The Manufacture collection from Villeroy & Boch combines premium porcelain with high-quality craftsmanship. Inspired by natural materials with strong color accents, Manufacture Rock and Rock Blanc offer a look that resembles natural slate. A light glaze that’s added over the porcelain gives each piece a rustic, from-nature look. The black color of Manufacture Rock resembles natural slate, while Manufacture Rock Blanc offers texture in a crisp white.
