Book excerpt: Excerpt from The Manufacture of Electric Light Carbons Conductivity is of the greatest importance: the greater the facility with which the current passes, the better the light and the less the required. Thus I think I may state, without experimental data to go upon, but by observation only, that a candle of high conductivity will give as good a light with a 6-ampere current and 38 volts as one of lower conductivity using 42 volts and 8 amperes. Indeed, when the conductivity is very low, the current will not produce the arc, and the carbon becomes intensely heated. This conductivity depends entirely (given pure carbon) on the length of time to which it has been submitted to the firing process. Graphite appears to owe its peculiar condition of high conductivity to its lengthened subjection to Nature's forces, unapproachable by human efforts. Great pressure, continuous and intense heat protracted over long periods, even if possible, would prove commercially im practicable; yet I entertain no doubt that carbon submitted to a white heat, such as would melt wrought iron, for a whole week, would produce a candle more graphitic in character and possessing higher conductivity than one that had been subject to such treatment for a less period. As I deal with the subject of firing, and my special economic arrangements for so doing, this subject will be more fully dealt with.
