Conservation, Presentation and Care of Artworks - Unit 4 AM&E

Environmental considerations and conservation fundamentals

• Purpose: Understand methods for presentation, conservation, and care of artworks during display, storage, handling, and transportation.

• Key focus areas: Environmental factors (lighting, temperature, humidity), handling/transport, condition reporting, material stability, and ethical considerations (cultural protocols, artist’s intention vs. public access).

Presentation of artworks

• Involves lighting, spatial qualities, surface treatments, and placement to communicate ideas and influence viewer interaction.

Production & presentation of artworks: roles and processes

• Production pathway: Artist's intention guides display.

• Gallery context: Roles include curation, exhibition design, conservation, and promotion.

Types of conservation

• Preventative: Long-term stability, impeding deterioration (e.g., environmental control, handling).

• Remedial (corrective): Halting/reversing deterioration and damage effects.

Core areas of conservation for artworks

• Lighting, Temperature, Storage, Transportation, Presentation critical for protection and longevity.

Lighting, visibility, and exposure to light

• Light sensitivity varies by material (e.g., high for photos/paper, low for ceramics/stone).

• Exposure guidelines: Manage lux and duration to prevent fade. Higher lux accelerates deterioration, as illustrated by examples for Just Noticeable Fade (JNF):

  • $50\,\text{lux} \rightarrow 50\,\text{days/year}$

  • $150\,\text{lux} \rightarrow 166\,\text{days/year}$

  • $250\,\text{lux} \rightarrow 365\,\text{days/year (unlimited)}$

Temperature and relative humidity (RH)

• Ideal climate: $20^{\circ}\text{C} - 24^{\circ}\text{C}$ with RH $50\% \pm 5\%$

• Fluctuations: Cause expansion/contraction, accelerating deterioration.

• Monitoring: Climate-control systems and data loggers maintain stability (e.g., NGV: RH $40\% - 60\%$, Temp $15^{\circ}\text{C} - 25^{\circ}\text{C}$).

Environmental monitoring

• Key variables: RH and Temperature.

• Target guidelines: $\Delta T\le 4^{\circ}\text{C}$ per 24 hours, $\Delta \text{RH}\le 10\%$ per 24 hours.

Vermin and pest management

• Essential controls: cleaning, food/drink bans, electronic repellents, trapping systems to prevent damage to organic materials.

Security and access control

• Protects artworks from theft, vandalism, and accidental damage.

Storage

• Protect from light, pests, dust, physical damage.

• Solander Box: pH neutral, light-safe, bug-safe, airtight for secure storage.

Handling guidance

• Plan routes, avoid touching faces of 2D works, use gloves (cotton, latex, nitrile), avoid moving flaking paint, remove jewelry, use two hands/people if needed, avoid finger insertion for canvases without backing boards.

Transportation and shipping

• Risks: Increased damage from environmental fluctuations and handling.

• Packing: Avoid bubble wrap/other problematic materials directly on artwork; use re-usable, chemically inert materials.

• Pre-shipping checks: Do not ship artworks with flaking paint; use protective backing for fabric supports; tape glass for framed works; remove dust.

• Recommended materials: Tyvek (long-term storage/interleaf), Mylar (interleaf), Silicone-release Mylar (direct contact).

• Cushioning: Polyethylene foam (Ethafoam/Volara) recommended; Polyurethane foam for short-term with interleaf barrier.

Condition reports and documentation

• Document artwork state pre/post conservation and track changes over time.

Practical implications and professional considerations

• Ethical responsibilities (Indigenous artworks), balancing artist’s intent with access, adaptable strategies for site-specific art, and prioritizing inert, non-acidic storage/packing materials.

Summary of key numerical references

• Temperature: $20^{\circ}\text{C} \le T \le 24^{\circ}\text{C}$, change limit $|\Delta T| \le 4^{\circ}\text{C} \text{ per 24 hours}$.

• Relative humidity: $40\% \le \text{RH} \le 60\%$ or target $\text{RH} = 50\% \pm 5\%$.
