The Manufacture collection from Villeroy & Boch combines premium porcelain with high-quality craftsmanship inspired by natural materials with strong colour accents. Manufacture Rock and Rock Blanc offer a look that resembles natural slate, thanks to the light glaze that’s added over the porcelain to give the pieces that rustic, from-nature look. The color of Manufacture Rock resembles natural slate, while Rock Blanc offers pieces in a crisp white.
