Hardware store....they do have glass, and its ok, but can have a greenish cast, and is often somewhat second rate.
Clear glass...just that, clear, usually comes cleaned and is a better, more clear and less imperfections than the hardware variety.
White water....clear but has absolutely no green cast to it. A higher grade of clear.
UV....clear, but with a coating that blocks most UV light. Still has glare.
Then it starts into the glass types that reduce glare, which can be a big issue if the painting is hung in certain places, or especially if the painting is mostly darker in value.
Non glare...the old style of glass that has a frosted etched surface, but can make a painting look hazy and foggy.
Reflection control....has a coating on it to all but make the glare disappear. I very much like this type, "ultra view" by Tru Vue is the brand/name.
Museum...is like the reflection control but blocks 97% (or more?) of the UV light. Best glass of all, but at a very premium price.
I mostly use ultra view, due to the cost vs. quality. It does block some of the harmful light, and I feel its adequate for most situations.
I hope this answers a few questions, if not, ask away!!!
On another note, I sadly missed a fun paint out last weekend, and will be a student at a workshop in a couple weeks, so decided to get in some plein air on my own. I live in a very beautiful, peaceful place and love taking advantage of it in pastel!
