Artisan Archive

What would an artisan use this for?
I've got a good supply now, but would like to tailor the marketing towards the people who would actually need it and use it.

Thanks for any insight,

Off the top of my head, I'd say medics, for making medicine, since the solid petrochems also have a potential energy rating.

However, liquid petro fuel is MORE useful to medics, since many meds require a CHEMICAL instead of merely "inorganic" to be made.
