Glass Jar WECK Quadro 290 ml set of 6

WECK Quadro 290 ml glass jars, pack of 6, are designed for safe and convenient food storage, preserving and canning. Each jar holds 290 milliliters and features the characteristic Quadro shape combined with the WECK sealing system, making it suitable for jams, pickles, sauces and dry goods. The jars are made from durable, heat-resistant glass that can be reused and cleaned easily, supporting home preservation and kitchen organization.

Advantages

The Quadro shape provides stable stacking and efficient use of cupboard space while the wide mouth simplifies filling and cleaning. The WECK sealing system—glass lid, rubber gasket and stainless steel clips—creates a reliable seal for canning and vacuum storage without relying on single-use materials. Heat-resistant glass tolerates typical home canning temperatures and does not absorb odors or flavors, allowing repeated use for different foods.

Suitable for

• Home canning and preserving jams, jellies and fruit spreads
• Storing pickles, relishes and marinated vegetables
• Packaging sauces, dressings and single-portion meals
• Organizing dry goods such as spices, nuts and grains
• Gifting homemade preserves or meal kits

How to use

Before first use, wash jars, lids and gaskets in warm soapy water and rinse thoroughly. To preserve foods, fill jars leaving appropriate headspace for the recipe, position the rubber gasket on the lid, place the lid on the jar and secure with clips. Follow standard home-canning time and temperature guidelines for your recipe. After cooling, verify that the seal is complete; remove clips for storage. For non-canning storage simply place gasket and lid on the jar and secure as needed. Clean jars after use by hand or in a dishwasher, removing rubber gaskets for separate cleaning and inspection.

Usage recommendations

Use jars with intact rubber gaskets and clips for any heat processing. Replace gaskets if they show signs of wear or deformation. Allow hot jars to cool gradually and avoid severe thermal shock such as placing a hot jar on a cold surface. Store dry goods in a cool, dry place and ensure lids are seated to maintain freshness.
