I'd like to know what the maximum stack sizes of the different consumable items and crafting materials in the game are. I know from experience and from this question that potions will stack up to 100, as will the various item salvaging materials. But what about gems, pages of Blacksmithing/Jewelcrafting, et al? Are these all 100 as well?
Gems stack to 30, as for the pages I have stacks of 100 each but I haven't tried having above that, but I find it unlikely they would stack above 100
Edit: Artisan pages stack to 1000
