Metallurgy - The Art of Extracting Metals from Their Ores

John Percy, a founding member of Resistance and the Democratic Socialist Party, was national secretary of the DSP during the period covered by this volume. His reports included here document the campaigns and activities of the DSP when it was the largest organisation on the Australian left.

This is an 1873 manual on the art of extracting metals from ore. Including a vast amount of invaluable information and helpful diagrams, this comprehensive handbook will be of utility to anyone with a practical interest in metal extraction. It would make for a fantastic addition to collections of related literature. Contents include: ¿Definition of Metallurgy¿, ¿On Certain Physical Properties of Metals¿, ¿Physical State¿, ¿Action of Heat¿, ¿Specific Gravity¿, ¿Crystallization¿, ¿Varieties of Fracture¿, ¿Elasticity¿, ¿Malleability¿, ¿Ductility¿, ¿Ores¿, ¿Reduction¿, ¿Smelting¿, ¿Modes of Formation of Silicates¿, etcetera. Many antiquarian texts such as this are becoming increasingly rare and expensive, and it is with this in mind that we are republishing this volume now, in an affordable, modern, high-quality edition. It comes complete with a specially commissioned new biography of the author.
