So I am now gradually clearing old samples, some of them 20 years old, out of the #glovebox. I had kind of assumed that they were mostly dead.
Not quite. A few grams of brown NaMeCp caught fire after 5 or 6 minutes in air. And two samples of K4Si4 went off with a flash/bang when I dropped them into a wet beaker. More are waiting. #yikes

Depressing to think of the embodied emissions, but at least no one else has to deal with the surprises in future… #chemistry #academiclife #shitejihad
