Well, I found a 'Fine Wellum', and quill and inkwell, and found out that they can be put in alchemy screen. Specifically quill goes to container slot and wellum (or any scroll, BTW) in right component slot. I don't know what should be put in left slot.

So is this

• some sort of reaction?
• unimplemented feature?
• just a bug?

Odd. I would expect the vellum (used for writing on) would go in the container slot.

Actually, it seems you can put any object into either of those slots. Books, rat meat, whatever. The left-hand slot will only accept reagents.
