Anchor Hocking Canning Jars

Yes, their thick-walled glass construction is specifically designed to withstand the heat and pressure required for safe home canning.

Absolutely. The glass is freezer-safe, making them excellent for storing small batches of sauces, stocks, or leftovers. Just be sure to leave a little headspace at the top to allow for expansion as the contents freeze.

The glass jars are naturally non-reactive and non-toxic. The two-piece metal lids are designed for a secure, airtight seal, but if you are strictly avoiding all plastics, note that the underside of the lid typically features a food-safe plastisol liner to ensure that airtight seal.

Yes, they are microwave safe. However, always remove the metal lid before heating, as metal should never be placed in the microwave.

No. Unlike plastic containers, high-quality glass is non-porous, meaning it will not retain odors, flavors, or colors from previous contents, keeping your food fresh and pure.

The metal rings are reusable indefinitely, but the flat sealing lids are generally intended for single use during the canning process to ensure a reliable vacuum seal. If you are using the jars for general pantry storage rather than canning, you can reuse the lids as long as they remain in good condition and seal properly.
