Large Furnace · Rust: Ingredients and crafting planner

Using this reference

Before gathering materials for Large Furnace, choose the recipe or variant you actually intend to make. Alternative recipes are separate shopping lists: combining their inputs would overstate the cost. The quantity you enter is the number of finished items you want, so a recipe that produces several at once may leave a small surplus.

Start with the ingredients you have the least of. A large stock of one material cannot make up for a shortage of another. The list covers the final crafting step; if an ingredient is itself crafted, open its reference separately before planning a gathering trip.

A worked example

Suppose you want 4 × Large Furnace. This recipe produces 1 per operation, so you need 4 operations. That produces 4 in total. The direct material list is Stones × 2000, Wood × 2400, and Low Grade Fuel × 300.
