I was kind of leaning there jiggaman, I've never baked to cut back on ba, only to sterilize as a final (just to be sure) after using a whatman with the oil. I usually go 5% also just to be a little cleaner. Will the BA separte and evaporate through an 18g. pin while baking? If so I'm curious at what rate? I'd hate to be taking it back out.
