[RPG] Do alchemists/investigators with swift alchethe take less time to make extracts

I am pretty sure there is no canonical answer. In the Potions and Poisons player's companion, there is a page which shows what the component satchels, packs, what have you, of Alchemists from different regions might look like, but does not say they must look like this. For this reason, it seems to me that it can look like pretty much whatever you want it to look like, especially to fit with your character's background, where he's from, or even where he is now.

Personally, the first image that popped into my head was of the Alchemist throwing a small clay pot (since clay is far cheaper than glass) with a stopper. Another possibility that I just thought of is since the Alchemist uses magic to brew his extracts, he could also contain prepared bombs in fragile fields of magical energy and throw those, so he doesn't need to use (or purchase) containers for his bombs.

An 'Alchemical Item' counts as any mundane item that can be created with Craft (Alchemy). Potions count as Potions, and even though they can be made using Craft (Alchemy) they are never referred specifically as an 'Alchemical Item' anywhere in the rulebooks.

Although, Alchemist classes making potions at half-speed is not game breaking (it even makes sense!), so as a GM I would allow that as a house rule.
