Porcelain 1.5 x 1.5 cm Please note that each piece is hand-crafted and unique, so your actual jewel may slightly differ from the picture. Care: the porcelain pop-corn is unglazed, and can be cleaned easily with a toothbrush and soapy water. Monochromatiques is a collection of porcelain jewels and accessories that are completely handmade at a studio in the countryside near Paris. Each ceramic piece is unique: it is hand-shaped, then fired at 980°C, glazed with a brush or by soaking, and finally re-fired at 1,240°C, which makes it vitrified and robust. When using metal, different techniques such as the lost wax casting has been applied.
