Do ceramic mugs retain heat?
Ceramic Mugs Retain Heat Well The little air pockets that develop in the pores of ceramic act as heat insulation, slowing the process of conduction. Ceramic has a higher specific heat than glass, which means ceramic will lose heat through convection at a slightly slower pace with ceramic than with glass.
Why do some ceramic mugs get hot in the microwave?

Do ceramics have lead?
Lead is used in the glazes or decorations covering the surface of some ceramic dishes. Other sources of lead, such as lead in paint or soil, are much more likely to be a problem. In some cases, however, lead in tableware can be a serious health threat. Some dishes contain enough lead to cause severe lead poisoning.
How can you tell if ceramic is lead free?
Look for a warning label. If the pottery was manufactured for use only as a decorative item, it may have a warning stamped onto the clay bottom such as “Not for Food Use—May Poison Food.” Do not use items with this type of warning for cooking, serving, or storing food or drinks.

Porcelain mugs are made from kaolin clay and fired at temperatures as high as 2,600 degrees Fahrenheit. This makes an exceptionally white ceramic and can make very thin-walled vessels. Because of the thick sides, they retain heat longer than other mugs.
What material keeps things hot the longest?
Materials that are good insulators keep liquids hot for a longer time. Examples of good insulators are silicon, various polymers that form gels and foams, and glass.
Do ceramic mugs get hot in microwave?
When it comes to “microwave-safe” mugs, it’s not just toxic substances we were concerned about. We found both aged and new samples of several mugs got hotter than allowed by the standard. However aged samples were more likely to get hot and to reach even higher temperatures than new samples.
