The Adventurer's Armory and Seekers of Secrets list a number of different types of inks.
Ink (1 oz. vial) 8 gp — CRB
The core rulebook lists one vial of ink as costing 8 gp, but doesn't give any information as to roughly how many pages of text this is good for. By and large, this doesn't matter too much because you typically subsume material costs into the costs of adding spells to a spellbook or writing a scroll.
Ink, ghost 25 gp —/20 SOS
Ghost ink from Seekers of Secrets is clear that one vial is good for one page of text.
Ink, glowing (vial) 5 gp —/15 AA
Ink, invisible (simple) 2 gp —/15 AA
Ink, invisible (average) 10 gp —/20 AA
Ink, invisible (good) 25 gp —/20 AA
Ink, invisible (superior) 75 gp —/25 AA
Glowing Ink is per vial, but it is not entirely clear how many pages the vial is good for. Given that the cost is cheaper than the regular black ink from the Core Rulebook, I'm leaning towards saying the vial is good for 1 page of text, similar to the ghost ink.
Invisible ink doesn't say if the ink is per page, per vial, or how many pages a vial of invisible ink is good for. I'm guessing that these are for single vials, like the glowing and ghost ink, and that each vial is good for one page of text.
So, issues I'm looking for clarification:
How many pages can you write with Glowing and invisible inks, and is the cost for invisible ink the cost for a single vial?
Thanks
