This is a handmade mug that can be used to hold your daily brew. It is made from Stoneware clay on the pottery wheel. It was dipped in a wood ash glaze called a Nuka glaze, and then brushed with a copper stain to give an earthen, green color. The copper glaze dripped down thepot during the firing, creating green colors in the cream colored base glaze. The mug is 100% functional, dishwasher safe and microwaveable. It measures about 4" tall, width 5" including handle. This mug is perfect for that every day small cup of joe to get you going in the morning.
