6 pcs. 23mm ceramic buttons orient 13 mm They are 15-16 mm bigCeramic buttons in dark blue brown. These are about 23mm and sold in a set of 6. 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. Can
