According to my research, you could still buy new blue Mason jars up until around 1930. Then, all of these jars started coming in clear glass only, save for a special production run from time to ...

For example, an Atlas strong shoulder Mason jar in a really rare cornflower blue and ambe-swirled glass sold for about $130. You'll find these in many sizes. Color is also an important factor.

The 5 Points Neighborhood Association is collecting empty glass jars to turn into inspirational art pieces. The jars will be distributed to seniors, veterans and people with disabilities.
