At this point I would like to make something understandable. What we are discussing about here are Glass Dining Tables that have a clear glass top. This is not the case however for all glass tables. They can have frosted glass tops or even colored glass tops.
However, the tips I’m giving you concerning lighting, mostly work for a clear glass tables. Side tables are also furniture that will look great with a glass top and the same thing I mentioned before applies here as well. Place your glass side table in such a way that a source of light (a lamp, the sun etc.) reaches the top of your table.
