Complete guide for specimen storage setup — step-by-step workflow, tools, checklist, and expert tips to get started.
Assign drawers for micromounts, shoebox trays for thumbnails, and padded shelves for fist-sized specimens.
Line drawers with ethafoam; build cardboard cell dividers for thumbnail specimens; use egg cartons for temporary field storage.
Target 40–50% RH and stable 65–70°F; recharge silica gel canisters monthly in oven at 250°F for 2 hours.
Label every drawer and cell with location code matching catalog; audit physical vs catalog inventory quarterly.
Map storage location codes to catalog entries and track quarterly inventory audit results.
Monitor storage relative humidity targets and calculate silica gel recharge schedule.
Estimate specimen weight for shelf load planning and heavy specimen lower-shelf placement.
Schedule quarterly inventory audits and silica gel recharge dates from last maintenance.
Recommended conditions for mineral specimen preservation.
| Parameter | Target | Risk |
|---|---|---|
| Temperature | 65–70°F | Thermal cycling cracks crystals |
| Relative humidity | 40–50% RH | Pyrite disease above 60% |
| Light | Dark storage | Amethyst fades in weeks |
| Pyrite zone | < 40% RH | Sulfuric acid formation |
Contact between specimens causes permanent crystal damage — individual cells always.
Pyrite in humid storage produces sulfuric acid — check sulfides monthly for white powder.
Basement flood destroys decades of collection in minutes — minimum 6 inches off floor.
