17/18mm porcelain buttons muave granit These are about 16x16mm andPorcelain buttons Muave. These are about 17mm and sold in different sets. The buttons were fired two times. First firing is the so called bisque firing where temperature goes as high as 1000C degrees. After that our buttons are ready to be glazed. We put 2 layers of glaze manually and when they've dried, buttons are fired for the second time at about 1230C degrees. The backside of the buttons stays unglazed. Its like a stone to the touch.
