Goldbeater's skin

Goldbeater's skin is a really thin and delicate type of animal skin that is used to make gold leaf. It comes from the outer layer of the intestine of a cow, and is carefully cleaned and processed to remove any fat or other materials.

The reason why goldbeater's skin is so special is that it is incredibly thin and strong at the same time. That makes it perfect for use in the process of making gold leaf, which involves hammering small pieces of gold into extremely thin sheets.

To do this, the goldbeater's skin is stretched out over a special frame and then the gold is placed on top of it. The goldbeater then uses a special hammer to gently tap the gold until it is as thin as possible. This process is repeated many times until the gold has been transformed into a super thin and delicate sheet that can be used to decorate things like furniture or even books.

So essentially, goldbeater's skin is a very special and thin type of animal skin that is used to make gold leaf by hammering small pieces of gold onto it.
