There is a really great street lined with antique stores a couple towns over. I've had my eye on the south-jersey green mason jars for a while and today I finally purchased one. This one has a glass lid! According to a few online articles, this type of closure is called a bail closure. According to the docents at my work, the color of this jar is caused by the iron found naturally in the sand of south jersey. Glassblowers would have to add manganese to the furnace glass to change the color to clear. I LOVE the natural south jersey green!
In addition to visiting the antique shops, I tested and listed my shampoo spheres on my Etsy shop!
