Mike, that is a good summary of the varying parameters for making vinyl discs. I used to run a vinyl compounding plant that produced (or at least tried) vinyl for records, among other products such as cable jackets. The common "brightener" is titanium dioxide and the common "blackner" is carbon black, the quality (mostly size of particles, which can vary greatly) of these being the main contributor to the noise qualities of the discs. The dyes can also contripute if the pigments in the dye are of poor quality.
It is very difficult to discern whether a vinyl is virgin or not through visual or tactile observation, much like a woman I guess.
TWL, it appears that I might have more intimate knowledge of vinyl than you suspected - love the smell!
