What is the difference between a mason jar and a perfect mason jar?

Where did Ball jars originate?

It is best known for its early production of glass jars, lids, and related products used for home canning. Since its founding in Buffalo, New York, in 1880, when it was known as the Wooden Jacket Can Company, the Ball company has expanded and diversified into other business ventures, including aerospace technology.
