Glass Jar WECK Quadro 290 ml set of 6 — straight-sided preserving jars with lid and rubber gasket

WECK Quadro 290 ml glass jars in a set of 6 are straight-sided preserving jars designed for home canning, food storage and presentation. Each jar has a 290 ml capacity and comes with a glass lid and a rubber gasket to provide an airtight seal when used correctly. The clear glass construction makes contents visible for easy identification, while the straight sides simplify filling and stacking. These jars are reusable and suitable for a range of kitchen tasks, from preserving jams and pickles to storing dry goods and creating gift jars.

Straight-sided design facilitates even filling and neat presentation. Jars are dishwasher-safe for convenient cleaning and are reusable, reducing single-use packaging. Transparent glass helps monitor contents and levels without opening.

How to use

Wash jars, lids and gaskets before first use. Fill jars with prepared food while hot or cold according to your preserving method. Place the glass lid on the jar with a clean rubber gasket positioned between lid and jar rim to create a seal. For water-bath or sterilizing methods, follow standard home-canning procedures and heat treatment recommendations to ensure safe preservation. After cooling, check that the gasket has formed an airtight seal. For everyday storage, simply close the lid with the gasket in place to keep contents fresh.

Usage recommendations

Use compatible replacement rubber gaskets if the original gaskets show signs of wear. Avoid sudden temperature shocks to the glass (do not transfer jars directly from freezer to boiling water). When using heat-based canning methods, follow verified recipes and processing times appropriate for the food type to ensure safety. Clean lids and glass in dishwasher; hand-wash gaskets to extend their lifespan.
