Conservation principles and methods

Conservation Principles

Understand the ethics of metalwork conservation, focusing on preserving original material and features.
Grasp the key concept of minimum intervention, i.e., undertaking the least possible amount of work to preserve an artifact.
Comprehend the principle of reversibility, implying that any conservation process should, ideally, be reversible to prevent permanent alteration.
Acknowledge the precautionary principle which advocates erring on the side of caution when information about an object’s condition is uncertain.
Respect the historical significance of the piece being preserved and always consider its context when deciding on a course of action.

Recognise the importance of documenting the condition of the artifact before, during, and after the conservation process.
Develop a keen eye for assessing the macro and micro corrosion on a metal surface to determine its condition.
Understand that thorough material, structural, and surface examination provides valuable data for forming a conservation plan.
Learn to use devices such as microscopes and spectrometers to examine and assess the object more accurately.

Gain familiarity with the process of mechanical cleaning, using tools to remove loose rust and corrosion manually.
Understand how to clean metal objects using chemical methods, like acids and chelating agents.
Learn about electrolytic reduction methods for cleaning artifacts.
Appreciate the newer cleaning technology like laser technology and its application in removing surface contaminants.

Comprehend the importance of establishing a controlled environment with suitable humidity and temperature for storage of conserved pieces.
Learn to apply protective coatings such as oils, waxes or lacquers to prevent further corrosion.
Understand how to properly store and handle preserved objects to prevent physical damage from mishandling or accidents.
Lean to implement monitoring plans to regularly check restored pieces for signs of ongoing decay or corrosion.
Always remember to record and document treatment and storage details for long-term conservation purposes.
