care principles
Care principles

Prevention

Damage is irreversible.

Create a dark, cool, clean, dry

and stable environment

care principles1
Care principles

Prevention

Damage is irreversible, create a stable environment

Purpose – what are we trying to achieve?

Mission policy, display, reference, hands on, accommodate artist’s intent?

Continuity - establish good practice

Maximise access, minimise handling

Any plan is better than none

prioritise the problem plastics
Prioritise the problem plastics

Identify:

Cellulose acetate

Cellulose nitrate (celluloid)

Plasticised PVC

Polyurethane polyester foams

Isolate

Ventilate

Monitor

signs of deterioration
Signs of Deterioration

Odour – acidic, camphor (CN)

Change: colour -yellowing, bleaching shape –distortion, sagging, sweating – oily spots bloom – white powder cracks, splits (CAc) and crazing(CN)

Corrosion of metal parts

Discolouration of packing materials

Increased brittleness, crumbling of foam

Onset is unpredictable and rapid

Occurs at stress points and handled areas

Unstable environments cause stress

causes of deterioration
Causes of deterioration

Inherent vice –material, manufacture, history, shape, stress

causes of deterioration1
Causes of deterioration

Inherent vice –material, manufacture, history, shape, stress

Unstable environment -excess light, temperature swings, changes in relative humidity, pollutants

causes of deterioration2
Causes of deterioration

Inherent vice –material, manufacture, history, shape, stress

Unstable environment -excess light, temperature swings, changes in relative humidity, pollutants

Mechanical damage – handling, transport & housekeeping. Wear gloves

Cleaning and misconceived repairs

light damage
Light damage

Cumulative and irreversible

Affects both the plastic and pigments

Control light in storage and on display

UV component in light is most damaging

Use UV filters on windows and lights

storage
Storage

Stable conditions at all times

Clean & dry

Cool & dark

Minimise handling

labels

storage1
Storage

Use: ‘archival’ quality material

Avoid contact with wood, metals, dust and other ‘objects’

Acid free paper

Silicone release paper

Polyester wadding

Polypropylene containers

Plastazote (closed cell polyethylene foams)

storage problem plastics
Storage – Problem Plastics

Isolate and separate ‘at risk’ from ‘deteriorating’ objects

Use:

Acid free paper

Silicone release paper

Polyester wadding

Ventilated polypropylene containers

Scavengers for acidic gases

Charcoal cloth and zeolites

Artsorb board

storage problem plastics1
Storage – Problem Plastics

Check vulnerable ‘at risk’ items at least once a year, preferably more often.

Use smell and dampened indicator strip to confirm acidic off-gassing.

display problem plastics
Display –Problem Plastics
  • Low light - less than 100 lux
  • Ventilated plinth covers
  • Allow at least 72 hours for plinth paint to dry before covering
labelling
Labelling

Avoid solvent based inks, paints and isolating layers.

Avoid adhesive tapes

Avoid rubber bands

Use tie on labels with cotton tape

Use soft pencil (inside objects)

cleaning
Cleaning

To remove dust and contaminants

Cleaning causes damage – both mechanical and chemical

Decide on a balance between appearance and risk of damage

Avoid solvents, eg alcohols, acetone, cellulose thinners, cleaning fluids

Use soft dry lint free cloths, eg microfibre

For stubborn marks only, use water to dampen cloth and dry immediately

other plastic formats
Other plastic formats

Fabrics – costumes and accessories - provide supports, isolate PVC’s

Photograhic – archival quality storage materials

New media: videos, tapes, disks – a management policy is essential for maintenance and migration.
