Harding Mine's Many Contributions to Industrial History. Soon after mining began in 1919, the Harding Mine was shipping 800 tons of hand-cobbed lepidolite annually, along with smaller amounts of rose muscovite and spodumene. Then in 1924, two shipments were found to contain a mineral contaminant that was detrimental to glass-making.

The results show that magnesium could delay the precipitation process and increase the quantity of the precipitates. As the magnesium content increases, the crystal morphology of precipitates changes from calcite to Mg-calcite, vaterite, rosette and nesquehonite. Cementation effect in the Ca-rich group is superior to that in the Mg-rich group.
