During World War II, glassmakers shifted to selenium as supply for manganese dioxide was limited.
But if you’re one of the lucky ones to have found an old Ball mason jar, or if you are an avid collector of such items, then dating these things is very important.
Whether you’re in for the fad or you just simply adore these nicely crafted glass items, mason jars are truly worth owning.
They have a rich cultural history and have withstood the test of time.
And that’s why determining the date of mason jars are of utmost importance.
