Question

a) Discuss in detail the preservation of materials, causes of deterioration of materials in a warehouse and explain how the following common materials are preserved (show the sketches where required) o Paints o Rubber and Rubber Products o Fragile items.

Answer 1

Proper content management contributes directly to balance sheet gain. The restoration techniques take care of the relevant aspects:

• Economic Aspects — The expense of the restoration effort and the money saved by such measures can be compared to the cost of not making any restoration effort. When the damages involved in the restoration campaign are as much as the expense of the item itself is procured, it is not Wahhabi to go with the endeavor.
• Part Idleness Duration-Long-term methods may vary from short-term methods.
• Spare Part or Material Condition-Whether the item is not intended to last long or has eroded so badly that restoration only has a slight impact, it might not be worth the effort to save it.
• Viability of the Preserving Method-If a preserving method provides a small increase in the life of a commodity, it may not be worthwhile because of the costs involved with the procedure.

A separate "Preserving Book" is also ideal, and is open to those involved within an organization. This Handbook will be as detailed as possible.

Agents of Deterioration:

• Physical forces: Examples of dangerous physical forces can include those that are sudden and devastating, including both natural catastrophe and operator error (such as earthquakes, or bumping or falling an object), or slower behaving with small yet frequent opportunities for damage (such as inadequate handling during testing and educational usage, or vibrations from nearby construction).
• Thieves, Looters, Displacers: It covers, Planned robbery by those intending to damage the set, unscrupulous tourist fraud, staff maltreatment, and arson.
• Fire: Fire will theoretically result in the sudden and devastating destruction of a whole array.
• Water: Water collections storage areas are often located in attic or basement spaces that are more vulnerable to water loss in the case of a roof or plumbing failure, breakdown of the sprinkler system or flood.
• Pests: The plagues contain both mice and insects. Mold / mildew / fungi is often considered by others to be into this umbrella.
• Pollutants: Pollutants can be produced in buildings, both outside and within. Many chemicals considered to cause problems in human health can also pose damage to collections. Particulates and gasses are the two general types of pollutants which contribute to the deterioration of museum collections. These may be moved by close communication or airborne.
• Light: Radiation damage (visible, ultraviolet or infrared), which is continuous and, if incurred, permanent, is a property of luminous intensity (in lux or footcandles) times the exposure duration.
• Incorrect Temperature: The adverse effects of inappropriate temperature (either too high or too low) are always observed after a significant amount of time has passed, thereby underestimating the gradual degradation which occurs.
• Incorrect Relative Humidity: Natural products all contain moisture; they absorb and release moisture, and seek to strike a balance between their humidity and that in the air surrounding them. If the humidity (moisture content) in the air goes up, moisture and swell will be absorbed, and if it goes down they will give off humidity and shrink. If this occurs slowly and gradually then it does not do any harm. Nevertheless, abrupt, significant and regular changes in relative humidity can cause the objects made of organic materials to shrink, warp, break, and gradually age. A sudden rise in relative humidity will cause metal objects to condense, which will encourage corrosion.
• Custodial Negligence & Dissociation: Another instance of custodial negligence happens where diligent action is not taken to protect the collection, or where the collection records and procedures are not up to date. The second form of custodial negligence is that collection items are disassociated from their data.
