Can these jars be used for traditional water-bath canning and fermentation, and do the lids provide an airtight seal?

Yes, the 2-piece lid design is specifically for water-bath canning. The vacuum seal forms as the jar cools. It’s also excellent for fermentation and pickling.

Are the metal lids rust-resistant, and what is the best way to clean them for long-term use?

Lids feature a rust-resistant finish. To maintain it, please hand wash and dry immediately with a cloth. Avoid soaking or air-drying in damp areas.

Do these jars follow standard mouth specifications for lid replacements and accessories?

Yes, these feature the Standard Wide Mouth (86mm). They are compatible with all universal 86mm accessories, including fermentation airlocks and replacement lids. The wider opening allows for easier cleaning and filling.

Is the glass durable for dishwasher and freezer use, and can it be heated in the microwave?

Made of thick soda-lime glass, these are dishwasher (glass only) and freezer safe (leave headspace). To prevent thermal shock, we do not recommend microwave or oven use.

What types of food are recommended for this specific jar size, and is it suitable for long-term pickling?

Perfect for pickling onions or beets; storing large-batch jams, overnight oats, or salad dressings. The wide mouth enables easy filling, while the split lid ensures reliable airtight sealing—ideal for home preserving and healthy meal prep.

Perfect for preserves and drinks

Just received our second set because we needed more. They're brilliant. We use them for things like nuts, jams, spreads, sauces, chutneys, hot chocolate powder, but they also make really nice drinking glasses. The stickers and twine are cute additions too. We've used them to label baked goods we give to friends and to package spare chutney as a gift - very functional and aesthetic :)

Handy table size

Jars don't look out of place on the table being larger than a shop bought jam jar.

Lovely Mason Jars but .......

Lovely Mason jars received today. They appear to be a very well made product. That was until I used them yesterday and one of them cut my finger badly. First time I had used them and I have been "bottling" for years, but this is the only time I have ever had a jar crack when water canning. I am not new to this system of bottling, and take all the right precautions to ensure safe usage, but this really was disappointing. If the seller has a spare jar, I would appreciate one being sent to me. Thank you!

Storage jar

Received the item well packed and fast. After giving a good wash started to store all my dried spices. Look neat and easy to open and close the cap. It also comes with label but I had preorder a pre named sources labels so did not use the one comes together with the jar. Overall it's worth and I'll definitely order another set
