If you are framing to deliver a portrait, you can use regular glass. It is nearly as good as (but not quite) as UV protective glass. Plexiglass, which is often a requirement in shipping a painting to a show, offers no UV protetion. It just doesn't make people worry about breakage.

Non-glare glass, in order to perform at its best, requires the surface of the image to touch the glass. With original work, (any work worth framing in my regard) this simply cannot happen.

There are a number of new glasses on the market that minimize glare; you will need to look at each option, as many of them "fog" out as you move off the perpendicular.

Do not underestimate the negative aspect of static charge. Without a special anti-static spray (used instead of something like Windex), your loose pastel dust will fly to the plexiglass and be EXTREMEMLY aggravating.

When you use this kind of spray (or any spray) be SO very gentle, as the tiniest swipe can scratch the plexiglass.
