For me as GM I have halfway crafted a spell that an NPC uses to make potions or more correctly a spell that binds a spells powers in a potion. I have not fully developed the spell (I am a GM so only need guidelines), but the I have borrowed some witchcraft and alchemy into the spell.
The spell binds the powers in a potion and the end result counts as a minor artefact (with one charge). So the spell needs to supply the energy during the creation. I usually have the NPC wizard need special ingredients for the potion (blood, other essences that is fits) in order to be able to bind the spell in the potion. Just to be spectacular I usually let the wizard use a catalyst at the end that creates some smoke and a small bang
I had once (mid 90s, now lost) a whole bunch of artefact creation spells. I had (back then) a PC mage than was very good with a certain spell, so he could (with luck) get a spell description when casting it so I wrote every spell I used with a full spell description, even the spells used to bind other spells.
I don't have that nowadays (I don't even have a player that is a mage) so my lust for developing spells just in case has dropped to almost nothing. So I use only the concept of the spell (what I remember of them).
When it comes to bottles and sizes. I'm sure there are some pricelists hanging around that can be used for that.
