    I’d probably want to spray ‘em with some kind of sealant to make them a little less porous before wearing them in lab. But I’ll be sure to watch for these at the ACS meeting!

    Good point about the sealant. Many years ago a colleague was extracting semivolatile compounds from wastewater with dichloromethane. Waste solvent was placed in a 4-L glass bottle. He had removed that bottle from the hood; as he was putting it back, the base of the bottle struck the bench and the bottom dropped out, drenching his sneaker-shod feet. He suffered no permanent damage. Having this happen with concentrated acids or bases would also be a problem.
