Conservation Flashcards
Two types of materials
Organic and inorganic
Types of organic materials
Paper
Wool
Leather
Feathers
Types of inorganic materials
Metals
Stone
Cement
Ceramic
Factors of conservation
Preservation
Protect + prevent
Keeping work in original condition for as long as possible
How do they achieve safe handling and checking?
Security
Paying attention to light levels
Using nitrile gloves
Adequate viewing between works
What causes damage?
Incorrect handling
Poor storage
Dust accumulation
Light, temp, relative humidity
What happens with inadequate light levels?
Works become embrittled
Paper discolours
Colour fades
Lux for ceramics, stone, and glass?
300 Lux
Lux for textiles and paper?
50 Lux
Lux for oil paintings and wooden objects?
150-250 Lux
What is the equation for temperature and RH?
20c +/- 2c, 50% RH +/- 5%
What happens with inadequate light, temp, and relative humidity?
Cracking + tears
Expansion or contraction
Mould, bacteria, fungi, insects
What is mould?
Fungi that lives on any organic material, feeding off organic matter.
When does mould grow?
Foxxing occurs when RH is over 70%.
What does foxing cause?
Physical breakdown of work (eg. paper becomes soft and spongey, making it liable for disintegration.)
Damage is irreversible.
Pollutants and dust examples
Atmospheric pollutants (eg. CO2, dust, soot, ozone).
What effect does pollutants have on metal?
Corrosion
What effect does pollutants have on stone?
Acid damage
What effect does pollutants have on paper?
Staining and soiling
What effect does pollutants have on textiles?
Physical breakdown
Preventative measure for dust nd pollutants?
Display cases
What do insects do to works?
Feed on organic materials, photographs, and textiles.
Insect droppings stain works.
How do they eradicate insects?
Can put insects in bag and remove oxygen.
What do pests do to works?
Gnawing and soiling.
