unscrew, dang it!
Kind of a weird inquiry here, but I need to be able to unscrew this glass jar type cover from the lightbulb, so I can change the lightbulb. But it's stuck tight on there for some reason. I've changed it out the bulb in the past but this time the cover won't unscrew off, it's stuck tight. I'm afraid to grip the glass too hard with my hand or anything for fear it will crack/break. The metal thread portion the glass screws into is just aluminum, I think. Any comments/advice appreciated.

Don't happen to have a rubber strap oil filter strap wrench.
I wonder if I was to get the aluminum really cold using that CRC Freeze-Off stuff in a spray can, if that would expand the metal a little and help it come loose. Or would it just probably contract it, even tighter?

I put on heavy gloves. I wouldn't worry about the glass jar too much as it looks to be reasonably heavy but you never know. Taking off gloves is easier than regrowing skin.

Safety glasses! You can fake a strap wrench with a leather belt but I would try a jar opener. Being old and arthritic I have a jar opener that will take jars up to 4". It was cheap and really handy.
Another option - I would ask my wife to open it for me.

Cold things contract, so unless you want it tighter, I doubt that would work. Plus you'd be likely to crack the glass from the extreme temperature change. You might try a squirt of wd40 and gloves.

Tap lightly all around with a screwdriver handle or something similar. It works on glass jars with metal lids.
