Regular : Plain old clear glass
Non-Glare : Plain old glass, acid-etched on one side to reduce glare. Also known as reflection control. Don't use on art with more than two mats or fillets, otherwise there will be too much distortion. Also really stinks on fabric mats.
Conservation : Coated on one side to filter out up to 97% of damaging UV radiation. The coated side scratches easily, so it goes on the inside toward the artwork.
Conservation Reflection Control : UV coating on one side, etched on the other.
AR Glass : Anti-reflective, coated with a quartz-type (I think) coating to virtually eliminate reflections. Beautiful stuff, but very pricey and can be a bugger to clean. Used to be known as Den Glass.
Museum Glass: The Rolls Royce of glass. All the same properties of AR glass but with a UV coating on one side.
Water White Glass: Available with or without UV coating. It's glass made with a low iron content, which greatly reduces the greenish cast of other glasses. But since it has less iron, it can be a bit weak and brittle.
Perfect View ? : Or something like that. A hybrid of reflection control and AR glass, made to be an option for a price point between the two. Etched on one side, coated on the other. Available with or without UV protection.
Confused yet? Just wait!
Then there's acrylic glazing, aka Plexi! Good for large pieces to reduce weight and chance of breakage. Great for kid's rooms or high-traffic areas such as schools, offices, restaurants and prisons. Don't use it on pastels (static) and don't clean it with paper towels (it'll scratch.)
You can get it in:
Regular
Non-glare
Conservation
Conservation non-glare
AR Gotcha! In this case AR means Abrasion Resistant. Means it's a lot harder to scratch it.
Check out
Tru-Vue's website and
Cyro's for more information. Take a look in the Grumble for past threads about handling and cleaning plexi and AR glass.
I noticed that some of these terms, such as Reflection Control and Museum Glass are trademarked by Tru-Vue, but have become almost generic terms. Guess that comes with being the biggest name in the industry. Sort of how Kleenex and Q-Tips must feel.
