Serpentine
ID: serpentine
(Mg, Fe)3Si2O5(OH)4
Description
Serpentine denotes a group of polymorphous minerals classified as hydrous magnesium iron phyllosilicates. Characterized by their layered sheet structure, these minerals are frequent products of metamorphic alteration in ultrabasic rocks. In the context of ceramic materials, serpentine is noted for its high magnesium content; however, it is rarely utilized as a primary raw material in standard ceramic bodies due to its complex thermal behavior and potential for structural instability during firing. Its inclusion in glazes is similarly limited, as the mineral's chemical composition and firing characteristics typically necessitate careful processing to prevent undesirable surface defects or excessive fluxing effects.
