chemicals 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
Synthetic Silicon	30	0.25
Wolfram Powder	90	0.75
Helium-3	30	0.25

Default source recipe: furnace:9. 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 Chemicals. 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:9`	120	0.25 Synthetic Silicon 0.75 Wolfram Powder 0.25 Helium-3	Selected default
Furnace v.2 `furnacetier2:chemicals_v2`	240	0.125 Synthetic Silicon 0.625 Wolfram Powder 0.25 Helium-3	Reference only

Worked example: plan 10 Chemicals

With no inventory, the selected recipe chain expands to the terminal resources below. The plan contains 8 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 Chemicals, before inventory
Terminal resource	Theoretical amount	Rounded gathering amount
Calcium Ore	1.458	2
Helium-3	3.75	4
Wolfram Ore	2.917	3

Already have Chemicals or any of its intermediate parts? Open this target in the inventory-aware planner to calculate the remaining budget.

Show all 8 production steps in dependency order

Theoretical production quantities; dependencies come before the items that use them.
Produce	Remaining quantity	Selected machine
Calcium Block	1.458	Smelter
Wolfram Bar	2.917	Smelter
Calcite Sheets	1.25	Fabricator
Wolfram Powder	8.75	Furnace
Calcium Powder	2.5	Furnace
Ceramics	2.5	Furnace
Synthetic Silicon	2.5	Furnace
Chemicals	10	Furnace

What uses Chemicals?

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

Supermagnet — 1 Chemicals per output item, using Furnace.
Sulphuric Acid — 1 Chemicals per output item, using Pressurizer.
Plastic — 0.2 Chemicals 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.
