Ahh, an unintentional consequence of a decision I made. For certain fluids in Space Age, I decided to recycle the fluid ingredient into a pre-existing item instead of making a separate solid fluid variant.
This includes molten iron and copper (recycles into iron and copper plate respectively), water (recycles into ice, of course), and holmium solution (since "solid" holmium solution would just be holmium plate); there are no other intermediates there. Honestly, holmium plate just shouldn't be recycleable, because the only recipe for "solid" holmium solution would be to "melt" back into fluid holmium solution... whose primary function is to become holmium plate for other recipes.
The only other use for holmium solution would be the electro science pack, so the only possible use case for this "solid" holmium solution would be... having made too much holmium plate out of your holmium solution, and wanting to turn it back into the fluid form... in order to reconstitute it into an electro science pack? It seems like a bit of a roundabout process...
