Hands on advice for successful sand reclamation | Castings SA

At elevated temperatures, and in an oxygen containing atmosphere, Fe oxides and chromite sand increase in weight. Because of this increase in weight during the LOI test, standard LOI testing cannot be run on chromite sand or chromite-silica mixtures. This change partially makes up for some of the weight loss because of the binder being burned off.
