Dating Kerr Mason Jars: A Step-by-Step Guide

• Look at the Logo: Early Kerr jars are marked with the "KERR" logo in all capital letters, while later versions might have different font stylings. Changes in the logo over time can give clues to the jar's age.
• Examine the Bottom: The bottom of the jar can tell you a lot about its age. Numbers, letters, and other markings can indicate the mold used for the jar and, indirectly, its manufacturing period.
• Consider the Glass Color: Clear glass Kerr jars are common, but the jars also came in a variety of colors, including green, blue, and amber. These colored jars, especially rare hues, can often date to specific time periods.

• Consulting Vintage Catalogs: Vintage catalogs and advertisements can offer valuable information on the jar designs and features specific to certain years or decades, aiding in the dating process.
