This is a large round porcelain button with a beautiful hand painted blue and yellow cornflower design. The over glaze flower sits on a surface of high fired transparent glaze to show through the porcelains natural beauty. They are durable buttons and would make a wonderful accent for a purse, hat, pillow, clothing, accessories and craft project. They measure 35mm. My porcelain buttons are created from hand rolled porcelain clay. I first hand roll and drill each button which I then fire to 1000 oC, Then I dip into the transparent glaze which once dry I then fired to 1280 oC. Once cool I brush hand paint my flower on then complete the button with a third firing at 780 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.
