...it's basically clear they're going to be able to get spellsilver, at this point, from the cheaper kind of ore.

The Project's acids are higher-purity, cheap to use in large quantities, they're getting the hang of smoothing out particular reaction pathways, and researchers besides Keltham now can just tell the acid molecules to please let go of their spare protons, which increases their potency by something like a factor of 10.  They're starting to develop their own tricks around magical chemistry.  Like Prestidigitating an impure chemical intermediate to react with acid, in a way where the spellsilver stays bonded after the Prestidigitation wears off and the impurities precipitate out of the solution.

Now that Keltham is thinking ahead - and he's a little ashamed about not thinking of it earlier - how does his ultra-high-Spellcraft girlfriend Carissa Sevar feel about trying something that will really stretch her magical-item-making abilities to the limit?

In particular, creating magic items that help make, not items in general like her Armillary Amulet, but particular magic items.  Manufacturing +4 Intelligence headbands, to be exact.  Unless Carissa thinks she can stretch further, to +6 Intelligence, or +4 Intelligence / +4 Wisdom.

Once they drop spellsilver cost by a factor of 10, by far the dominant cost of headbands is going to be the time and required Spellcraft of the wizards making those headbands, of which Golarion is going to need a lot.
