    First of all i want to say i have never made or used ground glass, so i have no first hand experience. But i was thinking, maybe it could work if you sprayed the glass with some kind of matte varnish? Either like the ones they use for making frosted glass or some ordinary varnish. Like i said i don't know, just a thought i had.

    I am one of those do it all yourself guys but I withdrew on the groundglass. Commercially made groundglass is brighter than you will ever be able to make yourself and the cost is not dramatically high.
    Buy one. You will not regret it.

    If you happen to be shooting in West Dogpatch and have a busted groundglass, frosted Scotch tape over plain glass or Lexan does a tolerably good job.

    I have made dozens of sheets of ground glass up to 8x10.

    The easiest method is to make two at a time. Obtain some 600 grit, or finer if you can find it. It is available at hobby shops which cater to rock tumblers. Put about 1/2 teaspoon on one sheet of glass. Add about an equal amount of water.

    Place the second sheet of glass on top of the first, and with smooth rotary motion, and only moderate pressure, start grinding. if wheyou check one area has not been ground equally, use a little more pressure in that are as you continue to grind.

    Not difficult, but be patient.

    I agree with Jim, it is so quick & easy to make a very good true ground glass that I don't see the point in a lot of other (and what seem to me to be inferior) methods that folks try. A small bottle of 600-grit silicon carbide from a rock-hound (lapidary) or hobby shop will last you forever and make many, many sheets of ground glass.

    My method is basically the same as described. I've found that hobby shops carry thin glass (thinner than window glass) pre-packaged for use in framing. If you ask nicely they'll usually cut it for you for free, or for a small charge - although that's really not hard to do you yourself either. I take 2 pieces of 4x5 glass, cover one side of each with package tape as smoothly as possible not to make bumps or lumps in the surface, put the grit between with a little water to make a paste and rub them together in a semi-random orbital fashion. I put the bottom one on a piece of flat masonite, or any flat surface and swap them out from time to time so that they both get ground evenly.
    Wash them off occassionally to ck your progress. Takes 15-20 mins max. Wash 'em off, take off the tape, and you've got 2 good pieces of GG.

    And yes, I do plan to buy a new one from Dave soon, too cheap (for that quality) to pass up!
