However, today the definition of the role of conservation has widened and would more accurately be described as that of ethical stewardship
Stewardship
Stewardship is an ethic that embodies responsible planning and management of resources. The concept of stewardship has been applied in diverse realms, including with respect to environment, economics, health, property, information, and religion, and is linked to the concept of sustainability...

.

The conservator applies some simple ethical guidelines, such as:
  • Minimal intervention.
  • Appropriate materials and methods that aim to be reversible to reduce possible problems with future treatment, investigation, and use.
  • Full documentation of all work undertaken.


In order for the conservator to apply their professional expertise accordingly, they must take into account the views of the stakeholder, the values
Values (heritage)
The values embodied in cultural heritage are identified in order to assess significance, prioritize resources, and inform conservation decision-making...

Brief history


The care for cultural patrimony has a long history within traditions of fixing and mending objects, and in individual restorations of artworks. During the 19th century, the fields of science and art became increasingly intertwined as scientists such as Michael Faraday began to study the damaging effects of the environment to works of art. Louis Pasteur carried out scientific analysis on paint during this time period as well. However, perhaps the first organised attempt to conserve cultural patrimony was the Society for the Protection of Ancient Buildings
Society for the Protection of Ancient Buildings

He not only developed a scientific approach to the care of objects in the collections, but disseminated this approach publishing a "Handbook of Conservation" in 1898. The early development of conservation in any area of the world is usually linked to the creation of positions for chemists within museums. However in the United Kingdom, pioneering research into painting materials and conservation, ceramics, and stone conservation was conducted by Arthur Pillans Laurie, academic chemist and Principal of Heriot Watt University from 1900.

The rapid growth of conservation professional organizations, publications, journals, newsletters, both internationally and in localities, has spearheaded the development of the conservation profession, both practically and theoretically. Art historians and theorists such as Cesare Brandi

Most significantly has been the idea of Preventive conservation. This concept is based in part on the pioneering work by Garry Thomson

, and his book the Museum Environment, first published in 1978. Thomson was associated with the National Gallery (London), it was here that he established a set of guidelines or environmental controls for the best conditions in which objects could be stored and displayed within the Museum Environment. Although his exact guidelines are no longer rigidly followed they did inspire this field of conservation.

Ethics


The conservator's work is guided by ethical standards. These take the form of applied ethics
Applied ethics
Applied ethics is, in the words of Brenda Almond, co-founder of the Society for Applied Philosophy, "the philosophical examination, from a moral standpoint, of particular issues in private and public life that are matters of moral judgment"...

. Ethical standards have been established across the world, and national and international ethical guidelines have been written. One such example is:


Conservation OnLine's Ethical issues in conservation provides a number of articles on ethical issues in conservation; example of codes of ethics and guidelines for professional conduct in conservation and allied fields; and charters and treaties pertaining to ethical issues involving the preservation of cultural property.

 light. They must be protected in a controlled environment where such variables are maintained within a range of damage-limiting levels. Shielding from sunlight of artifacts such as watercolour paintings for example is usually necessary to prevent fading of pigments.

Preventive conservation is an important element of museum policy and collections care. It is an essential responsibility of members of the museum profession to create and maintain a protective environment for the collections in their care, whether in store, on display, or in transit. A museum should carefully monitor the condition of collections to determine when an artifact requires conservation work and the services of a qualified conservator.


Interventive conservation



Interventive Conservation refers to any act by a conservator that involves a direct interaction between the conservator and the cultural material. These interventive treatments could involve cleaning, stabilizing, repair, or even replacement of parts of the original object. It is essential that the conservator should fully justify any such work. Complete documentation of the work; carried out before, during, and after the treatment rules out chances of later doubts.

The principal goal of a conservator is to nullify or at least reduce the rate of deterioration of an object, this can be achieved through either non-interventive or interventive methodologies. Interventive methodologies include all those actions taken by the conservator to directly intervene with the material fabric of the object. Such actions include surface cleaning such as varnish removal, or consolidation such as securing flaking paint. Such interventive actions are carried out for a variety of reasons including; aesthetic choices, Stabilization needs for structural integrity, or for cultural requirements for intangible continuity.

One of the guiding principles of conservation has traditionally been the idea of reversibility, that is that all interventions with the object should be fully reversible, and the object should be able to be returned to the state in which it was prior to the conservators intervention. Although this concept remains a guiding principle of the profession, it is a concept that has been widely critiqued within the conservation profession and is now considered by many to be "a fuzzy concept". Another important principle of conservation is that all alterations should be well documented and should be clearly distinguishable from the original object.

