Porcelain and Electricity.
Among the industries that have been profoundly modified by the advent of electricity into daily use is that of making porcelain. Formerly artistic considerations alone governed the various operations of the workmen in porcelain, but now, since this substance is employed for insulators in all electrical installations, scientific processes have been introduced in its manufacture which demand a great deal of secial attention. The exact amont of contraction that the clay undergoes, the exact temperature to which it is submitted in the process of baking, the constant employment of instruments for measuring the temperature and for determining the size of certain pieces — such are among the essentials in the modern art of porcelain making for electric purposes.
