The Weck Tulip Jar is a 19.6 fl oz German-made glass canning jar with a wide 3 7/8-inch opening and a tulip-shaped body. It seals with a glass lid, a removable orange rubber ring and two metal spring clamps, and Weck rates it for both water-bath and pressure canning. The wide mouth makes it easy to fill, scoop from and clean, and the clamps come off so it doubles as a sourdough starter or pantry jar. Against Mason jars it trades screw bands for clamps and rubber rings, which need replacing over time, but the all-glass look and stackable shape appeal to people who leave jars on display.

Owners of Weck jars generally praise the thick glass, the wide mouth and the airtight seal, and many use them for jam, pickles and sourdough starter. Complaints center on rubber rings that stretch or fail and clamps that rust.
