These cups are as eco-friendly as ceramic can be, thrown on the wheel from French clay, they are coated with a very simple yet beautiful glaze made out of the ashes from the stove of our studio. A nice way to re-use simple materials and turn them into a smooth surface with delicate colors (all from the iron naturally present in the clay). Another add of the nature surrounding our studio: the handle made with granite, volcanic ashes and wild clay.
