Wheel thrown and hand carved porcelain mug. Holds 14 fluid ounces. 
The glaze used on the exterior of the mug contains neodymium oxide, a rare earth element. This oxide is dichroic, which means that it changes appearance in different light sources. I have included an image to show a variation of how it might appear in a different light source. It can rain from muted gray/blue to lavender two a bright and bubbly purple.
