As few as 12 grains of chromite in 500 grams of silica sand can render the sand unfit for glass production. If a silica product has 1 grain of refractory mineral per 500 grams, a typical glass plant using 350 tpd of sand would have in excess of 700,000 defects per day; far too many to make the sand a desirable component.
