Nah. Best way IMHO is to get a nice little airtight plug in one of those babies as a "test vessel" that you accept is going to die. Mount your CO2 hose in the airtight plug, and put the jug into a metal box or very *stout* wood that you know could handle shrapnel, or whatever it takes (though I'd imagine a metal trashcan/paint bucket would do fine).
You *SLOWLY* start to add pressure. Stop if you get to what, 30 PSI or whatever the pressure in your bottles would be. If they explode before then, you know how much pressure your design can take.
Also, even if they don't take a lot of bottle pressure, filling one up from a keg tap and then serving (or drinking) out of it would be farkin' groovin'. I'd be down for one of those just to drink out of while I blacksmith:
How much would you charge for a good porcelain jug? Both one that could stopper up and one that couldn't? I might have business for you. Private message me if you want to talk off list.
