Passion for Innovation

As a leading Portuguese stoneware manufacturer, we proudly oversee a portfolio of four exceptional factories,
producing more than 1.000.000 pieces per month.
Each piece of stoneware begins with a spark of inspiration and a meticulous design process that prioritizes innovation and sustainability.
Our talented designers consider every aspect, from form and ergonomics to aesthetics and the product’s life cycle, ensuring minimal environmental impact. We source raw materials locally from Portugal’s finest natural resources and incorporate recycled elements to enhance our commitment to sustainability.
Our stoneware is crafted from natural clay and mineral-based materials, making it eco-friendly and biodegradable, with a manufacturing process that uses significantly less energy. Additionally, all of our excess clay is reused.
Mold Manufacturing

Where Design Takes Shape

Each piece begins its journey in a carefully crafted mold that establishes its form and character. Because our molds are designed and produced in-house, we maintain precise control over every detail. This process ensures that each stoneware piece meets our uncompromising standards for quality, innovation, and aesthetic excellence.
Our commitment extends through every production stage – from casting and molding to decorating and glazing – where precision, craftsmanship, and rigorous quality control are essential. Even the firing phase plays a critical role: our stoneware is single-fired, a process that minimizes energy consumption and reinforces our dedication to sustainable manufacturing practices.
