This layer is used to coat materials that entered into the oyster shell that may consist of foreign objects such as sand and other materials. These foreign objects can cause injury to the soft parts of the oyster, so it needs to be overlaid with 'nacre' also known as 'mother of pearl'. This material can be seen on the inside of an oyster shell or other shellfish.
