Tableware

Like many ceramic applications consistency and purity of raw materials is critical in making fine tablewares. Our extensive mineral portfolio is designed to provide raw materials and prepared bodies to suit a wide range of applications including: artisticware, earthenware, stoneware, vitreous china, bone china, hotelware and porcelain.

The choice of body raw materials is driven by the properties desired during the key manufacturing stages and final aesthetic properties required in the ware:

Forming: fluidity for casting and workability (plasticity/green strength) for pressing/ extrusion
Firing: vitrification, strength, shrinkage, thermal expansion, colour stability
Aesthetics: low colouring oxides, translucency, ‘designed in’ colour

We work with our customers to understand their goals before developing an optimum combination of body raw materials including:

Plastic materials: our range of refined and blended plastic clays and kaolins work to ‘bind’ a mass together so that it can be modelled and then hold its shape when dried. 
Fillers: our specialist silicas control thermal expansion and shrinkage and also allow the body to breathe during firing.

Fluxes: Sibelco’s range of feldspathic minerals reduces the fusion temperature of the ceramic body and generally form glasses if heated to a sufficiently high enough temperature.
