Don't fuck around with pressure. Even at modest pressure, if you're talking about the size of a bucket, that makes quite a bang when it lets go. Enough to cause serious injury, permanent hearing loss, etc.

The only suitable glass would be those designed for carbonated drinks. And all of those will have narrow openings precisely because they're designed to hold pressure.

A 10" opening at 10psi will have 2500 lbs. of force on it. Only an engineered product like a pressure cooker can withstand that sort of pressure at reasonable cost. Plumbing parts can also be suitable, but you need to make the joints/seals properly. It's not hard, but it's also easy to screw up if you don't know what you're doing.
