You've confirmed hundreds of years of research right in your own kitchen!

haha i went into it expecting to lose all of them
nothing like experimenting though

One must be very careful calling a 75% failure rate prior to full colonization a 'success story'.  With a pressure cooker, one can attain a 99.9% or better success rate.  I can think of no other tool of the trade which has such a high payoff.

the "success story" was sort of meant to be sarcasm
and yes i know there's now replacement for a PC; however, sadly its not within my budget.
I'm aware 75% failure is not a success story. I was pumped that one jar made it through like a champ so i had to share

Ok, then in all seriousness;
Rinse with soap next time, then use clear water until the soap is gone.
You might even pour in enough peroxide to cover them- not so much for killing things, but to fizz up and break the bacteria and spores loose so you can rinse them away cleanly.
The cleaner your initial product is, the better your results will be.

Also, go find a PC in a thrift store or get one for free from somebody.

yeahh there wont be a next time without a PC
and trust me i've been checking thrift stores, someday i'll get one

well i made 4 half pint jars of WBS and did fractional sterilization. (steam 1 hour, wait a day, steam 1 hour, wait a day, steam one hour, wait until cool, inoculate)

Not surprising that you failed using such short times. I have pointed out many times that the tek on this site for FS is utterly useless, it COMPLETELY misses the point that people think is obvious for PC'ing. Namely that it takes a long time for the core of grains in the middle of a jar to reach temp.

The tek is transcribed direct from textbooks, the very same textbooks would tell you to PC for maybe 15-20mins, but everybody knows & accepts that this is not long enough, but for some very odd reason they cannot apply the same logic to FS. Its no wonder FS gets such a bad name, if people followed textbook advice for PC's they would have a bad name too.

When PCing it takes time to reach pressure, and time to cool down from 15psi. Many peoples jars could be subjected to steam for longer than people are doing these half assed attempts of FS. i.e. it could take 20mins to reach 15psi, and 20mins to come down to 0psi, so exposed to 40mins at 100C+ yet people will steam jars of cold grain for 30min intervals, it beggars belief. 60mins was used above, not nearly enough. The additional PC'ing time is worked out empirically by people, i.e. with a normal PC and stove it is being heated for all that time before it reaches 15psi.

It pisses me off to see so much time & effort & grains wasted by half assed attempts. Then it further discourages people from trying it out.

interesting to note and thanks for the input.

instead of fractional sterilization, if you can't afford a PC, just sterilize your grains on venus. the psi there is like 1300 or something like that.

i already tried that no luck

A small PC can be had for $20 at walmart.  If you can't afford that then how are you affording all the other supplies which add up to well more than $20?
