A combustible carbonaceous briquette, having a high bond strength and good burning characteristics is formed by adding to the carbonaceous material a composition containing from about 80% to 99.9%, by weight, of sodium bentonite, from about 0.1% to 5%, by weight, of a water soluble acid polymer (i.e. having a carboxylic acid, salt thereof or anhydride thereof) and preferably from about 0.1% to 5%, by weight, of a water soluble dispersing agent. A combustible carbonaceous briquette formed from about 90% to 99% of carbonaceous material and a binding effective amount of the binding agent composition to form a briquette which has high strength, will not easily crumble or disintegrate and has good burning characteristics.
