WECK Tulip Canning Jars 0.36 L (12.5 oz) — Set of 6 with Glass Lids & Complete Seal

These WECK 746 tulip jars are 0.36-liter (12.5 oz) glass canning jars sold as a complete set of six with lids, rubber gaskets, and clamps for reliable reusable food storage and processing.

Designed and manufactured in Germany, the WECK 746 tulip jar blends classic European canning design with thick, durable glass suitable for boiling, sterilizing, freezing, and baking. The set includes six glass lids, six replaceable rubber gaskets, and twelve stainless clamps so you get everything needed for water-bath or pressure canning as well as everyday pantry organization. These jars are free of BPA, lead, PVC, and phthalates, and their glass lids avoid rusting issues found with metal tops.

How do these jars perform for home canning?

The 0.36-liter tulip jars are sized for single servings, condiments, small jams, and preserved herbs. Their thick glass tolerates repeated high-heat processing in water baths and pressure canners, while the wide mouth simplifies filling and cleaning.

• Thick borosilicate-style glass resists thermal shock during boiling and sterilizing
• Complete sealing system: glass lid + rubber gasket + metal clamps for secure processing
• Wide mouth reduces spills and speeds jar-filling
• Set includes extras so you can process multiple jars at once

Can I freeze or bake with these WECK tulip jars?

Yes — the jars are suitable for freezing and oven use when handled properly. Leave headspace when freezing and avoid direct contact with open flames or sudden temperature shifts to protect the glass.

• Freeze-friendly glass lets you store prepared meals or sauces
• Oven-safe for gentle baking or reheating (not for broilers or stovetop)
• Allow jars to come to room temperature before dramatic temperature changes

What makes WECK 746 jars a reusable, sustainable choice?

These jars are built for repeated use: durable glass, replaceable rubber rings, and non-rusting glass lids extend the product life beyond single-use containers. The components are recyclable and free from common plasticizers, reducing waste and chemical exposure.

• Replaceable gaskets keep jars functional for years
• Glass lids avoid corrosion and last longer than metal tops
• Materials are free of BPA, lead, PVC, and phthalates
• Glass is fully recyclable and easy to sanitize

How do I tell if a jar is properly sealed?

WECK’s seal system gives a clear visual indicator: the gasket tab points downward when the vacuum seal is intact. After processing, check that clamps are secure and the tab faces down to confirm a successful seal.

• Gasket tab facing downward = sealed jar indicator
• Clamps keep lid and gasket aligned during cooling
• If seal fails, reprocess promptly or refrigerate for short-term use

Who is this set for? Home canners looking for a reliable small-size jar, cooks preserving single portions, bakers reheating or storing individual servings, and anyone organizing pantry staples will appreciate the WECK 746 tulip jar set. It’s suited to people who want attractive, long-lasting glass containers for canning, freezing, gifting preserves, or displaying pantry items on open shelving. The included lids, gaskets, and clamps make this set a convenient all-in-one starter for newcomers and a dependable addition for experienced preservers.
