The design of display cases and protective coverings plays a crucial role in effectively showcasing artifacts while ensuring their preservation. Here are some detailed considerations:
1. Material Selection: Display cases and coverings should be made from materials that are chemically stable and non-reactive with the artifact. Common materials include acrylic, glass, and certain types of plastics, which are optically clear and provide the necessary protection against harmful elements like UV radiation, dust, and moisture.
2. UV Protection: Artifacts are often susceptible to damage from exposure to ultraviolet (UV) radiation, which can cause fading, discoloration, and deterioration. Display cases must incorporate UV-protective technologies like UV-filtering glazing or coatings to minimize the transmission of harmful UV light while maintaining visibility.
3. Climate Control: Proper environmental conditions are critical for artifact preservation. Display cases should include a climate control system to regulate temperature, humidity, and airflow. Temperature should be kept stable, typically between 18-22 degrees Celsius (64-72 degrees Fahrenheit), while relative humidity levels should ideally range between 40-55%. Airflow control can help minimize the accumulation of dust and pollutants.
4. Sealing and Gaskets: Display cases need to be sealed against external elements like dust, moisture, and pests. High-quality gaskets or seals are incorporated around doors, windows, and any other openings to ensure a tight seal, preventing unwanted infiltration.
5. Lighting: Illumination is crucial for effective artifact display, but it must be carefully designed to minimize the artifacts' exposure to excessive light and heat. Lighting should be low in UV emission and heat generation. LEDs are often preferred due to their ability to generate minimal heat and offer precise control over intensity, color, and direction.
6. Mounting and Supports: Artifacts should be properly mounted or supported within the display case to prevent movement, vibration, or damage. Customized mounts, cradles, or supports made from chemically inert materials should be designed to securely hold the artifact without causing stress or pressure points.
7. Accessibility and Security: Display cases should enable easy access for maintenance, cleaning, and artifact handling, while also providing security to prevent unauthorized access or theft. This may involve incorporating features like lockable doors, security alarms, security cameras, and restricted access controls.
8. Display Considerations: Designing the interior of the display case is equally important. Attention should be given to the arrangement, lighting angles, and layout to highlight the artifact's key features, textures, and details. The overall presentation should be aesthetically pleasing and informative to engage visitors.
Ultimately, the design of display cases and protective coverings should balance the need for artifact visibility and access with ensuring their long-term preservation and protection from potential deterioration or damage. Collaborating with conservation specialists and museum professionals can help ensure that the design meets the specific requirements of the artifact and the exhibition space.
