I bet you’re dying to find out…
It’s a vintage Mt. Washington mustard Jar! With the advent of refrigeration, and plastic that is cheap enough to mass-produce a bottle that can be used long enough to hold the mustard, the days where we need a glass jar like the one pictured has come and gone.
It has opened up a collectible field that can be very diverse. The containers could be made out of pottery, glass, or even metal. The shape is also as diverse as the material that the jar is made out of. It could be round, square (or a combination of both), squat, bulbous, or just about anything.
The mustard jar is for sale in my Etsy store, you can go there here. Just be sure to use coupon code STORESALE20 when you checkout. You can even use that coupon code on anything in my Esty store from now until July 22nd.
