I was reading the raws because I couldn't find "Efficiently make steel bars" anywhere in the crucible despite all my attempts, and it seems like it isn't included in the current release?
Heres what I found: for brass bars, it says this:
[REACTION:BRONZE_MAKING_CRUCIBLE]
[NAME:efficiently make bronze bars(3)]
[BUILDING:CRUCIBLE:CUSTOM_B][BUILDING:MAGMA_CRUCIBLE:CUSTOM_B][REAGENT:A:150:BAR:NO_SUBTYPE:METAL:TIN]
[REAGENT:B:150:BAR:NO_SUBTYPE:METAL:COPPER]
[PRODUCT:100:3:BAR:NO_SUBTYPE:METAL:BRONZE][PRODUCT_DIMENSION:150]
[PRODUCT:15:1:BAR:NO_SUBTYPE:METAL:BRONZE][PRODUCT_DIMENSION:150]
YESSLAGPIT[PRODUCT:100:1:TOOL:ITEM_TOOL_SLAG:INORGANIC:SLAG]
[FUEL]
[SKILL:SMELT]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For Steel it says this:
[REACTION:STEEL_MAKING_CRUCIBLE]
[NAME:efficiently make steel bars(3)]
[REAGENT:A:150:BAR:NO_SUBTYPE:METAL:IRON]
[REAGENT:B:150:BAR:NO_SUBTYPE:METAL:PIG_IRON]
[REAGENT:C:1:BOULDER:NO_SUBTYPE:NONE:NONE][REACTION_CLASS:FLUX]
[REAGENT:D:150:BAR:NO_SUBTYPE:COAL:NO_MATGLOSS]
[PRODUCT:100:3:BAR:NO_SUBTYPE:METAL:STEEL][PRODUCT_DIMENSION:150]
[PRODUCT:15:1:BAR:NO_SUBTYPE:METAL:STEEL][PRODUCT_DIMENSION:150]
YESSLAGPIT[PRODUCT:100:1:TOOL:ITEM_TOOL_SLAG:INORGANIC:SLAG]
[FUEL]
[SKILL:SMELT]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Notice how it doesn't have the building mentioned under steel? I think thats missing?
Edit: So I experimented a bit and figured it out. Simply add
[BUILDING:CRUCIBLE:CUSTOM_D][BUILDING:MAGMA_CRUCIBLE:CUSTOM_D]
in the missing space, I used "Custom_D" because that apparently sets the hotkey to D and that one didn't appear to be taken. Had to generate a new world to see the effect.
Also, if I am understanding the raws properly, it says "// makes 1 bar more, and 50% chance for one additional bar on top of that." for both bronze and steel, yet the raws say
[PRODUCT:100:3:BAR:NO_SUBTYPE:METAL:STEEL][PRODUCT_DIMENSION:150]
[PRODUCT:15:1:BAR:NO_SUBTYPE:METAL:STEEL][PRODUCT_DIMENSION:150]
Which I am now understanding to mean "100% chance to make 3 bars of steel, 15% chance to make 1 bar of steel." It should either be corrected to say 15% extra chance, or there is a typo and should be updated to [PRODUCT:50:1:BAR:NO_SUBTYPE:METAL:STEEL][PRODUCT_DIMENSION:150]
Sorry for poking around in your raws meph
