Anyone wear gloves to handle vacuum tubes?

Make sure they're cool and use cotton gloves, finger cots or surgical gloves.  The acids from your skin on hot glass can over time etch the surface making it porous causing the tube to lose vacuum.  I'm sure someone is going to dispute this, live and learn!

@faustuss ,

You are correct!

I’m totally disputing this. Since the ideal material for storing acids is glass, and highly corrosive hydrofluoric acid is about the only acid that etches glass, this is pegging my Poppycock meter to the point I had to unplug it and take an aspirin. Some manufactures literally acid etched their date codes on their tubes without stressing the integrity of the glass after decades. 🤔

They also store caustic acids in polyethylene, its not the end of the world and its not 400 degrees fahrenheit plus!
