Kindly say more about corrected grain. Â
As they say in all the cookery programs: "Here is one that I prepared earlier" (posted here on 08/31/2003): What's a corrected-grain virus? Well, I don't know about the virus but "corrected-grain" is a way to make inferior leather look better. "Grain" are the pores on the flesh side of the skin; in a young animal they are very fine and very even. In the older animal they loose that look and also acquire scares from amorous bulls and the general rough and tumble of a cow's life. Therefore you sand off the outer grain layer and create a new surface with rollers, heat, waxes and (usually) a coating of plastic as well. You end up with a high gloss, shiny leather, usually called "bookbinder" or "cobbler", so beloved by nightclub bouncers. That leather does not acquire a patina with wear, it just gets more and more ugly as it gets older. Most cheap shoes, and unfortunately a number of expensive ones as well, are made in corrected-grain.
