True Geology: Sodalite Syenite

Blue Bahia is commercially sold as granite, but it is geologically a sodalite syenite. This distinction matters because true geological classification determines the stone's actual physical and chemical properties — which affects how it performs, how it should be maintained, and how it reacts to acids and moisture.
