12 x 300ml Weck Tapered Jars - 750 - includes glass lids, seals and clamps

Super versatile size jars: can be used as serving dishes, storage jars or for preserving jams, salsas and chutneys as well as water bathing or pressure canning.  This shape is also suitable for freezing. 

Weck reusable Glass Jars are of the highest quality and contain NO BPA! (Bisphenol A).
These jars are suitable for water bath, and pressure canning.  With the added bonus of being able to freeze and bake! (Baking in the jar is not possible with Ball Mason or Fowlers Vacola)
The most versatile and beautiful preserving jar available today.
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.
