Did you know there are a variety of different types of ceramics and materials to make coffee mugs? There are about five basic kinds- dolomite, stoneware, bone china, earthenware and porcelain. Dolomite is the cheapest, very lightweight and easy to break. On the plus side, dolomite is easy to sculpt and decorate for souvenir mugs. Bone china is very durable, beautiful and makes great tableware. Porcelain, which is ideal for elegant and expensive dinnerware, is usually made with kaolin clay and fired at a very high temperature of 2600 degrees. It is also very beautiful but more fragile. Earthenware is most often used for hand crafted pottery. It is easy to work with by hand and is truly and earthy looking. We primarily use stoneware, which is somewhat of a combination of all of the above. Stoneware is durable, can be sculpted and decorated, and can be fired with glazing. It is a high quality material, retains heat, and have a great feel to it and helps make coffee taste great! Stoneware is also dishwasher safe.
