Goes without saying there are mods that kinda make calcinating flint less annoying, but would be nice to be able to put atleast a small stack (4-12) flints in a forge and blast 'em with few (2-3?) bits of coal and yield a pile o' calcined flint bits. Would be more realistic too, afaik what comes calcinating flint in real life. Alternatively crushing flint with a hammer or a pulverizer and then the pebbles go into a crucible on a campfire and get calcined through baking with coal - or allow putting the crucible on a forge (GUI for forge, anyone?).
