Preserving bone specimens involves careful cleaning, stabilization, and storage to prevent damage and degradation. This ensures the long-term integrity of the specimen for research, education, or display.
Cleaning the Bone Specimen
Before storage, thoroughly clean the bone to remove any remaining soft tissue. This might involve methods like dermestid beetle cleaning (using beetles to consume soft tissue) or enzymatic maceration. Proper cleaning prevents further decomposition and potential pest infestation.
Stabilizing the Bone Specimen
Once clean, the bone may benefit from stabilization. This process helps prevent further deterioration. While techniques vary depending on the bone's condition, this might include treatments to solidify the bone structure and reduce its fragility.
Storing the Bone Specimen
Proper storage is crucial for long-term preservation.
Storage Containers and Materials
- Containers: Use sturdy boxes or trays to house the specimens.
- Padding: Closed-cell polyethylene foam is ideal for cavity-packing and padding, protecting the bone from damage during handling and storage. For larger specimens, custom foam-lined cradles might be necessary. This prevents breakage and movement within the container.
Environmental Considerations
- Temperature and Humidity: Maintain a stable temperature and humidity to minimize environmental degradation. Fluctuations can cause cracking and warping.
- Pest Control: Regularly inspect for insect infestations. Proper cleaning and storage help mitigate this risk.
Example: Storing a Skull
A cleaned skull would be carefully placed in a box lined with closed-cell polyethylene foam. The foam would be shaped to support the skull, preventing movement and potential breakage. The box should be sealed to protect against dust and pests.
