What is Ball Clay? – The Ball Clay Heritage Society
The name 'ball clay' derives from the former method of winning the clay by cutting it from the floor of an open pit in cubes. Because of the clay's high plasticity the cubes held together, but after being handled several times the corners became knocked in and the cubes turned into balls – so, to the potters, a plastic, white firing ...

Ball Clay Manufacturers And Suppliers In India
Ball clays would be ideal ceramic materials. However, in practical terms, they are employed to achieve the desired plasticity but are minimized to reduce the detrimental effect on fired whiteness and drying properties. Ball clay is a binding agent and helps to enhance the plasticity, workability, and strength of a pre-fired ceramic body.
Ball Clay v/s Kaolin Clay | ZSM
Ball clay, for example, aids in the slip-casting process. It improves the extrusion of a mix and, for example, the ram pressing of a mix. Ball Clay benefits by increasing the plasticity of the mix and making the mix more workable. Downsides of using the ball clay for more plasticity: There are two downsides to the ball clay. 1. One is …
clay plasticity/water content
Clay bodies have a narrow window of plasticity limits before they begin to fold. The problem is; potters judge plasticity in terms of water content which is not accurate. Plasticity is developed from a negative ionic charge in the water film: which is supplied by the CEC of any given ball clay.
