Surprisingly, there are actually quite a few types of picture glass. See, told you you'd be surprised. First of all, there are several glass types. There is plain glass, UV blocking glass, and no-glare. Additionally, you can get UV blocking and no-glare, all in one convenient picture glass. UV blocking? Isn't that for sunglasses? Why yes, yes it is. And that is because it can be damaging to your eyes. Likewise, UV light can damage art inside of picture frames. UV light can make pictures fade with age, and distort colors.
The second type of picture glass is acrylic. This is an artificial glass product. Acrylic picture glass has many advantages. One of the biggest ones is that it's more durable than glass. If you drop a picture frame, acrylic is less likely to shatter. This doesn't mean it won't shatter, it just means that it can stand more pressure. Also, acrylic picture glass is usually cheaper than regular glass. Much like acrylic, plexiglass is an artificial picture glass that can be substituted for regular glass. Both of these types also come with UV blocking and no-glare.
So which type of picture glass is for you? That depends mainly on two factors. Where are you hanging your art? What type of look are you going for? If you are hanging your art in a safe place with little to no sun, glass may be the type for you. If you have the opposite of the above situation, I'd recommend one of the artificial glass. Also, the type of picture glass you choose has a slight effect on the look of your art. Glass looks, well, like glass, and an artificial glass can look plastic-like. This isn't a HUGE deal, but if it makes a difference for you, go with glass.
I'm going to go off-topic a bit and talk about hanging picture frames. Hanging picture frames is a very simple task which should only take a couple seconds. However, a problem presents itself when dealing with the elderly. How can they hang a picture frame when they sometimes can't even walk? Luckily, there are some methods to doing this. First is, hang it lower. Yeah, that's pretty obvious, but it's the easiest fix. If you're unable to hang a picture frame at the height you'd like, you can always resort to mechanical means. A good way to hang a picture frame high up without climbing a ladder is to use electric lift chairs. These can be fairly expensive, but they have many other uses besides picture frame hanging.
That's it for today's post. A fairly basic topic, but one I felt should be covered anyways. Remember, if you're looking to purchase a glass picture frame, you don't need any type of picture glass. The whole frame is glass, so it doesn't matter. Anyways, thanks for reading, and good luck in all your picture framing exploits! :)
