You can purchase it at Amazon as sodium hydroxide or lye, pure lye drain opener, caustic soda , and pure or food-grade sodium hydroxide. Depending on your project, you may be able to substitute potassium hydroxide KOH , which has similar chemical properties and is easier to find. However, these two chemicals aren't the same, so if you make the substitution, expect slightly different results.
If you can't purchase sodium hydroxide, you can use a chemical reaction to make it. You will need:. This is an electrolysis reaction, which proceeds according to the chemical equation:. Another way to make lye is from ashes, as follows:. To make a crude soap from homemade lye, simply combine lye with fat. Once you have lye, use it in a variety of science projects. You can make a sodium hydroxide solution to use as a base, homemade soap , or water glass for homemade "magic rocks," or try the gold-and-silver "magic" pennies experiments.

In building and construction, aluminum is used in materials that enable building facades and window frames. Sodium hydroxide is used in many other industrial and manufacturing processes. It is used to manufacture rayon, spandex, explosives, epoxy resins, paints, glass and ceramics. It is also used in the textile industry to make dyes, process cotton fabric and in laundering and bleaching, as well as in metal cleaning and processing, oxide coating, electroplating and electrolytic extracting.
Due to its strong corrosive qualities, exposure to sodium hydroxide in its solid or solution form can cause skin and eye irritation , according to the U. Workers in facilities where sodium hydroxide is manufactured or used should follow product safety instructions. The U. The National Institute for Occupational Safety and Health provides general safety information about transporting sodium hydroxide, including guidance on packaging and storage, spillage, disposal, and packaging and labeling for workers.
Sodium hydroxide is a highly versatile substance used to make a variety of everyday products, such as paper, aluminum, commercial drain and oven cleaners, and soap and detergents. Sodium hydroxide, also known as caustic soda or lye, is a highly versatile substance used in a variety of manufacturing processes to make other products like paper or aluminum, for example.
