This is a black on white, organic paint, round bottom mug. I ship these round bottomed pots with willow “rings” as pot rests, and although this mug does sit flat, it could use a little extra support sitting on a table or other flat hard surface.
Interestingly the majority of the ancient pots from the southwest are round bottomed because they were either set on the soft ground or used on the coals; They did not need to be flat on the bottom!
I have always gravitated to the round soft shapes, especially because they are more unusual in the modern “mug world” and I love that contrast with the sharp geometrical designs.

All my pottery is hand made from wild harvested clay, painted with either organic or mineral paints using a yucca brush. I fire the pots in a trench-pit fire. All materials used are collected and refined by me.
