The grinding wheel consists of a disc covered with silicon carbide paper. Water is applied continuously to wash out the sample. There are a number of grades of paper i.e. 180, 400, 600, 800, 1000, 1500 and 2000 grains of silicon carbide per square inch. 180 grades therefore represent the coarsest particles and this is the grade to begin the ...

After the balls were sectioned, their surfaces were ground to remove any damage presented by sectioning. Grinding was followed by etching with a nital solution of 2 ml nitric acid combined with 100 ml of 99.5% alcohol. Subsequently, optical microscopy at magnifications of 100×, 200×, 500×, and 1000× was performed and micrographs were taken.
