For what it's worth the light box that I sometimes use for bottles & glass is the type marketed to scrapbookers for the purpose of tracing designs, etc (such as the LightTracer II Light Box). This allows muted light to enhance any embossing, designs, etc on the glass while giving a fairly consistent background that eliminates shadow and glare. Depending on the artifact I will either lay it directly on the light box or stand it up as a lit backdrop adjusting the distance as needed. The trick is to not allow the background light to overpower the subject artifact especially for darker colors of glass. I use an entirely different setup for photographing non-glass materials. With that said, I completely agree with Bill - some of the best shots of bottles/glass have been taken outdoors in natural light and you'll just have to try out different lighting/angle scenarios to see what works best with the camera used.

Not only is this a good idea for clarity, try photographing outside the box. The typical archaeological photography setup is nice with the scale, but it frequently does not work well with bottles -- especially on heels or other double-curved surfaces and on colorless glass.
Alternatives include holding the fragment up to a light on the ceiling, taking it outside against a blue sky, or holding the fragment and turning it so that the light reflects from it at different angles. Outside or inside, different backgrounds bring out different glass markings, depending on color, deterioration of the glass, and angles. [I almost made an interesting typo -- angels; of course, those may help too).
The point is to try several different approaches to bring out embossing on glass.

Just a suggestion - try photographing the glass over a light box - this will make all of the embossed letters, symbols, etc come out. If you don't have a light box, you might want to just try holding them up to a window and taking a photo- I've found that this really helps to see the details in the glass. Tim

Unfortunately, even after I downloaded the photos on my computer, magnified the images, and turned them, I still cannot make out enough detail to be of help.
If the colorless glass were cleaned up and if the individual who is looking at the real artifact can tell me what the letters, numbers, and/or symbols are, I might be able to help.
