I just got done bottling my IPA in mason jars. Forced carbonated them with my buddy's legging system.
Ill advised. Though it may work on occasion, it's bound to fail. Use bottles designed to hold pressure.
Nope, not yet.
The amount of head space and the large surface exposed to air maybe a bit of an issue.
Are mason jars designed to withstand positive pressure inside? I thought canning jars hold a vacuum.

I would gladly, but it's about 8% and there are 10 16 oz jars left. And my son likes to wake up real early. But the lions play tomorrow, so that justifies it
Has anyone ever actually TESTED any of these theories? Is there any empirical evidence to support the "dangers", or is it all conjecture and/or anecdotal?
Get Savage and Hyneman on the job.
Either that, or I'll steal some of my SWMBO's canning jars and start doing it myself... ;-)
I find myself wondering "has this actually been tested?"
People on this forum have bottled in Mason Jars, let it sit for 1.5 yrs, and in the end the beer was still carbed and no explosions. I wouldn't recommend it though.

...I am definitely going to test this. grab a jar and a lid and a ring and set up a nipple on the lid that I can attach an air compressor to and start filling it... see how much pressure it will take before it shatters and/or the seal on the lid fails.
Of course, all possible safety precautions will be taken...
Hey Mythbuster,
Be really, really careful when doing such crazy experiments. Exploding glass jars with a gas is way, way more destructive than with a liquid or solid (like freezing an overfilled mason jar), since the pressure doesn't drop immediately. Gas keeps expanding until it reaches an equilibrium and that takes a lot of volume. Of course this causes shrapnel to be propelled at high velocity. If you need an illustration, there are some recent pictures on this board where a brewer had bottles explode in his shower stall and it caused a lot of property damage. Search for "boom."
You would need a very strong surrounding container to prevent glass shards flying everywhere with high velocity. An oil drum with a vented lid comes to mind, not unlike bomb squad equipment.
Let's assume for a minute that I'm not a complete idiot, kthx.
Well, I know you're not a complete idiot. You might have parts missing.
You did make me laugh with that- and of course everyone who knows you knows you're not a complete idiot. We just want you to be careful, of course! I've some accidents in brewing that remind us all to be careful, and we don't you to be one of them, that's all!
If the glass in canning jars can hold a vacuum and most canning jars are also freeze rated which causes pressure, what makes you think the glass isn't strong enough to hold carbonation. There is alot of speculation with no backup. Then everyone jumps on the person who wants to test it. Also canning jars are boiled to create pressure due to expansion then cooled as they seal to create the vacuum. So they will hold pressure.
But the lids won't. They pop off (or unseal) if there is pressure pushing out.
And yes, the jars hold some pressure (the vacuum part) but aren't designed to hold a volume of c02 like some beers and ciders. I don't know how carbed up this beer is- but if it's something like 4 volumes of c02, that could be quite dangerous.
