The mason jar was invented and patented by John Landis Mason, a Philadelphia tinsmith in 1858. Mason jars are made of soda-lime glass. While some are worth just a few dollars, some have sold for as high as $30,000. Coloured jars were considered better for canning, as they block some light from reaching the food, which helps retain flavor and nutritional value longer.
I have a large one filled with marbles, collected from my childhood and that of my husband's. I love how they catch the light when the sun comes through!
