Oh. So basically all he does is wet the substrate to field capacity, put into jars, HEAT the water to 160 or 170F.....and that's it?

thats it.. careful not to go above 180. 155 to be safe.

but i got my shit down to a science so i keep it 160-170.

ok so the water should be covering almost the entire jar, then?

i've never used jars for pasteurized using jars.. hopefully someone with more accurate information can help ya on that though.. just a little common sense and some practice and you'll look back thinking.. "damn did i really have to ask these questions?"

yeah even ask i ask them they seem stupid, makes sense to have them fully submerged if possible, i would think. as long as the lids are tight and there are no holes on them that is..problem is, they all have holes...

thats fine.. you want steam to be able to escape.. build up of steam cant possibly be safe in a glass jar..

its okay the ask questions...

yeah but these jars are made for being closed in a pressurized system i thought. or does the external pressure in a PCer work against the internal pressure?


Is it safe to have 100% sealed canning jars in water with 170F temps? Can anyone assure me on this? That's the one thing I'm not sure about..

the internal pressure is equal with the outer pressure of the jars INSIDE the pressure cooker.. its the PRESSURE COOKER itself that is able to withstand 15 psi.. not the jars itself.

yes what im sayin is the PC has pressure which is external to the jars.

and the jars have pressure that is internal but is cancelled out by the external pressure being induced by the pressure cooker on the jars

but without pressure in the PCer and just with jars sealed heating in water in atmospheric pressure I wonder if they would explode or what...my instinct says they WOULD ......

if anyone...cough RR...who has experience with this could tell me that'd be great. I can't proceed without knowing whether or not this is safe with sealed jars

a safe bet would to just cover the jars with some foil around the top of the jar without the lid.

I just dont see the point of doing jars. Why not a big oven bag or multiple oven bags in a pot of water? Seems like jars are a total pain in the ASS compared to just a bag

here's what happens when u have unequal pressures in a sealed container...





or course.. with steam building in the inside.. it will be opposite reaction

Yeah I thought others have done this many times with good experiences though..

This entire thread has become nonsensical. Oven bags are designed, intended for high temperatures. I use them to pasteurize both in ovens, and water vats.

Reading, it seems like RR's thinking behind the jars is the small size, and no doubt the easy thermal transfer from the glass. 1 qt jars will pasteurize much, much faster than even a small 2-gallon oven bag. If you have the time to monitor and wait and don't want the effort, I'd advise using oven bags...otherwise RR's method gets the job done in what I'd expect to be the fastest overall.

i dont think this thread is absurd in anyway.. questions are being answered... at least to the best of ability. isnt that what this board is for? yes quart jars are perfect for a smaller, quicker way to get to the finish line. but like you said, oven bags do work.. i must have had a defected bag. but other than that i usually just use the spawn bags with the filter patch on them..

IMO if you want things done FAST.. you picked the wrong hobby. but yea glass is a great thermal conductor.
