Soaps
- Soaps are made from fats or oils mixed with a strong alkali such as sodium hydroxide.
- The process of making soap is called saponification, where the fats are hydrolyzed into glycerol and fatty acid salts.
Glass
- Glass is primarily made from silica, which is melted at high temperatures along with other minerals to form a molten glass.
- The molten glass is then shaped and cooled to form solid glass objects.
Ink
- Ink is made from a pigment, a binder (such as gum arabic or shellac), and a solvent to make it flow.
- Different types of inks are made for different purposes, such as writing, printing, or painting.
Cement
- Cement is made by heating limestone and clay in a kiln to form a product called clinker.
- The clinker is then ground into a fine powder and mixed with gypsum to make cement.
Paint
- Paint consists of pigments, binders, solvents, and additives.
- The pigments give color, the binders hold the pigment particles together, the solvents make the paint flow, and additives improve properties like durability or finish.
Safety Matches
- Safety matches are made from a mixture of sulfur, potassium chlorate, and an adhesive binder on the match head.
- When struck against a rough surface, the match ignites due to the friction and the chemical reaction between the sulfur and potassium chlorate.
Gunpowder
- Gunpowder, also known as black powder, is made from a mixture of sulfur, charcoal, and potassium nitrate.
- When ignited, the gunpowder rapidly burns and produces gases that create pressure to propel a projectile out of a gun.
