A customized version of this mod: https://mods.factorio.com/mod/promethium-processing by Director_K1 so all credit goes to them for the main mod.
I also removed the unneeded dependency from the mod. I generated a new red powder icon via GROK.
I changed Promethium recipe lines to no longer need constant barreled goods launched into space.
So holmium solution ingredient was changed to holmium plate
And Fluorine was changed to a lossless Fluoroketone Cold -> Hot loop requiring cooling back down, naturally.
I also changed the cost of the advanced plate research requiring many more science packs. IMHO we need more varied researches that use the promethium pack so this fits nicely, especially when paired with the Productivity Research for Everyone mod (https://mods.factorio.com/mod/ProductivityResearchForEveryone)
I realize the original author has now changed his mod to include many of the things I did to rebalance it, but I'm keeping mine as it's different in other important ways.
