I ever craft some curios just because credo quests ask to. And most likely just drop them on ground, or feed to a throwawy alt... Having variable materials to curios just like to foods would be a gigantic pool of things to discover, though it'll result in an inevitable "best" combnations that will return top players to the same situation that is present currently.
This will still result to there being a small subset of good curios that you want to study, and large set of shit curios that you never study.
A better solution would be to add satiations for curiosities.
