Is ebony floating on the water really ebony?

Ebony is a part of trees buried in the soil, which is formed by carbonization for thousands or even tens of thousands of years under the conditions of hypoxia and high pressure, under the action of bacteria and other microorganisms, so it is also called "carbonized wood"

Ebony is hard, mostly brown-black, black-red, gold and yellow-brown. Its section is smooth, the wood grain is fine, and the mirror brightness can be achieved when properly polished. Some ebony trees are similar in nature to rosewood, and do not fade, decay or be eaten by insects. It is an ideal material for making artworks and antique furniture.

There are many kinds of ebony, mainly including: willow, green bar tree, camphor tree, Phoebe bournie, Toona sinensis, red bean bin, coriaria, willow, phellodendron amurense, Sophora japonica, sandalwood and so on. Generally, ebony can be formed by tree species with fragrance and bactericidal properties.

So whether ebony can sink in the water mainly depends on the material of ebony and the environment when ebony is formed. Compared with the sinking wood and ebony formed with water in the river bed silt, it is basically sinking. However, some ebony trees formed after dry land was formed due to geological changes later, except for varieties with a large proportion of wood, will not sink. Whether Jin Sinan will sink or not is not the standard to distinguish whether it is ebony!
