Cheap, strong, standard. Since the Mason jar was first patented in 1858 by Philadelphia tinsmith John Landis Mason, people have been finding uses for them other than the traditional food preservation that they were designed for.
The Mason jar was the killer app of its generation, providing a common platform for inventors and innovators of all kinds to create useful things. While never out of style, the common glass canning jar has been making a serious resurgence in the past few years, becoming a standard fixture in people’s glassware collections and even as serving vessels in restaurants. You can store, bake, preserve and drink out of them. They are dishwasher, microwave and oven safe. They are the perfect container to pack your breakfast/lunch/snack or dinner in!
At Masontops we love the glass canning jar as much as everyone else and want to make them even more useful by providing unique and helpful tools to convert the common glass jar into something even more special!
