Clay soils are essential raw materials in the ceramics industry. But how do manufacturers determine the potential of soils for industrial use when scoping out a new clay pit? An open-access study by three researchers in Mozambique shows how they evaluated soil potential based on samples extracted from the Manjacazi district.
