First read the exact item name: Polished Bronze and Bronze Detail are different materials with different blockers. The demo’s progression boundary is the most common reason Polished Bronze never appears.
Multiple community answers report that its technology sits beyond the demo’s progression cap. A missing recipe in the demo does not mean your save is broken.
Players report making Bronze Detail at the Wooden Anvil with a nearby Hardening or Quenching Bucket. The workstation areas need to overlap.
These steps come from player discussions, not an official recipe database. Launch-build names, costs, and unlocks require in-game verification.
If you are playing the Graveyard Keeper 2 demo, stop searching the visible technology tree for a hidden recipe. Players asking the same question were told that the relevant technology is outside the demo. The practical answer is to continue from the transferred save in the full game, then verify the launch-build technology tree before spending resources.
Community reports describe a two-station setup rather than a recipe at the bucket itself:
Because the available discussions use both “Hardening” and “Quenching” for the support bucket, this guide preserves that naming difference instead of declaring one universal English label. Check the wording in your current build and language.
The developer confirms that demo progress transfers into the full game. Transfer preserves your progress; it does not retroactively expose content inside the demo. After the full game is available on your platform, load the transferred save and inspect the expanded technology tree. See the release time guide if the full build has not unlocked in your region.
Not yet verified in the release build: the final Polished Bronze recipe, exact ingredient counts, the precise technology-node name and cost, workstation requirements in every language, and whether a Day-1 patch changes any of them. This page will not convert forum guesses into a fake official recipe.
