What materials does FRANZ Collection use for its porcelain?

FRANZ Collection uses high-fired porcelain bodies designed to carry sculptured relief and rich colour glazes. Public descriptions refer to “porcelain” or “ceramic relief” rather than low-fire earthenware. The clay body must withstand multiple firings, since many pieces require separate firings for underglaze colour, overglaze enamels, and sometimes metallic accents such as gold. This firing schedule demands a dense, stable base. The surface often appears slightly translucent on thinner areas, with opaque sections on thicker sculptural parts. Glazes range from soft pastels to intense blues, greens, and reds, often layered to create depth around raised motifs like petals or wings. Some tableware lines use finer porcelain bodies closer to bone-china style for lighter weight and higher translucency, while large vases and figurines tend to use heavier bodies to support the modelling. Exact formulas are proprietary, so open sources give only general descriptions rather than detailed recipes.
