With inversion “canning”, the cooling jars from step one are turned upside down while the contents inside them are cooling. It is still not actually canning, though, because no canning process has happened. The best you can say is that the food product has been “bottled.”
What is an upside down Mason jar?
Inversion canning is a method of canning that involves pouring hot canning materials (usually jams or jellies) into jars, securing the lid, and then turning the cans upside down on a towel for about 5 minutes. After the 5 minutes have passed, you flip the jars back upright and let them cool and (ideally) seal.

Screw on a ring and then flip the jar upside down and sit it on a rack to cool.

How do you know if Mason jar is sealed?

How long do you turn jam jars upside down?
Very quickly the jar rims are wiped down with a hot cloth and the hot lids are put on along with the bands. Invert and allow the jars to sit in this position for 30-40 minutes. When the lid does not pop, or move up and down, then the jar is sealed.
