Mods introducing new content into the game.
Version: 0.9.3
Date: 2025-10-26
Compatibility:
- Maraxsis sand refining time now follows item merged with K2/K2SO (https://mods.factorio.com/mod/promethium-quality/discussion/68fd402c1630a61d2a97dbb8)
Version: 0.9.2
Date: 2025-06-12
Graphics:
- Added frozen patch for Refinery
Version: 0.9.1
Date: 2025-06-11
Bugfixes:
- Fixed use after invalid when checking to set quality blacklist on new inserters
Version: 0.9.0
Date: 2025-06-09
Features:
- Refining recipe is now shown in Factoriopedia alongside "Recycling recipes"
- Added per-user setting "Blacklist highest quality on input", enabled by default
Balancing:
- Promethium chunks no longer spoil by default. Existing saves should not be affected and related setting is still there. Purpose is to align mod out-of-the-box as content-only, rather than unwittingly tweak approaching promethium science
Changes:
- Explanation behind using promethium now has a more realistic, scientific background
- Promethium emulsion recipes now sit alongside advanced thruster fuel/oxidizer
- Tree seed and pipe to ground can no longer be refined
Bugfixes:
- Fixed audible distance modifier on refinery sounds
- Fixed cargo / fluid wagon refining generating when quality does not give bonus
Version: 0.8.19
Date: 2025-04-15
Changes:
- Disabled refining on many more items on which quality has no effect
- Graphics for Refinery have been updated, though there should be no obvious changes
- Icon for Promethium chunk melting has been updated
- Refinery now filters for Promethium emulsion, it should be more intuitive
Bugfixes:
- Fixed settings "Debug refining graph" and "Allow quality effect on Refinery" not being read properly
Version: 0.8.18
Date: 2025-02-22
Bugfixes:
- Fixed startup setting "Refining time maximum (min)" not being properly applied
Version: 0.8.17
Date: 2025-02-22
Features:
- Refinery can now be circuit connected. Requires Factorio 2.0.35
Minor Features:
- Added startup setting "Refining time maximum (min)", disabled by default (https://mods.factorio.com/mod/promethium-quality/discussion/679b093fa8a1d84739770001)
- Added startup setting "Allow quality effect on Refinery", disabled by default (https://mods.factorio.com/mod/promethium-quality/discussion/67ac5822766e0fe88de264d5)
Version: 0.8.16
Date: 2025-02-07
Features:
- The mod now takes into account spoil results of items (https://mods.factorio.com/mod/promethium-quality/discussion/679b093fa8a1d84739770001)
Balancing:
- Maraxsis sand now has sane refine time (https://mods.factorio.com/mod/promethium-quality/discussion/679b093fa8a1d84739770001)
Changes:
- Automated insertion limit for refining recipes that take 3+ minutes, is now forced to be 1 (https://mods.factorio.com/mod/promethium-quality/discussion/679e747299654add68a35c7d)
Version: 0.8.15
Date: 2025-01-19
Features:
- Added startup settings that modify refining time, for those who want it easier or harder
Version: 0.8.14
Date: 2025-01-16
Bugfixes:
- Fixed crash when incorporating modded smelting recipe
Version: 0.8.13
Date: 2025-01-11
Features:
- Added startup setting to change promethium chunk spoil time. May also be turned off by setting to zero
Version: 0.8.12
Date: 2025-01-05
Locale:
- Fixed Refinery's tooltips on item input not showing
Version: 0.8.11
Date: 2025-01-05
Bugfixes:
- Fixed flaw in refining time calculation logic that could make items referenced by looping recipes not refinable. This fixes Maraxsis compatibility for carbon fiber (https://mods.factorio.com/mod/promethium-quality/discussion/6778a764a4b563f1270adeb7)
Version: 0.8.10
Date: 2025-01-04
Minor Features:
- Added startup setting "Debug refining graph" allowing you to, albeit very verbosely, check why a specific item is not refinable
Version: 0.8.9
Date: 2025-01-04
Bugfixes:
- Even though mod load should ensure this doesn't happen, signal the Quality mod that refining recipes should not be used for recycling recipes. This might fix https://mods.factorio.com/mod/promethium-quality/discussion/677839138b4762a1103ca529
Version: 0.8.8
Date: 2024-12-31
Bugfixes:
- Fixed crash attempting to autoset refining time from "thin air" recipes when there are no results defined
Version: 0.8.7
Date: 2024-12-30
Info:
- Specified features required in info.json to show Space Age DLC requirement
Version: 0.8.6
Date: 2024-12-30
Features:
- The mod now generates refining recipes for items that are derived only from fluids
Balancing:
- Refining time calculation now prefers walking through production chain that has the least amount of fluids. This fixes base alternate recipes involving molten iron/copper being picked
Bugfixes:
- Fixed possible crashes where recipes with energy_required as nil get wrongly picked up
- Fixed plastic bar and ice having absurdly low refining time
- Fixed solid fuel, scrap and uranium ore being able to be refined
- Fixed refining time for base items getting set more than once
Version: 0.8.5
Date: 2024-12-29
Bugfixes:
- Fixed plates coming from smelting recipes improperly having double the refining time they're supposed to
- Fixed Lithium reverting back to autogenerated refining time
Version: 0.8.4
Date: 2024-12-29
Features:

- All modded science packs now have a default refining time of 5 seconds
- Modded smelting recipes now contribute to overall end product refining time
- Other mods can now opt-out or set their own complexity for an item
Changes:
- Mod should no longer crash on startup when it sees an incompatible circular dependency
Balancing:
- Probabilities are now considered when calculating refining time
- Wood can now be refined
- Refining time for ammo has changed, since it's now automatically generated
- The mod will now also artificially inflate any new modded ammo items

Version: 0.8.1
Date: 2024-12-28
