got a bottle of golden fluid raw umber that's been slowly solidifying in the corner of my shelf for like a year and a half. it's not fully hard yet but it's got that thick yogurt consistency where you shake it and nothing moves. i know the official answer is throw it out but i paid like $12 for this and i can still see pigment in there. part of me wants to cut the bottle open with a knife and use it like a paint cake. part of me knows that's insane.

has anyone actually done this or do we all just pretend we toss them and secretly keep a graveyard of half-dead paint bottles under the sink
