Observation of Calcite in Solution (1)

Observation of Calcite in Solution (1)

The growth process of calcite crystals in solution was observed. Crystal growth starts from the kind of etch pit shown in (a-1), passes through the state shown in (a-2), and then the whole area is covered in steps, as shown in (a-3), hiding the etch pit. It took approx. 15 minutes to go from (a-1) to (a-3).
