Museum Display Cases Artifacts Damage Reasons: Causes & Solutions

Why Are Artifacts Damaged in Museum Display Cases? Causes and Preventive Conservation Solutions

Museum display cases are designed to protect valuable objects while allowing visitors to appreciate their historical and cultural significance. However, placing an artifact inside a case does not automatically guarantee its long-term preservation. Fluctuating humidity, excessive light, harmful chemical emissions and physical risks can still contribute to deterioration.

Understanding the main museum display cases artifacts damage reasons is an important step toward better exhibition planning. Through preventive conservation, museums can reduce avoidable risks by selecting appropriate case materials, managing the internal environment and establishing regular monitoring procedures.

1. Four Common Causes of Artifact Damage

1.1 Humidity and Temperature Fluctuations

Changes in relative humidity can cause organic materials such as wood, paper, textiles and leather to expand or contract. Repeated fluctuations may contribute to cracking, warping, deformation or weakened structures. Metals may also corrode under unsuitable environmental conditions, especially when moisture and pollutants are present.

Temperature changes can affect relative humidity and accelerate certain deterioration processes. A display case with suitable sealing and microclimate control can help buffer artifacts against rapid changes in the surrounding gallery.

The appropriate temperature and humidity range depends on the materials, condition and conservation history of each object. Museums should establish environmental targets with qualified conservators rather than apply one setting to every collection.

1.2 Excessive Light and Ultraviolet Exposure

Light damage can cause fading, discoloration and chemical changes in sensitive materials, including textiles, paper, photographs and painted surfaces. Ultraviolet radiation can contribute to deterioration, while heat generated by some lighting arrangements may create additional environmental stress.

Preventive measures include using low-UV lighting, installing suitable UV-filtering glazing where appropriate, Light-sensitive artifacts may require lower light levels, shorter display periods or rotation with objects kept in dark storage.

UV-filtering glass is useful, but it does not eliminate all light-related risks. Visible light can also cause cumulative damage, so lighting intensity and exposure duration must be considered together.

1.3 Harmful Emissions Released by Display Case Materials

A display case can become a source of risk if its construction materials release harmful gases or volatile compounds. Certain woods, composite boards, paints, adhesives, sealants and fabrics may emit substances that accumulate inside an enclosed case.

These emissions can contribute to corrosion, discoloration or other chemical changes, depending on the pollutants and the objects displayed. The risk is particularly important when sensitive artifacts are placed in a poorly assessed microenvironment.

For preventive conservation, display case materials should be selected for chemical stability and compatibility with the collection. Where appropriate, materials can be evaluated through recognized testing procedures, such as the Oddy test. New cases should also be allowed to off-gas in a suitable, well-ventilated area before installation of sensitive objects, following professional conservation advice.

1.4 Vibration, Handling and Physical Contact

Artifacts may suffer damage during transportation, installation, maintenance or accidental contact. Vibrations caused by nearby equipment, building activities or visitor movement may also pose risks to fragile objects. The potential impact depends on each artifact’s condition and the intensity of the vibration.

A well-designed case should provide stable support, secure mounting and appropriate access for authorized staff. Reliable locks, carefully designed opening mechanisms and suitable object supports can reduce handling risks. Routine inspections also help identify loose fittings, damaged seals and other issues before they become more serious.

2. How to Prevent Artifact Damage with Better Display Cases

2.1 Display Case Materials: Types and Selection Criteria

The materials used in a museum display case affect its strength, visibility, chemical stability and ability to support preventive conservation.

Common materials include:

Glass: Provides clear viewing and a durable barrier. Low-reflection or UV-filtering options may be appropriate depending on visibility and conservation requirements.
Metal: Often used for structural frames because it can provide strength and dimensional stability when properly finished and protected against corrosion.
Acrylic and other plastics: Can offer lightweight or specialized design options, but their optical properties, scratch resistance, cleaning requirements and long-term suitability should be assessed for each application.
Sealants, adhesives, coatings and interior finishes: These must be chosen carefully because some formulations may release compounds that are harmful to collection materials.
Supports and interior fittings: Should be stable, appropriate for the artifact and compatible with its material and condition.

The best material combination depends on the objects being displayed, the case design and the required conservation performance. A qualified case manufacturer should work with the museum team to confirm material suitability rather than rely on appearance alone.

2.2 Use Microclimate Control Where Needed

Microclimate control helps manage the conditions inside a display case independently of the wider gallery environment. Depending on the collection and project requirements, this may involve passive humidity buffering, a suitable humidity-control system, environmental sensors or integrated temperature and humidity monitoring.

A well-sealed case can help reduce rapid environmental fluctuations, but the result depends on its construction, leakage rate, internal materials and maintenance. Active control equipment also requires suitable installation, monitoring and servicing.

For sensitive collections, museums should define target conditions with conservation professionals and verify actual performance after installation.

2.3 Select Suitable UV-Filtering Glazing and Lighting

Glazing and lighting should be planned together during exhibition design. UV-filtering glass can reduce ultraviolet transmission, while low-UV light sources, adjustable illumination and carefully managed exposure periods can further reduce the risk of light-related damage.

Low-reflection glass may also improve visibility by reducing distracting reflections. However, reflection control and UV protection are different properties. Museums should confirm the specifications of the selected glazing instead of assuming that every low-reflection product provides the same UV performance.

Lighting design should also avoid unnecessary heat near sensitive objects and allow staff to adjust illumination to the needs of each collection.

2.4 Combine Security, Monitoring and Maintenance

Preventive conservation is an ongoing process, not a one-time product choice. Display cases should be designed to support secure access, safe installation, routine inspection and maintenance.

Depending on project requirements, useful features may include secure locks, alarms, reliable seals, accessible environmental monitoring and service compartments for humidity-control materials or equipment.

After installation, museum staff should check environmental readings, glazing condition, seals, locks and internal fittings at appropriate intervals. Any change in the artifact’s condition should be reviewed by qualified conservation personnel.

3. Choosing Preventive Conservation Display Cases for Your Collection

When selecting preventive conservation display cases, museums should begin with the collection rather than a standard cabinet specification. Paper, textiles, archaeological metals, ceramics and mixed-material objects can have different environmental and display requirements.

Before finalizing a design, consider the following questions:

What materials are the artifacts made of, and what is their current condition?
Are humidity buffering or active environmental controls required?
What level of light exposure is appropriate for the collection?
Have the structural materials, coatings, adhesives and sealants been assessed for compatibility?
How will staff access, clean, inspect and maintain the case?
What security, monitoring and installation requirements must the project meet?

For museums planning new galleries or upgrading existing exhibitions, a customized case can bring these requirements together in a practical design. The final specification should be reviewed with the museum’s conservation team, especially when displaying fragile or chemically sensitive objects.
