This is done by adding MgO in the finest sizes only, and possibly by screening out some of the finest chromite. Hence a structure is produced made up of relatively large grains of chromite in a matrix largely of forsterite. Grading becomes very important and an excess of free MgO in the matrix can only increase refractoriness
