Description from Kaufmann Mercantile

6- or 12-pack of thick sided, elegant, all-glass jars. Six sizes. Made in Germany. All replacement pieces are also available.

Weck canning jars are made with thick glass to withstand boiling, sterilizing and processing over and over again. Glass lids preclude issues with rusting, and the tab on the replaceable rubber ring, when facing downwards, indicates clearly that the seal on the jar is intact.

The point of canning is to hermetically seal the outside world from the sterilized interior of the jar, preventing the food inside from spoiling. These jars are designed to make it easy to tell whether or not this all-important seal has been made.

Boiling the filled jars (also referred to as “˜processing’) and the cooling period directly afterward, creates a vacuum seal tight enough to keep invisible microbes from entering the jar. The strength of this seal alone is also what keeps the glass lids in place. After the jars have fully cooled, the stainless steel clamps are removed and you can check if the jars have sealed by lifting the lid. If it doesn’t come off, you know for sure the jar is sealed. If the jar didn’t seal properly, you can either re-process it, or refrigerate the jar and eat the contents within a couple of days.

All jars have wide openings for tidy, easy filling. Weck jars come in round jars, cylinder jars and bottle jars. Replacement rings, lids and clamps are also available.

  • Materials : Glass, 100% natural rubber rings, stainless steel clamps
