The short answer
Use translucent (cathedral/stained) colored glass for a mosaic lamp, because the globe is backlit — light has to pass through the glass to glow. Opaque tiles look dull when lit. Aim for ~1/8-inch glass that cuts cleanly with wheeled nippers, in small pieces that sit flat against the curve.
Translucent vs opaque
Translucent glass lights up in rich jewel tones; opaque glass blocks the light and goes flat. For a lamp, translucent wins almost every time — mix a few opaque accents at most.
What to look for
- Stained/cathedral glass, ~1/8 inch
- A jewel-tone color range
- Pieces small enough to conform to the globe's curve
