Interior design has evolved over the decades and indeed centuries. Trends and materials have moved into and out of fashion and availability, and it is possible to identify different periods of history from decor alone. It has often been the case that interior design fashion was influenced by the aristocracy and glassware has always been an important part this. Good pieces of glass have always had some level of expensive attached to them and this has meant they have always been considered something of a luxury. Because glass has always been associated with good form (often over function), it has remained a staple ingredient in many interior design work. But how do you get the most out of it?
Minimising colour scheme. Whilst coloured glasses can look very attractive, it is all too easy to get carried away and mix too many colours of glass-vases or glass bowls together for example. If you don't want to end up with your rooms looking there has been a paintball fight going on in them, you should not go crazy with the colours. It is a much better idea to stick to two or three colours or use different shades of one colour scheme.
Use to improve light. The ability of glass to refract light entering a room and re-distribute it in multiple directions has made it a very valuable tool or manipulating light. Of course this is most effective when the glass is thinner and has lower levels of pigment, but thicker glass can still work when the light is quite intense. In rooms with low light, you can place some vases or wine glasses near the window and it will help move the light deeper into the room, and avoid it being concentrated in only one area.
Mix with opposites. It is often the case that opposite work well together in interior design. Glass is well known for having a shiny and polished finish, and with this in mind it often works incredibly well in interior design when placed alongside less reflective and more rough materials. A pair of whisky-glasses and decanter set to a background of concrete or brushed steel works really well for example. Or what about using a glass chandelier against an artex ceiling (not that artex looks good)?
