The goal of ensuring that well-known pieces of art stay accessible has driven the history of art restoration for centuries. Since the famed Sistine Chapel frescoes of Michelangelo were first restored in the 16th century owing to water damage, technological advancements have resulted in the creation of increasingly safe and efficient methods for preserving and repairing a variety of works.
An original work of art's integrity and worth are supposed to be preserved during restoration. However, many that require repair are centuries old, and the natural deterioration brought on by time and environmental factors can significantly affect their current worth in the art market.
However, with museums and local government working ceaselessly to clean and safeguard cultural assets, art restoration has grown in significance. A full-time scientist is employed by the Metropolitan Museum of Art, the Museum of Modern Art and The Getty to create specialized conservation strategies.
Art restoration is a field that is always developing in order to preserve the historical relevance of the most important pieces of art, regardless of whether they are harmed unintentionally, purposefully, or naturally over time.
What is Art Restoration?
Any effort to conserve and repair works of fine and decorative art that have undergone negative alterations includes architecture, paintings, drawings, sculptures, and other such artifacts. Although they are closely related, conservation techniques and art restoration have slightly different definitions.
While conservation refers to the upkeep and preservation to guard against further harm and degradation, art restoration signifies the repair or renovation of works that have already suffered decay in an effort to return work to its former, undamaged appearance.
A painting may need to be repaired for a variety of reasons. For instance, a $1.5 million oil painting of "Flowers" in the Baroque style by Paolo Porpora was unintentionally damaged in 2015 after a twelve-year-old child lost his balance. In addition, "The Night Watch," a well-known Rembrandt van Rijn piece on display at the Rijksmuseum in Amsterdam, has seen three deliberate vandalism incidents.
Other artworks, such as "The Resurrection" (1465) and "The Last Supper" (1546), were created with transitory paint or were subjected to environmental factors that expedited the deterioration of their state.
The Process
The appropriate processes and procedures for each painting must be carefully considered because there is no "one size fits all" method for painting restoration. To examine a work's original components and choose the least invasive way to restore damage, trained art historians, chemists, and materials scientists pool their enormous expertise.
The painting first goes through a preliminary evaluation. As this information will help establish painting techniques, resources available to painters at the time, and colors and fabrics that were regularly employed, conservation associates should be well-versed in the style and era of the piece they are examining. The composition of the work is also revealed by X-rays, which enables the conservator to create an outline of the painting or work based on variations in paint absorption.
The original sketches and paint losses beneath the surface of a painting can then be seen via infrared imaging. Recently, cameras with set wavelengths have been developed for use in art restoration. These tools can assist distinguish them because different colors and materials reflect or absorb specific wavelengths in different ways. Using specific wavelengths at roughly 1,700 nanometers, they enable conservators to identify carbon-based drawings, for instance. This is a part of a bigger trend to get rid of old harmful methods and make it easier to see varnish layers.
Finding the right solvent mixture to remove stained varnish layers, if necessary, comes after creating an accurate representation of the original artwork.
Since then, it has become simpler to ascertain the precise composition and characterization of varnishes thanks to the invention of spectroscopy, a method used to study vibrational, rotational, and other low-frequency modes in a system.
It is possible to fix the varnish after identifying it and removing its outer layers. Here is an illustration of how this might be accomplished in current usage: To physically separate the new paint from the old and ensure that any upcoming restorations may be completed without harming the work's original layers, an intermediate coat of varnish is added to the original painting.
This permits stylistic changes, which are frequent in the conservation of artwork. To ensure that a well-restored piece rarely needs additional conservation, the conservator will carefully inpaint damaged areas using dry pigment mixed with synthetic non-yellowing solvents.
The Cost
Depending on a piece's condition, the degree of its damage, and its size, the price to restore it varies substantially. Sophisticated (and expensive) equipment like as x-ray machines, which can cost hundreds of thousands of dollars, is available to museums with specialized departments. Usually, independent conservators send samples to laboratories for scientific evaluation.
"In the public realm, conservators will have an hourly rate, and a conservation treatment will either be charged according to that rate or a total project cost," says Nicholas Dorman, Chief Conservator of the Seattle Art Museum. Cleanings to more comprehensive restorations that can cost thousands of dollars are examples of projects. Insurance coverage frequently covers treatments when dealing with more expensive paintings, as was the case for the well-publicized restoration of the Paolo Porpora painting.
