Ceramic Casting Kaolin
STARCAST®
The STARCAST® line of kaolin clays is designed for ceramic manufacturers preparing high-quality casting slips from shredded, semidried or air-floated raw materials. With a carefully balanced combination of particle size distribution, rheology and mineralogy, STARCAST is designed to improve casting rate and deflocculant response in traditional, automated and pressure casting operations.
For manufacturers working across a range of casting methods and ware sizes, STARCAST delivers strong slip performance throughout the casting curve. STARCAST is available in crushed, sliced and air-floated forms, giving ceramic engineers options for different raw material handling and body preparation needs. When used with Covia’s SANBLEND® refined ball clays, STARCAST expands the formulation toolkit for casting body development.
Product Highlight
STARCAST ceramic casting kaolin is designed for casting slip formulations that require stable viscosity, excellent suspension properties and consistent performance across the full density range. All STARCAST grades are low in residue and carbon, making them a strong choice for manufacturers seeking clean, reliable kaolin clay for casting applications.
In traditional, automated and pressure casting, STARCAST can improve casting rate, deflocculant response and plasticity while maintaining high-quality casting performance. These clays are suitable for smaller ornamental wares as well as large industrial pieces, with selected applications capable of achieving higher-than-normal slip densities.

Customer Support
Casting slip performance depends on more than a single material property. Particle size distribution, mineralogy, rheology, deflocculant demand, slip density and casting method all influence how a body behaves in production.
Covia’s ceramics team works with customers to evaluate those variables and select STARCAST grades suited to their application. For manufacturers developing or refining casting slips, Covia can provide technical guidance related to raw material form, casting rate, viscosity control, density targets and compatibility with other ceramic body components, including SANBLEND refined ball clays.
This application-focused support gives ceramic engineers a stronger foundation for improving slip performance, troubleshooting body behavior and building casting formulations that perform consistently in production.
Logistics
Covia brings deep logistics experience to ceramic casting customers, with supply capabilities designed to support consistent material access, delivery planning and production continuity. With varied raw material forms, packaging options and a robust supply network, Covia helps manufacturers plan around order timing and delivery needs. That combination of technical knowledge and logistics support helps ceramic operations maintain a reliable clay supply for traditional, automated and pressure casting applications.
