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.

The symbol of the Sun carried many meanings from the auction Sun in the sky, which gave warmth and light, to the Universal Deity, the Source of all life seen at times as both masculine and feminine. The Sun symbol was used to bring good fortune and enlightenment. It was depicted in a variety of ways usually containing concentric circles. The rays in the version represent the boundless generosity of the Sun Spirit and the beneficial effects they could produce.
