Reply to comment by hbHPBbjvFK9w5D in Still using a 1930s pressure canner (from National Pressure Cooker Co.) that's been used by my family for 5 generations by ubermaker77

how high can the pressure become with such a system?

Mythbusters would find out for you. I miss that show.

I don't mean the limit but how high the pressure is with how you're supposed to use it. My suspicion is that this pressure cooker keeps the pressure much lower than modern ones which would be definitely a disadvantage, given pressure is what you want to have in a pressure cooker

I've only used it at 30 pounds pressure - more than enough to can what I want.

30 pounds pressure? Are you sure? That's 206 kPa, that's so high, it would be illegal in my country for safety reasons.

Those are the instructions in my recipes. Besides, they all have a safety valve. Sure, you'll spray whatever you're cooking on the ceiling, but I've never had it happen to me.
