History & Identification
Your jar is an authentic early 20th-century Ball Mason jar, likely produced between 1920-1923. Ball Brothers started making glass jars in 1880, and their Ball script logo evolved over time, which helps date jars.
The "Ball Blue" color was made from sand sourced from Indiana, which had a natural bluish tint.
The molded bubbles and dimples indicate early manufacturing techniques before fully refined glass-making methods.
The number on the bottom (6 or 9) is a mold number, not a year or specific date code.
