There are many beautiful cups in American grocery stores, called Mei Sen cans, named after American inventor John Mei Sen, which translates into Mason cups, or Mason bottles and Mei Sen cans. Originally used to preserve or preserve food, it consists of a transparent large glass and a perforated metal cover, which means it is similar to a sealed can.

Because Mason Cup is made of ordinary glass like windows, the temperature difference of boiling water will make it burst, and potassium glass is afraid of drastic temperature difference change, so Mason Cup can't hold hot water, only cold drinks are recommended.

Other uses

Mason bottle was invented by John L in 1858. The original intention of this jar was to prolong the life of food, just like pickles and sauced meat are used to preserve food at home. If these pickled foods want to be preserved for a long time, they need excellent airtight containers, so Mason bottles were invented.

Mason bottle has many new uses because of its fresh appearance, rich size and strong plasticity. It can be used to pickle pickles, make coffee cups and cups, bring salads to work, make unique layered brownies, and even make light bulbs, vases, potted plants and toilet storage bags.
