– The history of iron tip soldering since 19th century – Soldering itself has a history of 6000 years, and iron tip soldering was already in 1860''s. Burning iron tip soldering was the main method at that time. It was replaced by electric tip during the 1920s, around the time radio broadcasting began.

Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.

Outdoor grilling is a popular cooking method, primarily because of the wonderful taste it imparts on meats. It can also be a healthy alternative to other cooking methods, because some of the meat''s saturated fat content is reduced by the grilling process. However, grilling also presents a health risk.
We have employed a combination of traditional foodprocessing and preparation practices, including the addition of animalsource foods, notably fish, in 2 communitybased trials among weanlings and young children in rural Malawi. Details of these strategies and their implementation have been published earlier (24,26,29,30).
Instead, the iron heats up into a spongy mass containing iron and silies from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silies into the iron metal to create wrought iron. Wrought iron is hardy and easy to work, making it perfect for creating tools.
The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low H2S concentrations (300 ppm) operating at low to moderate pressures (50500 psig).
