Good question! And there are plenty of other good alternatives, so you can take your pick - glass, wood, or ceramic! When mixing beauty recipes, the most important part after procuring the purest of ingredients, is to keep the pH of those ingredients from being altered, which can be the case with metal accessories. And throwing pH off, affects efficacy of your recipe and potentially affects how your skin reacts to it. 

Clay bowl is neutral to your ingredients and feels so wonderful in your hands - it is like holding a piece of history and going back in time...

Our clay bowl is not made on a pottery wheel from fine porcelain grade clay. It is not subjected to high temperature kilns and it is not glazed. An entirely different ancient process is used and each bowl is made in one village in Tunisia, protected by UNESCO as one of the oldest pottery crafts in the world. 

The clay from the foothills of Atlas Mountains is hand carried by the artisans back to the village and mixed with sand for a porous, raku-style texture. Each bowl is shaped by hand and fired in low temperature fire just a few pieces at a time. It is not glazed, but rather painted with black clay and coated with tree resin to be water resistant. Each chip and crack is meant to be there. Each bowl is unique and perfectly imperfect.
