Gleason Ball Clay

Fine grainding plastic ball clay

Oxide Weight343.92
Formula Weight389.14
If this formula is not unified correctly please contact us.

The manufacturer describes it as a fine-grained engineered blend offering excellent bonding and forming characteristics. Ideally suited for extrusion, dry and wet pressing applications. This material is an alternative to, for example, OM#4, it has a lower coal content and fires a little lighter in color.

Gleason ball clay fired test bars from cone 7-11 oxidation and cone 10 reduction

The oxidation bars (lower) are typical of most ball clays. They burn off-white and darken slightly in color as they approach maturity (above cone 10). Ball clays are fairly refractory, often as much more more than common fireclays. Ball clays almost always have some soluble salts and these reveal themselves in reduction firing (top bar).
