In terms of the solid carbon-based material, 'coke' is a residue created when coal is heated up to high temperatures.

The type of coal used to create coke is generally low in sulphur.

What's the difference between coal and coke? Coke is essentially just a derivative of coal. It is produced by humans, and has been used for several purposes throughout history.

The main difference between coke and coal is that, during the heating process, most of the smoke-producing properties of coal are lost.

Therefore, coke is considered to be a 'smoke-free' alternative to coal, and all the uses of coke relate to its ability to burn without creating much smoke.

Interestingly, coke was originally used during the early part of the Industrial Revolution to fuel steam engines because it was considered more 'environmentally-friendly'.

Eventually, society began accepting the need for a cheaper solution - and coke was replaced by regular coal in most industries.

Coke was also regularly used in household furnaces until the advent of electric cookers.
