Blended sand is made by adding a bond to a ‘washed and dried’ or unboned base sand. This unbonded sand is sometimes called ’sharp sand’, however, the name has nothing about the actual grain shape. The unbonded base sand may be silica, olivine, zircon and others. Each sand has properties that make its use desirable in certain situations [8].
