Woah. Never seen either of them, but that gauge is sweet... shows you the sterilizing temperatures of the steam above the boiling point relative to the atmospheric pressure.Well, apparently i have 2 pressure vessels now lol. And the smaller one has a pressure guage. I think this might be the one to use for the first few runs. Its older but in ok condition, and has an emergency pressure relief. Looks to be about 16qt or so. Actually had this one already stashed in the metal pile at work lol.View attachment 1055825
Also that...So much knowledge in the endeavor of becoming a incoherent.
Perfect sense.Woah. Never seen either of them, but that gauge is sweet... shows you the sterilizing temperatures of the steam above the boiling point relative to the atmospheric pressure.
That's something I've had a hard time explaining to people.. that the boiling temperature of water is relative.
I took a pretty hefty dose about 2 hours ago, so that whole thing might not make sense. Words aren't wording like they usually do and it's even weirder with a phone suggesting other adjacent ones...
Yea, your boiling point is going to be 212 f at sea level with pure water.Woah. Never seen either of them, but that gauge is sweet... shows you the sterilizing temperatures of the steam above the boiling point relative to the atmospheric pressure.

Right.. that's stuff we weird people get... but taking it to laity is more like:Yea, your boiling point is going to be 212 f at sea level with pure water.
boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure.
In other mixtures of miscible compounds (components), there may be two or more components of varying volatility, (ie. alcohol and water) each having its own pure component boiling point at any given pressure. The presence of other volatile components in a mixture affects the vapor pressures and thus boiling points and dew points of all the components in the mixture. The dew point is a temperature at which a vapor condenses into a liquid. Furthermore, at any given temperature, the composition of the vapor is different from the composition of the liquid in most such cases. In order to illustrate these effects between the volatile components in a mixture, a boiling point diagram is commonly used. Distillation is a process of boiling and [usually] condensation which takes advantage of these differences in composition between liquid and vapor phases.
Also, dissolved solutes are always going to INCREASE boiling point, so as a mixture boils down, it becomes more concentrated, further increasing the boiling point.
There are a lot of different factors to learn about boiling points in relation to molecular chemistry, molar masses of dissolved substances, ect... Certainly not a terribly complex subject, but some basic principles, and lot's of maths.
Different is good, i always said it wouldnt be, but if someone puts you in a creepy zone, "more pressure different stuff creates a man like me who can see and create an outcome, just real talk, so you know, David Mykel Bruce BellRight.. that's stuff we weird people get... but taking it to laity is more like:
More pressure + different stuff = different outcome. Capiche?!

FYI, you won’t lose water (at least very very little) because it all stays in until the pressure is released. Typically, you have water up to that lower outer lip (about 3/4 inch from top) of the jar.Fired up the little pressure cooker tonight with a dry run of a 1 qt jar of water in it.
Little thing works good! The weight is kinda funny. It controls pressure by the size of the vent hole rather than weight really. Came up to 15 psi in about 45 min on the glass cooktop.
@beluga did you find you had to keep the heat at high with your glass top stove? Im not sure it will maintain pressure lower than that, though jt might. I only ran it for a few mins at 15 to pressure test it. Ill run one or 2 more trial runs before cooking grain with it.
Also how much water should I have in this thing for a 90 min run? Fill it like 2/3 up the jars? Id hate to run out of water...
I wonder how old this thing is. Made in Canada which is kinda cool and unheard of these days.View attachment 1055970
For the heat - it'd have to be on high for a while to get it up to pressure, then I'd drop it to around medium medium low to maintain 15ish psi.Fired up the little pressure cooker tonight with a dry run of a 1 qt jar of water in it.

You can purchase replacement gasket material at an automotive or hardware store, they make different thickness and materials also. I think some of the older North American units are very cheap to acquire, and well constructed, certainly the way to go on a budget.Also yeah, this little pressure cooker is awesome! lol, i totally forgot i even had it.
Its built like a tank. Super thick aluminum with a flat bottom. Only thing is the gasket doesnt look like its easily replaceable. Seems like its stuck in there good, so ill need to see if it even holds pressure.
It holds 5 quart jars perfectly, so this is for sure the one to run for my first go at this. Itll come up to pressure a lot faster for sure.
Well first try with grain jars a bust:(
All contaminated, I shall try again:)View attachment 1056183View attachment 1056184
No, I did not vent pc for 10 minutes before,So, spore syringes are inherently dirty. But that doesn't mean that direct inoculation can't work, but it's a much bigger uncertainty. I did direct inoculation for a while with some success but also a lot of green.
Couple questions, (I think you may have posted, but I suck at going back and forth on my phone):
- Did you vent your PC for 10 minutes once it had a full stream of steam?
- How long did you PC?
Your grain looks prepped quite well, but that doesn't make or prevent contamination... it had to be introduced somewhere.
Couple notes:
- Glove boxes can create a positive air pressure within them that will force stuff into your media. I would pop those gloves out and try it in the Still Air Box form. Deliberate, smooth movements so to not disturb the air much.
- Did I see that you had tape over your grain jar lids? They have to be able to release steam in order to properly sterilize, so there should be some form of air exchange.
Any extra details you can think of, I'm happy to assist in troubleshooting.
