Chemists formulate paints used on masterpieces hanging in museums around the world. They develop makeup and special effects for theater and movie productions. They work in the music industry, developing synthetic materials for manufacturing, maintaining, repairing, and restoring.

How is chemistry used in art restoration?
Did you know there’s chemistry in art conservation? Conservators want to know the chemical composition of paints and sculptures so that they can restore damaged areas or prevent delicate materials from degrading. Sometimes they’re measuring the elements in pigments with X-rays.
What chemicals are used in art conservation?
Modern chemicals such as solvents, resins, fungicides and surfactants are essential to preserve the world’s artistic and cultural heritage.
How do you protect art from damage?
- Avoid or limit direct sunlight.
- Know when to frame with acrylic plexiglass, not glass.
- Pay attention to humidity.
- Watch your hands.
- Keep your glass or acrylics squeaky clean.
- Dust—don’t clean—your paintings.
- Don’t leave your art in a tube.
- Keep your stored artwork separated.
What processes cause damage to artwork?
Other causes of damage to art include air pollution, heat, and improper handling and storage. All of these factors may increase the chances of airborne pollutants and acids attacking the piece and causing significant damage. These elements also may lead to damage from moisture and insects as well.
What chemicals are used in art?
Painters use pigments in oil paints, acrylics, watercolor paints, gouache, encaustic, poster paints, casein paints and tempera. Sometimes commercial paints such as oil, enamel, epoxy paints and automobile paints are used.
Why is it important for an art conservator to know both chemistry and?
This unique blend of knowledge informs a conservator’s work, allowing them, in practice, to concurrently honor both the artwork’s material history (and changes to it) and the artist’s original intent.
How do you restore artwork?
- Step 1 – The Test Clean. We use an ‘Ultra Violet Light’ scan which generally shows up any previous restoration.
- Step 2 – Client Consultation.
- Step 3 – Total Clean.
- Step 4 – Stretchers and Re-Lining.
- Step 5 – Retouching.
- Step 6 – Varnishing and Finishing.
What is chemical conservation?
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
What solvents are used in art restoration?
How an artwork is cleaned will depend on the nature of the material to be removed. With paintings, a variety of organic solvents are used, but the most common solvent is water, often with chelating agents, surfactants or salts to control pH.
How is ancient art preserved?
Contract conservators maintain these artworks on a regular schedule. They wash them to remove abrasive and corrosive debris, which accumulates due to outdoor exposure, and cover them with protective wax coatings.
What is the purpose of a forgery?
Any alteration or modification of an official document, such as a state-issued identification or locally issued permit, with intent to defraud, could be considered forgery. Typically, the purpose of creating a forgery is to try to pass it off as genuine in order to obtain services, money, or something else of value.
How do you protect framed paintings with acid-free tissue?
Use acid-free packaging such as tissue paper or glassine. You can bubble wrap your artwork for storage and transportation but leave it slightly open so it can breathe. Store your paintings vertically, rather than horizontally and do not stack them.
How do you protect unframed artwork?
For unframed pieces Use a sheet of silicone release paper to cover the canvas and seal it with packing tape, ensuring that no tape makes contact with the canvas. If you can’t find silicone paper, a clean plastic sheet works too.
How do you protect an acrylic painting?
Cover your painting in glass so it’s in a protective frame. Placing a frame with glass in it will protect your acrylic painting from dust and dirt, as well as any accidental touches. If you’re worried about sun damage, opt for a UV-protected plastic that looks similar to glass so your painting won’t fade as easily.
What can damage paintings?
Extreme temperature and humidity or fluctuations in their levels damage paintings and frames because their multiple layers expand and contract as moisture spreads into or out of the surrounding air.
What causes art deteriorate?
Exposure to elevated temperatures will accelerate chemical deterioration and may also cause paint binders to soften or break down. Over-exposure to light is a major cause of deterioration for displayed artworks.
How do I protect my paintings from humidity?
If possible, hire an art logistics company offering professional art packing and crating services to eliminate any risk of damage. If not, after wrapping your artwork in glassine paper, cover it with special art plastic that is 4mm plastic used for moisture protection.
What is the relation between art and chemistry?
Chemistry and art are often thought of as polar opposites. Whilst art is seen as being creative, expressive and fluid, chemistry is analytical, precise and staid. But there is, in fact, a significant crossover between the two subjects.
How is paint made chemistry?
Emulsion paints dry by a physical process involving the evaporation of water followed by coalescence of the polymer droplets and their subsequent integration into a hard polymer matrix that acts as a binder for the pigment.
Which chemical is used in paint?
The chemicals discussed below are common components of paints: benzene, toluene, chlorinated solvents (dichloromethane, trichloroethylene), xylenes, metals (cadmium, chromium, inorganic lead), styrene, PAHs, and aromatic azo dyes.
How are paintings conserved?
Conservation treatments can take the form of adhering a lining to the canvas with wax-resin to the reverse side, replacing the painting’s original stretcher, and varnishing the painting. In Jackson Pollock’s Echo, solvents were used to remove a thin layer of the canvas to even out the work’s coloring.
What does an art conservationist do?
An art conservator analyzes and restores different art objects and artifacts so they can last for years to come. Using their art knowledge and attention to detail, they determine whether they can salvage and preserve a work of art.
What qualifications do you need to be an art restorer?
Education, Training & Certification Many employers may require that you have at least a bachelor’s degree in art conservation or a similar subject area. Coursework: If you decide to study fine art restoration, focus on courses like chemistry, anthropology, studio art, and art history.
Why do we need to keep preserve and restore art?
Art restoration is intended to preserve the integrity (and thus, value) of an original work of art. Many in need of repair, however, date back centuries, and the inevitable decay from time and climatic conditions can have a significant impact on their current value in the art market.
