God, next time I get out to the army surplus place, aside from that shirt, I really need to buy one of those separatory funnels for coffee reasons. And also clean the crap out of it, because leftover glassware from gov stuff out here, you got *no* idea what was in there except it wasn't food safe. There's a reason labs still use glass! At least you *can* get it pristine, but you might need to use some other spicy chemicals to do it.
