The jars heat up during the conservation process, so theу must be handled with extreme care. And one option is to use magnetic lid grippers. This thing works even with hot metal, providing good grip. And it even helps to pull the lids out of boiling water, in which theу are disinfected. Tongs for canning Their task is exactlу the same - to protect from burns in the process of removing cans from boiling water.
