Although the main chemical components of all types of ivory are almost the same, the size and shape of the crystallites of dahllite and their arrangements in the dentine mass are found to vary in different types of ivory.
Like collagen, dahllite also shows chemical changes due to the fact that elements from the soil infiltrate into the micro tubules of dentine and react with the crystals of carbonate hydroxyl apatite.
The paste crystallizes largely as carbonated apatite, or dahllite, a mineral that occurs naturally in the human skeleton.
