When making tea with loose leaves, a tea mug with infuser can make it easier and prevent mess. This one with a lid allows you to brew tea in the cup and then discard the leaves. The cup and infuser are also chip-resistant, so it is built for longtime use. Each pattern will vary. Polish Pottery obtains their hand-painted stoneware directly from Boleslawiec, Poland. The colors are inspired by the blue, green, and earth tones of the peacock. All are made of indigenous white clay, and are fired at excess of 1350 degrees Celsius so that they retain both heat and cold for long periods of time. A great gift to include in a tea gift basket!
