year 12 Flashcards
conservation
the preservation of artworks. protect and prevent damage to artwork and keep artwork to its original state to as much as possible
preventing damage- environmental factors
that contibute
orgainic materials
paper, leather, wool, feathers
inorganic material
stone, cement, ceramic, metals
public gallery conservation
large galleries follow international conservation guidelines and employ teams to ensure these standards are meet
commercial gallery conservation
ari conservation
handling and checking
using gloves, creating adequate veiwing spaces, paying attention tolight levels, keep storage and display areas clear of dust and toxic materials , being aware of security issues. during and exhibiton the curator will check works regularly for movement, damage, dust and any changes to the work, regularly checking
lighting
lighting is a major contributor to the deteriration of materials used in making works of art as it causes colours to fade
minisming light damage
-elimataing direct sunlight
- amximising UV light, which is not required for the vewiing of works of art
-reducing exposure to light, by roatating objects between
temperature and relitive humidity
temperature and relative humdidity (RH) are diectly related to each other
changes in temperature and RH can cause
-expansion and contraction of particular materials, resulting in increases in cleavage (the separation of layered structures), cracking and tears
-mould , bacteria and fungi growth in RH i high and insect attack
-chemical recations that result in chemicak breakdown of materials (eg. dicoloeration and embrittlement of paper)
-cracking an flaking of emulsion layer
-high temps- accelerate the chemical
preventative measure
-maintain air-conditioning levels (usually 20 degrees)
-maintain RH levels (usually 50%) - use thermohygrometer , dehumidifers, humidifers
-preventing direct sunlight
-elimate cold draghts and cold air
-enclosing artworks in play acse (reduced humidity fluctuation)
