The short answer
The most common beginner mistakes are: cutting pieces too large for the curve, using cloudy or rigid glue, mixing grout too runny, skipping cure time, leaving gaps uneven, forgetting eye protection, and rushing the wipe-down. Each is easy to avoid once you know it.
The 7 mistakes
- Pieces too big for the globe. Large flat pieces lift off a curve — keep them ½–1 inch.
- The wrong glue. Cloudy or rigid glue dulls the glow or cracks with heat — use a clear, flexible adhesive.
- Runny grout. Too much water = weak, crumbly joints. Mix to a thick paste.
- Skipping cure time. Grouting before the glue dries shifts your design. Wait ~12 hours.
- Uneven gaps. Wildly different gaps look messy once grouted — aim for consistent spacing.
- No eye protection. Cutting glass throws shards — glasses and cut-resistant gloves are non-negotiable.
- Rushing the wipe-down. Wipe grout off the glass before it fully hardens, or you'll fight a haze later.
