What does each Smithy tier cost?

Smithy I: 6× Reinforced Plank + 4× Bronze Detail + 4× Bronze Gear. Smithy II: 6× Reinforced Beam + 12× Steel Screws + 4× Engineering Details. Both sit on the furnace tab, and the second tier is a steel-era building, so it is a late-game target.

What do the four Smithy extensions add?

Bellows (4× Wooden Plank + 4× Bronze Nails + 2× Leather Scroll), Hammer (2× Wooden beam + 2× Iron Detail + 1× Iron Ingot), Press (2× Engineering Details + 4× Steel Detail + 2× Wooden beam) and Grindstone (2× Engineering Details + 4× Steel Detail + 1× Piece of stone). Costs come straight from the building data.

Which recipes belong to Smithy I and which to Smithy II?

Tier I handles the basics: Iron Ingot, Iron Kit I, Brick, Glass, Tableware and Glass Containers. Tier II repeats those and adds Clay Molds, Iron Kit II, Engineering Kit, Supply: Steel Tools and Lens — the five that need steel-era inputs.

Graveyard Keeper 2 smithy

The Smithy is the game's automated furnace tier — the conveyor line that turns ore and clay into iron, brick, glass and tableware without you standing at an anvil. Two tiers, four tool extensions, seventeen recipes between them.

Costs and research come straight from the game data, and “Where” is the work zone whose build desk offers the building — the game’s own placement record. “No research listed” means the page has none to show: either this build records none, or the game ships no name for it. In practice these rows are gated by materials, not by the tech tree.

Extensions this station accepts: Smithy: Bellows · Smithy: Hammer · Smithy: Press · Smithy: Grindstone — an extension is not decoration: the game records which station accepts it, and the recipes that need it only appear at that station once the part stands next to it.
