A ceramic mass - clay - is used to create the basin. Its type, smoothness and chamotte content depend on the size, shape and decoration of the wash basin. All these elements, as well as other details (e.g. the size of the hole, the colours of the wash basin, additional elements) are agreed with the client. The maximum diameter of the possible wash basin is approx. 50 cm. The shaped product is fired in a kiln at 900-950 degrees Celsius, depending on the requirements of the mass from which it is made. The result is "a biskwit" - a ceramic semi-finished product, which is the pre-baked mass after the first firing, not covered with a ceramic glaze. The next step in the creation process is glazing. Ready-to-use liquid or powdered glazes are used for this and mixed in other substances. Depending on the customer's preference, the basin can be smooth, single or multi-coloured, decorated with drawings made with underglaze paint (which can be precise) or by other methods, e.g. by imprinting interesting textures and patterns. The product is then subjected to another firing, the temperature of which depends on the fusibility of the glaze used and ranges from 1050 to 1200 degrees Cls. The type of clay and glaze used determines the hardness of the final product. The company makes free-standing washbasins as well as those that are placed in countertops. The process of making a washbasin takes approximately one week.
