Vitreous China (VC) & Fine Fire Clay (FFC) Ceramic Sanitaryware

Sanitaryware is the generic term used to describe items which traditionally were made from pottery. i.e. WC’s, Washbasins and Bidets installed within a bathroom or washroom. Vitreous China (VC) is a common material used for bathroom sanitaryware, such as console sinks and toilets. Vitreous China sanitaryware products are primarily made of clay, kaolin, feldspar and quartz but they may also include small quantities of other raw materials. Its high gloss, stain resistant surface is ideal for use in both bath-rooms and kitchens. The casting slip is made of the above craw materials are prepared and cast into plaster moulds to form a green body. The green body then undergoes a natural drying process and were given a smooth finish. Glazing is applied before firing at 1200°C to obtain Vitreous China sanitaryware with almost no water absorption. In fine fireclay, (FFC) the pre-fired or calcined clay is the single most important component and can account for over 40% of the body. Other constituents include clay, kaolin and other minor raw materials. Their production starts with preparation of casting slip from the above constituents. The slip is cast into plaster moulds to form green body. The green body then undergoes a natural drying process and were given a smooth finish before tuner dryers. Glazing is applied before firing at 1220°C to obtain fire clay sanitaryware with water absorption less than 0.5% of the dry weight.
