Handmade wheel-thrown mug, hand-painted with glaze and adorned with real gold lightening strikes and starscape. Because this mug is made with real gold, it is not microwave safe and should be hand-washed when possible. Repeated time in the dishwasher will cause the gold to lose its luster. Each moonscape mug is completely unique, and there are variations from mug to mug, as is the nature of handmade items.
