Thermal behavior is another factor that distinguishes ball clay from kaolin clay. Both clays undergo significant changes during firing, but the resulting fired color can differ. Ball clay tends to exhibit a darker-fired color due to its impurities, while kaolin clay often produces a lighter-fired color due to its higher purity.
