On a commercial scale, gelatin is made from by-products of the meat and leather industry, mainly pork skins, pork and cattle bones, or split cattle hides. Contrary to popular belief, horns and hooves are not commonly used. The raw materials are prepared by different curing, acid, and alkali processes which are employed to extract the dried collagen hydrolysate and which may take several weeks. The worldwide production amounts to 250,000 tons per year (roughly 500 million lbs).
As for home cooking, boiling certain cartilagenous cuts of meat, or bones, will result in gelatin being dissolved into the water. Depending on the concentration, the resulting broth, when cooled, will naturally form a jelly. This process may for instance be used for the pot-au-feu dish.

Gelatin (also gelatine) is a translucent brittle solid substance, colorless or slightly yellow, nearly tasteless and odorless, which is created by prolonged boiling of animal skin, connective tissue or bones. It has many uses in food, medicine, and manufacturing. Substances that contain or resemble gelatin are called gelatinous. Gelatin is also known as E number E441.

That's what I learned some time ago. You know that you can purchase gelatin specifically for hair, skin and nails. Interesting huh?
