Where to put a glass piece so it is actually seen

Glass has no colour of its own in shadow. Where you put it matters more than with almost any other object.

Light behind, not in front

A window sill, a shelf with a lamp behind it, or a cabinet with a light inside all send light through the piece, which is what makes colour and bubbles visible. A spotlight aimed at the front does the opposite.

Give it a plain background

Patterned wallpaper reads straight through clear glass and turns it into visual noise. A plain wall, a block of book spines or a dark surface behind gives the outline something to sit against.

Group by height, not by colour

Three pieces of different heights in one group read as an arrangement. Three of the same height read as a row. Small vessels in particular want grouping.

Keep it off the daily route

Hallways, the edge of a kitchen counter and low tables near doorways are where pieces get knocked. A shelf slightly above eye level is safer and shows the piece better.
