Rio Clays minerals are batch-tested for glaze compatibility, ensuring procurement and engineering teams achieve zero-defect production goals.
Engineered Kaolin for Engobe Optimization
Performance Case Study
By integrating Rio’s high-purity kaolin into the engobe formulation, a leading tile manufacturer achieved a lesser reduction in surface defects and significantly improved whiteness. This technical transition stabilized fluid viscosity and enhanced coverage, maximizing production yields in rapid-cycle industrial kilns.
Viscosity Control
Optimized rheological engineering ensures stable glaze performance and uniform coating weight throughout high-speed production.
Whiteness & Opacity
High primary whiteness values maximize brightness while superior layer opacity allows for reduced total pigment consumption.
Suspension Stability
Excellent anti-settling properties maintain consistent mineral distribution, preventing homogenity loss in delivery systems.
Defect Reduction
Stabilized firing behavior and thermal expansion control significantly reduce interface stress and surface pinholing.

A high-volume thin slab producer reported a 22% reduction in breakage and significantly lower warpage after integrating our engineered blends. The optimized vitrification profile stabilized dimensional yield, maximizing A-grade output in ultra-fast industrial firing lines.
Kaolin in Ceramic Slabs
Use-Case: Production Consistency
A large-format producer transition to Rio Clays kaolin for their 1200x2400mm slabs. By integrating our engineered mineral from initial body formulation through to the engobe layer, the producer achieved uniform vitrification and reduced thermal stress mismatch. This optimization resulted in significantly fewer edge defects and a 15% improvement in A-grade yield for their large-format production lines.
Rio Clays kaolin is engineered to meet the stringent demands of ceramic slab bodies and glazes. In body formulations, it provides the critical green strength and thermal stability needed to maintain extreme flatness in large formats. In glazes and engobes, its high purity and controlled particle size maximize whiteness and firing stability, ensuring a defect-free surface finish across high-speed industrial kilns.
