When you look at the history of an artist using Dichroic coated glass, it appears that the artist has been under the major handicap of not having any information on what he or she was working with. These artists were exposed to a piece of glass that had interesting color effects, but came from a very complex and scientific industry not easily understood. These “high-tech” coatings were capable of reflecting a narrow band of light (or one color) and at the same time, transmitting the remaining part of light. The coating process is completed in a vacuum deposition chamber by vaporizing quartz and metal oxides with an electron beam gun and condensing micro thin layers on the surface of the glass in the form of a crystal structure. This coating that we commonly call Dichroic glass today, is actually an “interference filter” permanently adhered to the surface of a piece of glass. The technology used to manufacture the optical interference filter has been in existence for many years. It is known as “vacuum thin film deposition.”
WHAT ARE THESE THINGS?
You have probably started to notice these little boxes popping up everywhere. So what are they? This particular design is called a QR (Quick Response) Code. It is a 2D barcode that when scanned by a smart phone, takes the user to a web site or other information.
What type of information is available through a QR code? A QR code can link to a web site, a video hosted on a web site or text information.
To access a QR Code requires a smart phone, such as the iPhone, Droid, etc. and a free downloadable app from a company such as this: http://www.i-nigma.com/Downloadi-nigmaReader.html The app is free! Once you have downloaded the app, activate it and your smart phone camera will become a scanner. Scan the above QR Code and you will be taken to the Home Page of the Coatings by Sandberg web site. It’s that easy!
To create a code is just as easy and also totally free. Here is one such company that offers this service: http://qrcode.kaywa.com/
Check out the history on these codes: http://en.wikipedia.org/wiki/QR_code You will be surprised at how long they have been in use and what they are being used for.
