There are as many different ashes as there are different things to burn.
Typical ash from a piece of wood mainly consists of potassium (bi)carbonate and coal, besides minor other components (mainly carbonates and sulphates from calcium and magnesium).
When extracted with water, the solution is basic and contains mainly potassium bicarbonate.
By the way, this is the process that gave potassium its name: Extraction of wood ash in big pots.
Ash is a fine, powdery residue left after combustion. It is usually light grey in color and can vary in texture from gritty to smooth, depending on the source material. Ash is typically non-toxic and has a high pH level.
Chemical nature or chemical properties of the wood
Ash isn't a property of any sort. It is a form of matter containing a variety of substances each with its own set of physical and chemical properties.
If it's a chemical, it has chemical properties. An oreo churro (whatever unholy abomination that might be) is a mixture of chemicals, each of which will have their own chemical properties.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.

The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.

Chemical properties are determined by experiments.

Many chemicals.
Chemical changes involve the breaking and forming of chemical bonds, resulting in the creation of new substances with different chemical properties. Examples include burning wood to produce ash, or combining hydrogen and oxygen to produce water. These changes are often irreversible and accompanied by a transfer of energy.
