In general, <br />a grit content of less than 10 per cent and a colloidal yield <br />of more than 30 per cent is considered favorable. However, <br />additional evaluation tests are needed to fully evaluate a <br />clay sample. These additional evaluation tests are being <br />developed. <br /> <br />1017 <br />
