Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.

As Ash noted in 1963, the actual methods used to fire a blast can dramatically change the powder factor. This is looking at the way the rock will break based on the free faces, which, for a typical production blast, will be influenced by the layout of the drilling pattern, the burden and spacing of the blast, as well as the timing of the blast.
