Weck Mold Jars

Yes, Weck jars are specifically designed for home canning. Their glass lid, rubber gasket, and metal clamp system create a secure, airtight seal that is perfect for water bath processing.

Yes, these jars are freezer safe. However, be sure to leave about an inch of headspace at the top of the jar to allow for expansion as your food freezes, which helps prevent the glass from cracking.

For canning purposes, it is recommended to use a new rubber gasket each time to ensure a proper, sterile seal. If you are using the jars simply for pantry storage or refrigerator organization, the gaskets can be reused multiple times.

Yes, the jars are microwave safe. Just be sure to remove the metal clamps before placing the jar in the microwave, as metal should never be heated in the microwave.

The glass jars and glass lids are dishwasher safe. While the metal clamps can technically go in the dishwasher, we recommend hand-washing and drying them promptly to prevent any potential rust or discoloration over time.
