Which defect is most serious for cherry veneer quality?

• A. Gum spots, which disfigure the veneer and affect finishes.
• B. Pin knots that do not affect finish.
• C. Mineral streaks that have no effect on finish.
• D. Blue stain that dulls the color.

Answer: (A)

When evaluating cherry veneer quality, how the surface looks and how evenly it accepts finish are the main concerns. Gum spots are the most serious because they create resin pockets that disfigure the surface and cause finishes to absorb unevenly. This leads to blotching and an inconsistent appearance that is hard to hide with sanding or filler, and it typically lowers the veneer’s grade. Pin knots are small, localized defects that often don’t affect the finish and can be trimmed or filled without ruining the overall appearance. Mineral streaks are cosmetic color variations that usually don’t impact the finish or structural performance. Blue stain changes the color tone, dulling the appearance, but it doesn’t cause the same level of surface irregularity or finish adhesion problems as gum spots.
