Q

Natural fibres and man made fibres

What are the effects of heat & fire residues for textiles? (2)

A
  1. NATURAL FIBRES: Less sensitive to low heat, release odours & residues more freely.
  2. MAN MADE FIBRES: Soften & distort at low temps, become polarised, retain residues & odours and are liable to discolouration and staining.

Q

What are the effects of heat & fire residues for ceramics? (2)

A
  • If fired at high temp & well glazed. ceramics are somewhere imperial to heat damage & do not absorb residues
  • If unglazed or fired at low temp they are more porous, absorbing fire residues more easily.

Q

What restoration techniques would you use for kitchenware? (2)

A
  1. Usually robust, responds well to cleaning. Low value, doesn’t justify extensive works.

17
Q

What restoration techniques would you use for kitchenware? (1)

A
  1. Ultrasonics and/or washing with a range of alkaline and degreasing solutions.
18
Q

What are the effects of heat & fire residues for documents & books?(6)

A
  1. Usually visible on spines & covers
  2. Higher the shelve, more damage.
  3. Embrittled paper, not reversible
  4. Loose residues can often be removed but absorbed residues may be permanent
  5. If appearance not issue, can be cleaned to remove residues, deodorised and returned to use
  6. Glossy coated paper much more likely to be damaged as softens and pages stick together
19
Q

What restoration techniques would you use for documents & books?(Packing out, pages & covers)

A
  1. Packing out;

    - Absorbent material - dry sponge
    Glossy - consider careful damp wipe cleaning
    Leather - consider using appropriate specialist cleaner
20
Q

What restoration techniques would you use for recorded media?(CD&DVDS/AUDIA/VIDEO TAPES/ VINYL RECORDS)

A
  1. CDS/DVDS;
