Acid
These intermediate materials bridge raw resource extraction and finished industrial products. Their downstream use count is a source-graph planning aid, not popularity.
Plan this output ahead of projects that use it, including Copper, Glass mix, Gold ore concentrate, plus other downstream targets. Its 11 recorded downstream use(s) help reveal where one stockpile can support several goals; that is a recipe relationship, not a popularity claim.
When it fits: Add it to a project when one of its listed downstream targets is on your plan; combine quantities across those targets before choosing a production run.
The tradeoff: One source recipe run makes 12 and lists 10 Water, 2 Sulfur at Mixer; 2 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete.
