The Legacy of Puddled Iron in Contemporary Metallurgy

The Legacy of Puddled Iron in Contemporary Metallurgy

Apr 1, 2024

Puddled iron is a refined form of iron produced through a process known as puddling. It was a significant technological innovation during the early stages of the Industrial Revolution, providing a method to transform crude pig iron into a more malleable and durable material suitable for various applications. The puddling process involves melting pig iron in a reverberatory furnace and stirring it with rods, which oxidizes impurities such as carbon and silicon, resulting in a more refined iron product.

Olfactory Indicators

Olfactory Indicators

Jul 26, 2023

Olfactory indicators, also known as smell indicators or odor indicators, are substances that change their smell in the presence of certain chemicals or conditions. They are commonly used in chemistry experiments to detect the presence or absence of specific gases or to determine the pH level of a solution. Olfactory indicators provide a visual and olfactory cue, making it easier for scientists to identify and analyze substances.

From Kaṇāda to Rutherford: Tracing the Evolution of Atomic Theory

Jul 15, 2023

The evolution of atomic theory is a long and winding road that has been travelled by some of the greatest minds in history. It began with the ancient Indians in 600 BC who gave the concept of “Parmanu” to Greeks who first proposed that matter was made up of tiny, indivisible particles. The 19th and 20th centuries saw significant advances in our understanding of atoms.
