Sanitaryware

Ceramic Materials for Casting Performance, Forming Control and Fired Quality

Sanitaryware manufacturing depends on ceramic raw materials that perform consistently through slip preparation, casting, draining, drying, glazing and firing. Products such as toilets, sinks and basins often combine large dimensions, complex shapes and strict surface-quality requirements, making material selection critical to both production efficiency and fired quality.

Covia supplies ceramic minerals and prepared materials for sanitaryware body formulations, including kaolin slurry, casting kaolin, refined ball clay, ceramic silica and sodium feldspar. These materials support pressure casting, plaster casting, automated production and fast-fire sanitaryware manufacturing.

Sanitary Manufacturing Challenges

Sanitaryware production places heavy demands on casting body performance. Manufacturers must balance casting speed, slip stability, drainage, formed strength, fired color and dimensional control while maintaining efficient production schedules.

Common technical needs include:

Fast, consistent casting to support throughput and wall formation.

Stable rheology for controlled fluidity, viscosity, thixotropy and deflocculant response.

Reliable drainage and release to help reduce defects in large or intricate cast pieces.

Formed strength for demolding, trimming, handling and drying.

Clean fired color and surface quality for white and light-colored sanitaryware.

Compatibility with automation and fast firing for modern sanitaryware production environments.
