· There are about 25 tests that can carry under sand testing. Basic sand tests can measure tensile strength, friability, moisture content, permeability, green compression strength, compact ability, loss on ignition, volatiles content, grain size and distribution and many more. Each test obtained very specific characteristics of the sand.

The silica gel should never go dry until the procedure is complete. Place a thin layer of sand on top of the silica gel (Figure 1). Using a pipette, wash down any sand that may have stuck to the sides of the column. Drain any additional solvent until the sand is dry, but not down to the silica gel layer. Figure 1.
