why ashes don't disappear

Ash is the powdery residue left behind after something combustible is burned. It consists mainly of carbon, along with various other trace minerals and impurities depending on what was burned. Ashes are commonly associated with the remains of organic material such as wood, paper, or leaves after they have been burned. They are often grayish-white in color and can be fine or coarse depending on the burning process and the material being burned.
