This is a large round embossed porcelain button. edging. They are durable buttons and would make a wonderful accent for a purse, hat, pillow, clothing, accessories and craft project. They measure 40mm or 1-1/2 inches. I have 10 blue buttons and more in different colours in stock. My porcelain buttons are created from hand rolled porcelain clay. I first hand roll and emboss, then drill each button which I then fire to 1000 oC. Once fired and cooled I hand paint onto the back of the button my wax resist. Then I brush my under glaze colour into the embossing and then wipe the surface with a sponge leaving the under glaze in the recesses. The button is put to one side for 24 hours to dry before dipping into my transparent glaze then refired to 1260 oC. Please contact me with any questions about our product. I make our buttons in a variety of shapes,sizes, and colors and we love special orders.
