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.

Poor manufacturing quality, multiple long cracks and bubbles in glass, asymmetrical off-centred bottom

Excellent quality. Easy to clean, seal well and attractive. This size (WECK 743) is excellent for sourdough starter as recommended in, “The Perfect Loaf” cookbook (which we also recommend).
