Le Parfait Mason Jars

Yes, Le Parfait jars are designed specifically for long-term food preservation, including water-bath canning. The wire clamp mechanism and natural rubber seal create the necessary airtight environment to keep your preserves shelf-stable.

The rubber seals are designed for a single use during the canning process to ensure a proper, sterile vacuum seal. You should replace the rubber gasket every time you process a new batch of food.

These jars are oven-safe up to 300°F. To prevent thermal shock, always place the jar in a cold oven and let it heat up gradually with the oven, rather than putting a cold jar into a preheated one.

Yes, they are freezer-safe. When freezing, be sure to leave at least an inch of headspace at the top of the jar to allow for the expansion of liquids as they freeze, which helps prevent the glass from cracking.

The wire clamps are made from durable stainless steel, which is highly resistant to rust and corrosion. However, to maintain their longevity, it is best to dry them thoroughly after washing.

Yes, the glass jars are dishwasher safe. We recommend removing the rubber seal and wire clamp before placing the glass body in the dishwasher for a more thorough clean.
