A specific date that the mugs were invented is unknown, though we have some evidence that back in 4000-5000 BC, decorated clay mugs were found in Greece.

Nodaway, we are quite familiar with the mug usage, knowing that it is a relatively large container with a handle that holds quite an amount of liquid. The most commonly seen materials used to make the mugs in the market are ceramics, porcelain, steel, and glass with ceramics, porcelain, or bone china.

Cork Bottom Coffee Mug

The main purpose of the design of a mug aims at thermal insulation: thick walls that prevent the beverage from cooling or warming quickly, concave rims at the bottom that reduce the thermal contact with the surface on which a mug is placed. The ideal materials used to make the mugs are usually of low thermal conductivity, like porcelain, bone china, and glass. And also, a practical design of many mugs is the handles which keep the hand off the hot side of the mugs.

Dowan values both functionality and aesthetics in designing our BUILT-IN CORK MUG. The noticeable feature of it is that there’s a magnetically attached cork bottom. The cork bottom not only insulates the heat but also prevents scratching and staining. Being magnetically attached, it can be easily detached so the main ceramic body can be put into the dishwasher.

Also, a lid is designed for a splash-proof purpose. The lid features a sliding door on top, and the lid is sealed along the mug top edge with a rubber gasket to trap in the heat. Though it’s not sill-proof and airtight, it is still quite practical to keep your coffee warm for quite a while.

The large handle of the mug is also measured for an easy grasp. All materials that are used in making the mug are BPA/BPS-free.

Its design makes it an ideal product for personal daily use or an appreciated gift.
