Episode overview
Different rubber compounds are mixed and assembled with reinforcing fabric, steel belts and tread before being moulded and vulcanized into car tires. Fine filaments are unwound from silkworm cocoons and combined into thread; conservators clean, stabilize and repair ageing works of art; and high-pressure metal cylinders are formed, heat-treated and tested to produce scuba tanks.
