Physicochemical and mineralogical properties of clays used in ceramic industry at North East Colombia

General properties of clays from Ceramica Murano Mine, in the municipality of El Zulia, Norte de Santander, have been investigated. Five clay samples were collected from different mantles of the mine. All the samples were characterized using chemical and mineralogical analysis, as well as physical properties like particle size, plasticity, drying and firing shrinkage and water absorption capacity. The chemical and mineralogical results indicated...