An example of a highly publicized interventive conservation effort would be the conservation work conducted on the Sistine Chapel
Restoration of the Sistine Chapel frescoes

The results of this work was the report A Public Trust at Risk: The Heritage Health Index Report on the State of America's Collections, which was published in December 2005 and concluded that immediate action is needed to prevent the loss of 190 million artifacts that are in need of conservation treatment. The report made four recommendations:
  • Institutions must give priority to providing safe conditions for the collections they hold in trust.
  • Every collecting institution must develop an emergency plan to protect its collections and train staff to carry it out.
  • Every institution must assign responsibility for caring for collections to members of its staff.
  • Individuals at all levels of government and in the private sector must assume responsibility for providing the support that will allow these collections to survive

, a governmental department, authored a document: "Understanding the Future: Priorities for England's Museums". This document was based on several years of consultation aimed to lay out the government's priorities for museums in the 21st century.

The document listed the following as priorities for the next decade:
  1. Museums will fulfil their potential as learning resources (pp 7–10).
    • Museums will be embedded into the delivery of education in every school in the country.
    • Understanding of the effectiveness of museum education will be improved further and best practice built into education programmes.
    • The value of museums' collections as a research resource will be well understood and better links built between the academic community and museums.
  2. Museums will embrace their role in fostering, exploring, celebrating and questioning the identities of diverse communities (pp 11–14).
    • The sector needs to work with partners in academia and beyond to create an intellectual framework supporting museums' capacity to tackle issues of identity.
    • The museum sector must continue to develop improved practical techniques for engaging communities of all sorts.
  3. Museums' collections will be more dynamic and better used (pp 15–18).
    • Government and the sector will find new ways to encourage museums to collect actively and strategically, especially the record of contemporary society.
    • The sector will develop new collaborative approaches to sharing and developing collections and related expertise.
  4. Museums' workforces will be dynamic, highly skilled and representative (pp 17–22).
    • Museums' governing bodies and workforces will be representative of the communities they serve.
    • Find more varied ways for a broader range of skills to come into museums.
    • Improve continuing professional development.
  5. Museums will work more closely with each other and partners outside the sector (pp 23–26).
    • A consistent evidence base of the contribution of all kinds of museums to the full range of public service agendas will be developed.
    • There will be deeper and longer lasting partnerships between the national museums and a broader range of regional partners.
    • Museums' international roles will be strengthened to improve museum programmes in this country and Britain's image, reputation and relationships abroad.

Concluding:

Further to this the ICON website summary report lists the following specific recommendations:
  • A national survey to find out what the public want from museums, what motivates them to visit them and what makes for a rewarding visit.
  • A review of survey results and prioritisation of the various intrinsic, instrumental and institutional values to provide a clear basis for a 10-year strategy
  • HR consultants to be brought in from the commercial sector to review recruitment, career development and working practices in the national and regional museums.
  • A commitment to examine the potential for using Museum Accreditation as a more effective driver for improving recruitment, diversity, and career development across the sector.
  • DCMS to take full account of the eventual findings of the current Commons Select Committee enquiry into Care of Collections in the final version of this document
  • The adoption of those recommendations of the recent House of Lords enquiry into Science and Heritage which have a potential impact on the future of museums.

, whereby an apprentice slowly developed the necessary skills to undertake their job. For some specializations within conservation this is still the case. However, it is more common in the field of conservation today that the training required to become a practicing conservator comes from a recognized university course in conservation.

The University can rarely provide all the necessary training in first hand experience that an apprenticeship can, and therefore in addition to graduate level training the profession also tends towards encouraging conservation students to spend time as an intern

Art selection


Due to the large quantities of artwork in modern times, there have debates as to whether all art is actually worth preserving.

Associations and professional organizations



Societies devoted to the care of cultural heritage have been in existence around the world for many years. One early example is the founding in 1877 of the Society for the Protection of Ancient Buildings
Society for the Protection of Ancient Buildings

The built heritage was also at the forefront of the growth of member based organizations in the United States
United States

 for example, founded in 1889, the Richmond, Virginia-based Preservation Virginia (formerly known as the Association for the Preservation of Virginia Antiquities) was the United States' first statewide historic preservation group. In 2003, it changed its name to reflect its wider focus in statewide preservation issues.

Today, professional conservators join and take part in the activities of numerous conservation associations and professional organizations with the wider conservation field, and within their area of specialization.

These organizations exist to "support the conservation professionals who preserve our cultural heritage".

This involves upholding professional standards, promoting research and publications, providing educational opportunities, and fostering the exchange of knowledge among conservators, allied professionals, and the public.
