You found a mason jar lid buried and was wondering how old it might be It is metal and white glass you have never seen a glass lid?

Answer 1

Mason jar lids with metal and white glass components were commonly produced in the early to mid-20th century, particularly from the 1920s to the 1970s. The white glass suggests it could be a type of glass called porcelain enamel, which was used to create a seal. To narrow down its age, you can research specific brands or styles associated with that design, as well as look for any markings or patents on the lid for more precise dating.
