That's news to me (shrug)jhc said:Lol "absolutely not"? What exactly are you risking? Do the laws of nature apply to woozy bottles but not canning jars?
edit: if you read the link I posted you will see it's perfectly safe.
I would think that HFH would be fine for plastisol lined woozy caps, but not enough for sealing the "waxy/rubbery" seal on a canning jar lid. I figured there was a reason the NCHFP recommend you BWB in boiling water for a minimum of 10 minutes. That allows enough heat and time to soften up the seal on the jars. Plastisol would completely melt away at that high of a temp for that long; that's why HFH is recommended
Dunno. I'd strictly BWB in canning jars, but that's just me
