New lids and for a short shelf life. Is there any reason not to?
PSI-pounds per square inch. The force on a cork or bottle top (aprox 1 square inch) multiplied by 7 or 8? for the huge difference in area. Ball jar lids are built to seal a negative pressure-to keep air (and bacteria) out, not in.

Yup. You'd most likely wind up with beer everywhere, and maybe shards of glass too. Besides, Mason jars are for moonshine....
Good to know. Thanks
