New Process of Making Lampblack

New Process of Making Lampblack

The Chief Chemist of the Goodyear Tire & Rubber Company in a recent statement gives the following particulars relative to the new process of making lampblack. He says now there are practically only two kinds of lampblack, gas and oil, made by burning natural gas or petroleum oil. And the process, strangely enough, is just the same in principle as the old one that gave lampblack its name, because it was deposited on lamp chimneys when lamps burned smokily. The West Virginia and Oklahoma oil fields produce most of the country’s lampblack now. There are two general processes. In one, the oil or gas flame is directed from below against the outside of a revolving steel cylinder. The lampblack is deposited on the cylinder, and scraped off by a scraper as the cylinder goes round. In the other the flame is directed into a series of connecting brick compartments. Some lampblack is deposited on the walls of the first compartment; a finer and fluffier grade in the next compartment as the air carries it along, and so on to the end. Some difficulty is experienced in rubber factories in handling this coloring material. It is so light and fluffy that unless the greatest care is taken it spreads over everything accessible and the workers in it resemble real Ethiopians most of the time. The demand for lampblack for coloring tires has advanced its markets price 40 per cent, in a comparatively short time, and it is safe to say that no one could now go on the market and buythe industry’s requirements for the next year. It simply isn’t made fast enough.
