Stuff of Progress: Iron

Iron in the Modern Age

  • As the tools to produce steel got refined, they were made more energy efficient and produced higher-quality steel.
  • The production of finished iron in 2018 is 1.8 million metric tonnes, as compared to 800,000 metric tonnes in the 18th century. China accounts for one of the leading producers of steel.
  • The modern civilization is highly dependent on iron exploration and we continue to find newer ways to manufacture the metal with a minimum carbon footprint.

The discovery and use of Uranium
The discovery and use of Uranium

Uranium was first used as a coloring agent in the manufacture of pottery. As early as 79 CE, naturally-occurring uranium oxide was ground up into a yellow powder and applied as a pottery glaze.

Uranium and electrical energy
  • Uranium is energy-dense. In 2018, uranium powered nuclear reactors produced 2,700 terawatt-hours of ultra low-carbon electricity. One terawatt-hour of energy is equivalent to the annual energy consumption of 27,000 European citizens.
  • Electricity production from nuclear energy is one of the cleanest forms of energy production, even when nuclear waste is taken into account. Nuclear waste storage is currently resulting in little mortality and illness, as the waste is contained within the grounds of the nuclear power plants themselves.

Chemical disinfection is vital

Chemical disinfection has helped to improve life expectancy and considerably changed our collective standard of living.

Early chemical disinfection

Basic chemical disinfection was employed since at least 3,000 BC, using alcohol, elemental copper and Sulfur, salt, sodium carbonate, and mild organic acids.

Sulfur fumigation was used widely throughout Europe through the Middle Ages, especially during outbreaks of plague. But disinfectants such as compounds of Sulfur, mercury, and copper were only moderately effective and highly toxic, resulting in health problems.

Effective deployment

The first notable effective deployment of disinfectants came in 1675 when a Dutch scientist noticed through the glass of his microscope that strong vinegar killed microorganisms.

In 1887, a British surgeon researched the effects of carbolic acid as a disinfectant in the operating theater. The results drastically reduced infection rates among patients.
