Are mason jars safe for boiling water?
Yes, this can happen if you pour boiling water into a mason jar quickly. It is especially likely if the jar is on a hard surface such as a stove top. To avoid this, I recommend putting the mason jar on a trivet. Start by pouring no more than an inch of water in, wait a few seconds, then pour the rest.
Why turn jars upside down after canning?
The thinking behind the inverting is that the jam/jelly—being still at a temperature to destroy spoiler micro-organisms—will sterilize the underside of the sealing disc, and the little amount of air trapped under the lid. A vacuum can form if the jars are hot and the contents are at least 165 F/74 C.
