I found this half-full jar of Liquitex gesso in a bin yesterday. I swear I bought it before my youngest was born. The top was crusted shut, I had to run it under hot water to get it open. Inside it's separated and a little watery on top, but I stirred it and it seemed okay? I prepped a small canvas with it just to see what happens. It feels a bit thinner than I remember but it's drying fine.

Am I going to give myself some kind of mold situation or is gesso basically immortal? I hate throwing art supplies out but I also hate painting on something that's going to fail six months from now.
