I was just curious if anyone successfully sterilized their WBS jars in boiling water with lid to get some pressure and higher heat?

You can get away with it...but here is what you have to do:

Boil for 1 hour, let jars sit for 1 day, repeat for three days.

The required temperature to kill the contaminants is 250?F... water boils at 212?F, so you need pressure from a pressure cooker to reach higher temperatures with water.

On my stove burner at level 6 water boils, so if I put is to ten and put a lid on it and then put a weight on the lid it should work, no?

Your jar is sealed so is now a pressure vessel, however if you are boiling it in water it will not get over 100C. If you took a sealed pressurised jar out of a PC, it may be at 120C but when you put it in boiling water it will be cooled to 100C.
You could boil a sealed jar in vegetable oil which is set at 121C which will raise the jar to 15psi inside. But you run the risk of explosion, so cheaper to spend a bit on a PC than paying the doctors to remove shards of glass from your eyeballs.

It could change your substates water content, and at the end of the day water boils short of 250?F. No matter how much you roast it all it's going to do is create a steamy atmosphere and possibly ruin your jars substrate.

The pressure would be too great if the boiling water pan's lid was held down with force it would definatley fly off and water would go everywhere :| I think the idea of the pressure cooker is that the pressure is sustained by heating up / releasing steam.

Honestly, a pressure cooker is so cheap. You dont have to get some huge one. Grab an 8qt one for 50 bucks. It will save a lot of hassle and you can be sure things are properly sterilized.

I don't mean to advacate anything illegal but im sure some close friends of yours would be more then happy to help alivate some of your expensises if you were willing to shair some of the fruits of your labour. Then you can think about buying a PC as an investment.

You can look into fractional sterilization. The first response was it in a nutshell. You soak your WBS to help germinate endospores and then boil them to kill them. You let your jars sit for another 24 hours to help germinate more endospores and then kill them. You let your jars sit again to germinate, hopefully, the last of the endospores. Then boil those off and in theory you've killed the endopores that couldn't be killed at the temperature of boiling water.

I can't vouch for the success of it first hand because I've never done it, but I've read good results on the board.

I was interested in this too. But doesn't the millet become a paste within this process?

^^^^^^^^^^^^^^^^^^^^^^
This is fractional sterilization. This is what you need to do if you don't have a PC. Fungus man has a thread where he used this method with success. This involves boiling and then letting the seeds sit and repeating the process. The idea is that each time you soak between the boils, the endospores germinate and will be killed in the subsequent boils.

The problem with your idea is that pressure won't build. As soon as the pressure does build, the lid will lift up to let out the steam. If you are stupid enough to try and force the lid down somehow, pressure will continue to build without any way to escape and something very bad will happen guaranteed. DON'T DO IT!
