Antique CJFCo Mason's Improved Jar Clyde NY Amethyst Purple Quart Vintage RARE

I bought this years ago at antique shop. Because I loved the purple color and the fact that the old glass lid and screw top were in such good shape.

There are some tiny bites along the rim of the jar and lid. J 133 is on the bottom. And stamped Clyde NY on back. The shop owner told me that the jar was originally clear but whatever chemical they manufactured these with - changed color over time.

It is a beautiful purple color.
