Retention of Shape

The quality of retaining its shape in the fire is very important and depends on the properties of both the coal and the binder used in making the briquette. This point is discussed more fully in connection with the various coals and binders examined. The principle involved is very simple. The binder must hold the coal particles together until they are sufficiently softened to cohere.
The temperature at which different coals soften or cake together varies greatly.
