Ever wondered how freezer mugs work? What is it in these mugs that make them function the way they do, like keeping your beverage cool and refreshing long after removing them from the refrigerator? Basically, these mugs are containers with a double-side wall, filled with a certain type of gel-a mixture of propylene glycol and water-at the core, which serves as an antifreeze. The antifreeze works by keeping the mugs’ freezing point lower than what it usually is, so in effect, the liquid contained in it is kept cold for a longer time. While it is similar in many aspects to the freeze preventive used in automobiles (ethylene glycol), propylene glycol is considerably less toxic, so the freezer mugs are still kept safe even in cases of accidental leakage.
Freezer mugs come in a variety of styles. You can find them in the form of a beer mug, a wine glass, or even a tumbler. You can also find them plain clear or frosted, or even with colored gels inside, depending on your preference. These mugs can also be made from different materials, such as plastic, glass or acrylic. But whatever the material your mugs are made from, it is important that they are well taken care of. Habitual use in environments of very different temperatures can shock the mugs and cause them to crack, so it is important to know how to properly store them.
To care for your mug, wash it in lukewarm water by hand and place it in the refrigerator for an hour to cool it down. Remember not to leave it soaking in the water or to use a dishwasher to clean it. Afterwards, move the mug to the freezer and put it in an upside down position, out of the direct path of the air inlet. By the time you need to use the freezer mug, take it from the freezer and wrap a dry towel around it. You are now ready to use your freezer mug again.
