Summary: Until the 17th century, the building blocks of the natural world were a mystery. Of elements there were believed to be four - air, earth, fire, and water - and the science of chemistry had yet to be born. This program identifies some of the first chemical elements to be discovered by spotlighting the work of Hennig Brandt, Robert Boyle, Henry Cavendish, Joseph Priestly, Antoine Lavoisier, and...

Summary: Iron ore is reduced and manufactured into steel in a modern plant where, in a continuous process, ore is crushed and mixed with coke and then fed into the top of a blast furnace. Molten iron flows off from the bottom; slag is skimmed off; and iron is converted to steel by blowing oxygen through it to remove residual carbon, adding lime and magnesium powder to remove other trace solid...

Summary: Because of its wide availability, NaCl is the starting material for many inorganic chemicals. In this program, salt is seen being pumped to the surface from deposits of 1011 tons in salt fields as a brine solution, and into a chemical plant where chlorine and sodium hydroxide are produced by electrolysis. Three types of cells used to separate the products at the anode and cathode-mercury...

Summary: Limestone, or calcium carbonate-made of the skeletons of billions of sea creatures-is mined in large quantities. Carefully blasted out of the ground, it is first crushed with huge pestles to eliminate large boulders, then passed through a series of sieves to separate large chunks for further crushing. When sufficiently small, it is washed to remove clay, dust, and sand. The grades are...
