Basic 3.5 Alchemy Help

I know this is gonna sound amateur or possibly annoying, so I apologize but made a char that was to make a bunch of alchemists fires etc. and the way the PH puts it, it sounds like that it takes a week to make any item.

I couldn't fully understand so I'm sure I'm reading it wrong or just didn't get it, but it just feels like making smaller things like those shouldn't take that long.  Any help to clarify?
