Personally there is not one proper way to display art glass, because the right way needs to look good to the beholder of the sculpture.
There are two types of glass, opaque glass art which is best lit from an angle or on top of the piece.
Transparent or translucent glass looks great with natural or artificial lighting that is direct or reflected.
Niches with lighting can really frame the piece and give the sculpture the main attention within any interior.
These are just a few examples from our customer’s displays within their residential homes that really look wonderful.
