Great collections are built over years, but they're destroyed in months by improper storage. Conservation is not optional—it's the difference between a growing investment and a depreciating one. Here's the definitive care guide.
Climate Control: The Foundation
Temperature: 60–70°F (15–21°C). Temperature fluctuation causes expansion and contraction that cracks paint and warps paper. Avoid basements (cold and damp) and attics (hot and dry).
Humidity: 45–55% RH. Too high = mold and foxing. Too low = cracking and brittleness. A digital hygrometer ($20) and a portable humidifier/dehumidifier can maintain optimal conditions in most spaces.
Light: The Silent Destroyer
UV light fades pigments irreversibly and at a faster rate than most collectors expect. Even "indirect" natural light causes cumulative damage. Rules:
- Never display works in direct sunlight—ever
- Use UV-filtering museum glass or acrylic for all framed works
- Use LED lighting for display (LEDs emit minimal UV and generate less heat than incandescent)
- For unframed stored works, archival storage boxes block light completely
Storage Materials
- Prints and works on paper: Flat archival boxes with acid-free interleaving tissue between each work
- Rolled works: Acid-free tissue around the work, then rolled around an archival tube (never PVC)
- Canvases: Stored upright, never stacked flat (weight causes deformation)
- Sculptures and figures: Original packaging preferred; archival foam if original box unavailable
Insurance
Fine art insurance is separate from homeowners insurance and requires a professional appraisal. Budget 1–2% of collection value annually. Works above $5,000 should have individual scheduled coverage.
