Adelina, with yellow flower and green leaf pattern, is a stoneware breakfast set consisting of 26 pieces for 6 people. Stoneware is a soil-based material used in making plates and bowls by firing at 1100, 1300 degrees. It is much stronger than ceramic and does not absorb water compared to ceramic. Since it is cooked at higher temperatures, it can be used safely in the microwave, oven and dishwasher for many years.
