M. Grey was born and raised on the Navajo Nation. She is born for the Mountain Coal and Edge Water People. She learned the art of etching pottery from her uncle and grandmother. She has then created and developed her own techniques. Grey’s coloring and etching style became very different and popular. Combining the process of horse hair and her artwork creates unique pottery work.

Horse hair from the mane is thrown onto the pottery while it is still very hot during the firing process. The hair burns when it touches the hot pottery, leaving a carbon stain cooked into the pottery. This makes each piece one-of-a-kind with its own unique, beautiful pattern.
