What is the height and width of the jars?

The whole dimensions of Weck Canning Jars 743 are the following: - Height: 5 3/4″ - Opening: 3 7/8″ - Volume: 28.7 fl. oz.

How tall and wide are these Weck 743 Mold Jars for sourdough starter?

Jar with lid is approximately 6" tall and again with lid, about 4.25" wide. I have been using this card for sourdough and like it very much for that application.

How do you get the lid off? I took the clips off and it's stuck on and I'm afraid I'll break the jar.

These jars are very solid so should not break easily. You can gently pry off the lid with a thin knife or soak it in hot water to release the rubber seal.

How much do these jars actually hold? I see 4 liters, .75 liters, 28.7 ounces, and 25.3 ounces. Which is it?

Jar model 732 holds 3/4 liter=25.36 oz.

Breaks very easily

I bought these jars in February. One of them is broken already while I was discarding my sourdough starter with a spatula. Not happy at all as I thought they would last longer than that given the price of them.

Perfect for Sourdough Starter and Spice Storage!

I've been using my jars to hold my sourdough starter and as spice storage. I love that I can sterilise it easily and it's easy enough to clip it shut when I need a good seal. Perfect for what I was looking for!
