This cup was made from Stoneware clay on the pottery wheel. It was dipped in a wood ash glaze called a Nuka glaze, which comes from Japanese historical pottery and causes the pot to have a cream color. It was then brushed with Cobalt blue stain to give an earthen feel. The cobalt blue dripped down the glazed pot during the firing, creating blue color hues in the cream colored base glaze. The cup is 100% functional, dishwasher safe and microwaveable. It measures about 6" tall, width 3.5" including handle.
