@deadlyvices @botvolution Was this the making of the extruded carbon turd. I think glasses would probably be wise, but esp an apron. While testing the turd with a student, I splashed a couple of drops of conc nitric that promptly chewed my jeans. I was wearing a lab coat at the time that makes it all the more galling. Ironically I’d just shown the student that a drop on the hand is big deal if you have running water to hand (so to speak). #riskassessment
