Ball clay for ceramics
Imerys has ball-clay assets the world over
Ball clay is an extremely rare mineral, only found at a handful of locations around the world. Imerys owns and mines high-quality ball clay deposits in the UK, France, Thailand and the United States.
Additionally, our processing platforms in India, Algeria and Egypt ensure local ball clay production meets the specific technical challenges of each region.
Ball clays are highly valued in the ceramics industry for the manufacturing of sanitaryware, tableware, tiles and slabs, technical ceramics and electrical porcelains, where they are essential for controlling the plasticity and casting properties of the ceramic body, for blend cohesion and for improving workability.
Our ball-clays offer a unique balance of properties
Our ball clays for ceramics are characterized by their unique balance of properties, such as:
- High plasticity
- High unfired mechanical strength
- Highly controlled rheological properties
- Controlled organic content
- Controlled residue
- Excellent workability
We guarantee the excellence of every batch with consistent, first-rate raw materials.
Our ball clay offer for sanitaryware
Used in sanitaryware, ball clay is crucial for achieving the precise shaping of the final sanitaryware piece.
Our comprehensive range of ball clays for sanitaryware offers varying degrees of plasticity, fluidity, and strength — allowing you to select the ideal grade to match your specific formulation requirements.
Due to their balanced properties and consistent quality, all of our ball clay grades are suitable for high pressure casting (HPC). Our optimized grades for HPC — such as Hycast Rapide and Proxicast — have demonstrated excellent performance in HPC applications.
Our ball clay grades for sanitaryware are produced in the UK, Egypt, Algeria, India, Thailand and the United States.
Recommended ball clay grades for sanitaryware
Hycast VC
Hycast VC is a balanced ball clay with good all round properties (fluidity, strength and plasticity). It is a versatile clay, presenting:
- Medium dry mechanical strength
- Medium casting rate
- Stable rheology due to the presence of organic species
Hycast Plastic
Hycast Plastic is a ball clay demonstrating high plasticity, low residue and good fluidity.
It is ideal for achieving:
Fewer cracks: good rheological properties promote cleaner draining slip, eliminating slip hang up — a major cause of cracking.
Less damage: high MoR means less damage during handling.
Plasticity: crucial to finishing (cutting and punching) and forming of the piece and to resisting stress during drying.
Hycast Rapide
Hycast Rapide is a high casting ball clay combining increased casting rate with good mechanical strength. It is specifically designed to meet the requirements of High-Pressure Casting (HPC) units.
Hycast FFC
Hycast FFC is a specially blended, shredded ball clay valued in Fine Fireclay (FFC) applications due to two key properties:
- Superior fluidity - enabling the creation of high-density slips.
- Higher silica content - promoting high thermal expansion in the fired piece, ensuring a strong body-glaze interface.
- Proxiplast
Featuring a fine particle size distribution, Proxiplast delivers high strength, fluidity and low residue, making it ideal for producing sanitaryware pieces with good plasticity.
- Proxicast
With a slightly coarser particle size distribution, Proxicast provides firmer green strength for easier handling and shaping.
- Modiscast S2
Modiscast S2 is a fully refined, fluid, high strength ball clay with medium to low carbon content. The fine particle size compliments bodies using coarse fast casting kaolin to improve green strength and optimize drying properties.
- Thaicast S1
Thaicast S1 is a semi-refined clay providing a good balance between plasticity, fluidity and particle size distribution. It is suitable for all casting processes.
- Certicast R8i
Certicast R8i is a shredded ball clay blend demonstrating medium strength, fluidity and optimized medium sized particle size distribution. Specifically designed to complement local kaolin properties, it provides enhanced firmness and drying performance of sanitaryware bodies.

Our ball clay portfolio for tableware
In tableware production, ball clay — when used alongside kaolin, feldspar, and quartz — delivers both high plasticity and a bright white-fired finish.
Our tableware-grade ball clays are engineered to provide an exceptional balance of whiteness and plasticity, ensuring superior workability and consistent results. Additionally, naturally occurring organic matter in our clays stabilizes rheology, reducing the need for deflocculants and minimizing related defects.
We offer a wide range of ball clays from the UK, US and France which are especially well-suited to meet the exacting standards of tableware manufacturers.
