Folio

Already in place in Alchemy Lab, so you do not need to build it.

The Folio is the alchemy notebook on the desk in the tower laboratory. Open it to see two things: every alchemy result you know, with the runes it needs, and, on separate red, green and blue pages, every ingredient you have studied with the runes it carries. It is already in the laboratory when you first get there, and you cannot build another: the build desk’s entry for it is never unlocked.

Notes

It lists the runes of a result, not the ingredients you used. Use the rune pages to find ingredients that add up to it.
The 19 alchemy powders never appear on the rune pages, because they count as studied from the start, and neither do Cacao and the Firefly, which cannot be studied.
Results reach it two ways: by making them once at a Laboratory, or when a technology reveals them.
With nothing known yet it just says “Unlock New Alchemy Formulas”.
