NOTE: SILICON CARBIDE IS A MUCH MORE HARD, AGGRESSIVE GRINDING COMPOUND WHEN COMPARED TO ALUMINUM OXIDE. ALUMINUM OXIDE TENDS TO BREAKDOWN QUICKER IN SIZE AND IS LESS ABRASIVE TO THE SURFACE. SILICON CARBIDE IS USUALLY THE ABRASIVE CHOSEN FOR SHAPING/WORKING A MIRROR’S SURFACE UP TO 280 GRIT AT WHICH TIME IN MOST MODERN POLISHING SHOPS A SWITCH OVER TAKES PLACE TO THE WHITE ALUMINUM OXIDES LISTED BELOW. THE REASON BEING THAT THE ALUMINUM OXIDE IS LESS AGGRESSIVE AND THE PARTICLE SIZES ARE MORE TIGHTLY CONTROL DURING THE MANUFACTURER’S SEPARATION PROCESS.
