In 1911, after Thomas A. Edison had designed forms for a monolithic concrete house, he attempted to cast furniture of concrete. The first piece of furniture he cast was an elaborate phonograph cabinet, patterned along the lines of the model which was being used in his successful "talking machine." In casting the cabinet, Edison employed smooth, nickel-plated molds, designed for this purpose at Menlo Park. The concrete mixture, similar to that which he used in his monolithic houses, contained a special additive, a jelly-like substance which gave good workability and a smooth finish. When cast and dried, the concrete phonograph cabinet was painted with white enamel and trimmed in gold. The cost of the Edison concrete cabinet was $10. The low cost was the feature which he believed would ensure the acceptance of the furniture.
