This is a large round slip trailed and glazed porcelain button. 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. My porcelain buttons are created from hand rolled porcelain clay. I first hand roll and then drill each button. whilst still wet and in its unfired state I hand brush a yellow square of slip into the centre of the button and then slip trail lines in black across the button. The button is then fire to 1000 oC. Once fired and cooled I hand paint onto the back of the button my wax resist, 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 colours and we love special orders.
