Clastic sediments are distinguished on the basis of average grain size. gravel-size particles are larger than 2 mm diameter sand-size particles range in diameter from 1/16 to 2 mm (they feel like sandpaper) silt-size particles have diameters from 1/256 to 1/16 mm (they feel finely gritty) Siltstone is a fine-grained detrital rock composed of clay and silt-sized particles. The silt particles in siltstone commonly feel more abrasive than finer clay particles. Geologist commonly grind a small amount of the material between their front teeth; it feels gritty if it is siltstone and feels slippery or smooth if it is shale or mudstone).There are various physical properties of Siltstone like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it.
