Aragonite

Description

Aragonite is a carbonate mineral that serves as one of the three primary naturally occurring crystalline polymorphs of calcium carbonate, alongside vaterite and calcite. Chemically identical to its counterparts but distinguished by a unique crystal structure, aragonite is generated through both physical and biological mechanisms, often manifesting via precipitation within freshwater and marine ecosystems. In the context of ceramic science and glaze formulation, aragonite functions as a source of calcium, influencing the melting behavior and textural development of vitrified surfaces. Due to its distinct crystalline arrangement compared to the more common calcite, it possesses specific thermal decomposition characteristics that ceramicists must account for during firing processes to achieve desired fluxing effects and finish.
