Early excavations used hand drills and black powder. The late 1860s saw the invention of dynamite and the mechanical rock drill. They supported underground workings with wooden timbers, the best known of which is the "square-set timbering" invented in 1860 on the Comstock, and unexcavated rock pillars or the "shrinkage" system by the beginning of the twentieth century. Early miners hand carried ore or used simple machines such as windlasses, whims, or small steam engines. Deep mining on the Comstock in the 1860s and 1870s introduced new hoisting technologies such as large steam engines and high-speed cages. A system of air passages connected to the outside ventilated some mines and others used hand bellows or engine-powered fans. Early mines drained underground workings with tunnels or bucket bailers. Deep mining on the Comstock introduced large, steam-powered Cornish pumps

(1) Absorption and diffusion of carbon into solid ferrous alloys by heating to a temperature usually above Ac3, in contact with a suitable carbonaceous material. A form of case hardening that produces a carbon gradient extending inward from the surface, enabling the surface layer to be hardened either by quenching directly from the carburizing temperature or by cooling to room temperature, then reaustenitizing and quenching. (2) The process by which carbon diffuses into the steel. The process can be deliberately induced by appropriate treatments. It can occur accidentally during some manufacturing processes with potentially adverse consequences for the component

The solids present in the must are removed before or after fermentation for white wine production. Fining is achieved by combined processes including filtration, centrifugation, flocculation, physicochemical treatment (e.g., activated carbon, gelatin, etc.,), and stabilization to prevent turbidity formation (e.g., the use of bentonite, cold stabilization techniques, etc.). Clarification leads to the separation of sediments via racking
