    You can also brighten a ground glass (and its hot spot) by waxing it. "Renaissance Wax" is a good choice. njb

    I guess nothing came of this product. I'll try Renaissance Wax then. Thanks for the tip, Nacio.

    Be careful, you might get a bad hot spot. A thin layer of micro-crystalline wax (or vaseline, or any petroleum product) will vastly increase light transmission but also reduce the level of diffusion. I coated my old ground glass in a thin layer of melted micro-crystalline wax (not polish) and installed a fresnel behind it and it's ridiculously directional, really bright but hard to use with wide lenses.

    My home-built light box also uses micro-crystalline wax sandwiched between glass...and it looks really good but it's a much thicker layer.
