Need help with my writing homework on Inventors and Important Scientist of Explosives and Their Developments. Write a 2500 word paper answering; Till then it was used for making fireworks, firing guns, blasting in mines. Later, it was taken over by more efficient explosives. However, antique gun enthusiasts and special effects specialists still use them. Black powder is manufactured by mixing and grinding 75% potassium nitrate, 10% sulfur and 15% charcoal to create a uniform powder. Sulfur in the gun powder is a corrosive compound and tends to erode gun pipe when it burns.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Records suggest that gun powder was shipped from Ghent to England in 1314. Black powder had its peaceful uses in Europe, especially in Germany, Hungary, during the 17th century. Its first application in civil engineering works was made in 1679 while making the Malpas Tunnel in France.&nbsp.Almost 15 years later, the Swiss inventor Immanuel Nobel and his son Alfred began exploring about its commercial uses.George Mowbray&nbsp.&nbsp.&nbsp.&nbsp. Manufacturing of nitroglycerine on a large scale in the US is in the name of George Mowbray. Mowbray built plant of nitroglycerine near North Adams for the construction of the Hoosac Tunnel. Pure Nitroglycerin freezes at about 52 degrees F, and therefore it is easy to store in ice packets. He produced and supplied nearly 1,000,000 pounds of nitroglycerine without any accidents. In the US, nitroglycerine was used to blasting oil wells to increase the oil flow, and therefore its use was widespread in the oil industry. Due to its low cost, it is still sometimes used where oil flow is required from small wells (Explosive, 2014).R.S Penniman&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Contribution of Penniman from the US was in modifying nitroglycerine. He devised ways to coat the ammonium nitrate with paraffin. This prevented ammonium nitrate from picking up moisture resulting in ammonia dynamites in the market (Explosive, 2014).Immanuel Nobel and Alfred Nobel&nbsp.&nbsp.&nbsp.&nbsp. Immanuel Nobel and Alfred Nobel, the father-son duo and Swedish nationals made rigorous efforts between 1959 and 1961 to improve nitroglycerine so that its use can be made in mining and blasting rocks.&nbsp.&nbsp.&nbsp.&nbsp. In 1862, they developed crude processing facilities at Heleneborg, Sweden. Though Alfred developed relatively safe processing facilities, yet it exploded in 1864 killing his youngest brother Emil Oskar along with others. Later, he erected facilities in Sweden at Vinterviken near Stockholm and another one at Krummel, Germany. He also built one more plant in Norway.&nbsp.
