Explosives crafts 1 per batch at workbench level 3.
Furnace stage
Ore, fuel, and smelt time
- Ore to smelt
- 960
- Smelt time
- 1m 10s
- Wood for fuel
- 7
- Charcoal returned

| Refined output | Amount | Ore | Ore units | Time |
|---|---|---|---|---|
 Sulfur | 880 | Sulfur Ore | 880 | 59s |
 Metal Fragments | 80 | Metal Ore | 80 | 11s |
Charcoal runs 1,199 short of what the recipe needs, so about 4,796 extra wood has to be burned to top it up.

Raw resources and nodes to farm
| Resource | Total | Yield / node | Nodes to farm |

 Wood | 4,803 | ≈ 17 trees | |
 Sulfur Ore | 880 | ≈ 2 sulfur nodes | |
 Metal Ore | 80 | ≈ 1 metal node | |
 Animal Fat | 18 | ≈ 1 animal | |
 Cloth | 6 | ≈ 1 hemp plant |
Yield per node is an editable estimate. Adjust it to match your server multiplier and tool tier; the node counts recalculate as you type.

Quick answers
Frequently asked questions
How much sulfur does it take to craft C4 in Rust?
A single Timed Explosive Charge needs 2,200 sulfur once the gunpowder and explosives underneath it are expanded. Set the target to C4 and a quantity to see the running total for a full raid load.
Does the planner count furnace time and wood?
Yes. Any raw material that comes from ore is routed through the furnace you pick. The tool sums the ore to smelt, the wood burned, and the charcoal that comes back as a byproduct before crafting begins.
Where do the node counts come from?
Yield per node is a planning average you can edit to match your server rate and tools. The gather figures then divide the raw total by the yield you set, so the node count reflects your own farm.
Is crafting time affected by my server?
Craft and smelt time both scale with the craft and gather rates saved in your wipe profile, so a modded server shows shorter times than a vanilla one.
