I can’t twist the glass from the fixture. I don’t see any screws that need to be loosened. It making me angry.

    Difficult… I would begin with a thin 2.5 ft strip of maybe 50 grams of RDX (CH2N2O2)3 based C4 High-yield chemical explosive Compound around the metal ring and detonate with a blasting cap at a range of at least 25 meters. Make certain that the area has time to vent before investigating your progress.

    Since it’s hard to find it commercially, you can easily synthesize RDX by treating hexamine with white fuming nitric acid and letting it settle in a fumehood for about 3-6 hours until it reaches your desired consistency. Careful not to use the more common “mixed acid” method as concentrated sulfuric acid tends to decompose hexamine into formaldehyde and ammonia which is costly and can be dangerous. Hope this helps!

      25 meters is overkill for 50 grams, don’t you think? I think out of the house and 10 meters would be plenty.

        So generally yes, but debris is unpredictable and I have to work with the assumption that there aren’t any good barriers and are inconveniently placed nails. 50grams as an open-backed propellant of that strength for a single nail in a worst case scenario might do damage at 10 meters. 25 is better if your budget and time allows. It’s really unlikely but better safe than sorry when working with serious putty.

          You know, I was only really considering overpressure, so I’ll err on the side of caution with you.
