Some of the quality parameters are related to the production process, e.g. the stone powder content, the clay lump content, even the gradation can be adjusted by manufacturing process. And some qualities mainly result from the resource of the sand, e.g. the particle shape, the surface texture, which are the substantive characteristics of the MS.
