A briquette's stability was expressed in terms of relaxed density (mass to volume ratio) of the briquette after sufficient time (about 5 weeks) had passed for their dimensions (diameter and length) to stabilize. For the relative durability test each briquette was dropped four times from a height of 1.85 meters onto a steel plate.
