Burn wood into coal in a charcoal kiln, smelt copper ore and tin ore separately, and set six copper bars aside for the forge. At the forge, 2 copper + 1 tin = 1 bronze. Pick a target item first so you know when to stop mining.

2 copper + 1 tin = 1 bronze
At a roofed forge. Pick a target item first so you know when to stop mining.
Each one costs 20 stone and 5 surtling cores. With 10 cores, build both. With only 5, build the kiln, turn your wood into coal, then take the kiln apart with the hammer (you get everything back) and build the smelter.
Build on open ground beside your sheltered workbench, and leave room for the smelter’s two inputs and its output chute. A low roof over the yard causes smoke problems.

Select the Smelter’s hammer card (stone and surtling-core cost) and place it on open grass; the game’s tip then says coal fuels it and a kiln loaded with wood makes coal.
Feed ordinary wood into the kiln: one wood makes one coal. Keep fine wood and core wood in a chest so they don’t get burned. A full smelter load of 10 ore needs 20 coal, so stock up first.
Place it with the hammer within workbench range, then give it a roof; it won’t open without one. The four coal are part of the build cost. The forge doesn’t burn fuel to craft.

Carry the copper and tin bars to the forge and choose Bronze. Make only what your target needs, because some builds use copper or tin directly. Refill your coal before the next big ore run.
Once bars come out of the smelter beside the kiln and a chest, open the Forge inside a sheltered workshop; its craft list shows the Bronze x5 recipe ready to craft.
A full chest of ore does not mean the forge has usable metal. Follow the chain once with a small batch, then budget the target equipment. The starting list below includes an axe and the workshop; remove existing stations, then enter spare ore, bars and fuel as stock.
The calculator expands listed recipes only. Extra upgrade-resource entries in the newer extracted equipment data remain unresolved, so an initial-quality estimate must not be presented as a verified current upgrade budget. Check the in-game item recipe before committing the haul.
First-bronze troubleshooting by what you have

Budget check
Copper ore or tin ore
Smelt the ore using coal.
Owned ore still needs smelting fuel.
Copper and tin bars, but no forge
Reserve copper for forge construction before using it for bronze.
Include the forge as a project if it is not built.
Usable forge and both bar types
Craft bronze from the displayed recipe.
Choose one equipment target before processing the rest.
Finished bronze, but the target is absent
Check ingredient discovery, station and item requirements.
Do not gather more ore until the missing requirement is identified.
The axe needs 8 bronze. That means 16 copper and 8 tin for the alloy. Add 6 copper for a new forge: mine and smelt 22 copper ore and 8 tin ore. Including the forge’s construction cost, the reference coal budget is 64.
This is an arithmetic example from the listed recipes, for one base-quality axe and a new forge. It still needs the forge’s stone and wood, the axe’s wood and leather scraps, and the kiln/smelter building materials. Shelter pieces, spare fuel, losses and upgrades are outside that total. If you already have a forge or bars, subtract what you actually own.
It has run out of coal. Every ore needs 2 coal, so a full load of 10 ore needs 20. Top up the coal input and it carries on.
I only have five surtling cores.
Build the kiln first and turn your wood into coal. Then take the kiln apart with the hammer, which returns the cores and stone, and build the smelter with them.
Bronze doesn’t show up at the forge.
Check that the forge has a roof and that you are carrying copper bars and tin bars, not ore. If it still doesn’t appear, check the recipe’s station and discovery requirements in game.
I ran out of copper before building the forge.
The forge itself costs 6 copper bars. Smelt copper first and set those six aside before turning any into bronze.
