During a recent journey to Antigua, Guatemala, I happened upon Mayu.

The MAYU HAND PAINTED MINI BOWL WITH FEATHERS is finely crafted in San Antonio Palopó, Guatemala, and fired at elevated temperatures in traditional ceramic ovens. The unique feather designs were inspired by native birds and traditional Guatemalan art such as the Chilmolera. Also available in solids.

It measures  approx. 2.3" x 5.5", is rated for high temperatures, and is suitable for microwaves and conventional ovens.
