Weck Mold Jar

While the glass is durable and temperature-resistant, you should avoid extreme thermal shock. Always allow the jar to reach room temperature before placing it in a hot oven to prevent cracking.

The Weck glass lid, when used with the included rubber gasket and metal clips, creates a secure seal suitable for canning and preserving. If you are just using it for pantry storage, the lid rests on top but is not airtight without the clips.

The wide 3.875-inch opening is a major design advantage. It is large enough to fit your hand inside comfortably, making it very easy to scrub the bottom and sides thoroughly.

The glass jar itself is dishwasher safe. However, we recommend hand-washing the metal clips to prevent potential rusting over time, and the rubber gaskets should be hand-washed to maintain their elasticity.

This specific Mold Jar holds 19.6 ounces. It is a versatile mid-sized option that works well for individual portions of overnight oats, storing bulk spices, or holding small batches of homemade sauces.
