Bulb of applied force

In lithic analysis, a subdivision of archaeology, a bulb of applied force (or bulb of force) is a defining characteristic of a lithic flake. When a flake is detached from its parent core, a portion of the Hertzian cone[?] of force caused by the detachment blow is detached with it, leaving a distinctive bulb on the flake and a corresponding flake scar on the core. Bulbs of applied force may be distinctive, moderate, or diffuse, depending upon the force of the blow used to detach the flake, and upon the type of material used as a fabricator. Generally, the harder the material used as a fabricator, the more distinctive the bulb of applied force.
