I mainly work with varieties of stoneware that I have chosen for their plasticity and their aesthetic appearance after firing. I have also recently ventured into porcelain, the renderings of which I like. But it's a path I'm only beginning to explore. My pieces are enamelled at high temperatures and always leave a good part to the clay that I want visible whatever the pieces.
They are utilitarian, I do not use heavy metals in the enamels. There is no issue putting them in the dishwasher, in the oven or in the microwave. On the other hand, they must not be put in direct contact with a flame.
