Microwave oven
Japan's Sharp Corporation began manufacturing microwave ovens in 1961. Between 1964 and 1966, Sharp introduced the first microwave oven with a turntable, a feature that promotes convenient even heating of food. In 1965, Raytheon acquired Amana. In 1967, they introduced the first popular home model, the countertop Radarange, at a price of US$495 ($ in dollars).
Solvay Process Company
The Hazard family invested in an affiliated business, the Semet-Solvay Company, formed in 1895. Louis Semet, a relative of Ernest and Alfred Solvay, had developed with the brothers a coke oven designed to recover valuable materials formerly wasted in the coking process. In 1892 the Solvay Process Company built the first of the ovens in America, forming the Semet-Solvay Company three years later to build and operate them. Coke plants were located in Ashland, Kentucky; Buffalo, New York; Detroit, Michigan; and Ironton, Ohio. Semet-Solvay operated its own mines in West Virginia, providing much of its coal supply.
