What You'll Learn
Turpentine is a natural solvent
As a solvent, turpentine is fast-evaporating and highly sought after by artists for its ability to improve paint flow and reduce drying time. It is also used in primer coats, where it helps create a thinner paint that is easier to brush and apply in thin coats. However, it is essential to use turpentine sparingly and in well-ventilated areas due to its potential health risks.
Turpentine has a variety of uses beyond the artistic realm. It is used in the chemical industry as a raw material for synthesising resins, insecticides, oil additives, synthetic pine oil, and camphor. Additionally, it serves as a rubber solvent in plastic manufacturing. In the past, turpentine was even used medicinally, both topically and internally, for treating various ailments.
The quality and purity of turpentine can vary depending on its source and production method. Gum turpentine, derived from the distillation of living pine trees, is considered the purest form. However, it is important to distinguish it from crude turpentine, which may refer to the raw, unprocessed resin. Sustainable practices have been adopted to ensure the health and longevity of the trees while producing high-quality turpentine.
Despite its natural origins, turpentine is a hazardous substance that requires careful handling. It is toxic and can cause skin and eye irritation, allergic reactions, and respiratory issues. Traditional methods of extraction, such as destructive distillation of pine wood, have been replaced by more sustainable practices that focus on ecological responsibility.

It is toxic and volatile
Pure gum spirits of turpentine is toxic and highly volatile. It is a natural solvent distilled from pine tree resins and has traditionally been used for thinning oil-based paints, varnishes, and mediums in art. While it is effective in improving paint flow and drying time, it can cause serious health issues if not used with caution.
Turpentine is classified as a hazardous substance due to its high volatility and chemical reactivity. It is a flammable liquid and vapour, and its concentrated vapours can cause headaches. If ingested, inhaled, or if it comes into contact with skin, it can be harmful and even fatal. It can also cause skin and eye irritation and serious eye damage.
Due to its toxic nature, it is important to take necessary precautions when using turpentine. It should be stored and used in a well-ventilated area to prevent the inhalation of concentrated vapours. It is advised to avoid breathing dust and to wash exposed skin thoroughly after handling turpentine. It should not be ingested, and proper safety measures should be followed to prevent accidental ingestion or inhalation.
The toxicity of turpentine can vary depending on the source and distillation process. The gum turpentine sold in small, expensive cans in art supply stores is typically a purer and more refined version than the larger cans found in hardware stores. However, if the product is labelled as ""pure gum spirits of turpentine", it should be the same material, regardless of the container size.
Despite the health risks associated with turpentine, some artists prefer to use it for thinning oil paints due to tradition and its effectiveness as a solvent. However, there are alternative options available, such as mineral spirits, which are just as effective for thinning paints and varnishes. These alternatives may be safer to use, but it is important to note that they can still be toxic and require proper ventilation.

Turpentine improves paint flow and drying time
Turpentine is a natural solvent that improves paint flow and drying time. It is a traditional, fast-evaporating solvent distilled from pine resin. When used as a thinner for oil-based paints, turpentine helps improve the flow of the paint, making it easier to brush and apply thin coats. This results in faster drying times as there is less paint or oil on the surface, reducing the curing time.
Pure gum spirits of turpentine, obtained by distilling the sap from living pine trees, is a preferred choice for artists due to its high purity and effectiveness in thinning oil paints, varnishes, and mediums. It has more solvency than mineral spirits or odourless mineral spirits, making it ideal for thinning and improving paint flow.
However, it is important to use turpentine sparingly and with good ventilation due to its potential health hazards. Turpentine is highly volatile and can cause skin irritation, eye damage, respiratory irritation, and allergic reactions in some individuals. It is also flammable and can be harmful if swallowed. Therefore, it is crucial to follow safety precautions and handle turpentine with caution.
As an alternative to turpentine, some artists use mineral spirits or odourless mineral spirits for thinning oil paints. These options are equally effective for thinning paint and are considered less toxic. Additionally, some artists explore natural alternatives, such as sunflower oil or a mix of safflower oil and clove oil, for cleaning brushes, although these methods may extend the drying time.
In conclusion, turpentine is valued for its ability to improve paint flow and drying time, making it a popular choice among artists for thinning oil paints. However, due to its potential health risks, it should be used with caution and adequate ventilation. Artists have alternative options, such as mineral spirits or natural alternatives, to consider based on their preferences and safety considerations.

It is used for thinning oil-based paints
Pure gum spirits of turpentine is a traditional, fast-evaporating solvent distilled from pine resin. It is commonly used for thinning oil-based paints and varnishes in art due to its high solvent strength and ability to improve paint flow and drying time. It is also used to clean tools such as brushes, rollers, spray equipment, and roller trays.
When used for thinning oil-based paints, pure gum spirits of turpentine helps to create a thinner paint that is easier to brush and lay down thin coats. It also improves the bonding and penetration of most brush-applied alkyd and oil-type paints. The high solvent strength of gum turpentine also makes it effective in thinning varnishes and mediums used in art.
To thin paint with pure gum spirits of turpentine, you can add 9.6 fl oz of turpentine to 1 quart of paint and roughly 22 oz of oil to yield 2 quarts of primer. This will give you a thinned primer coat that can cover around 650-800 square feet per gallon, depending on the porosity and texture of the surface.
It is important to note that pure gum spirits of turpentine is a hazardous substance and should be used with caution. It is highly volatile and chemically reactive, and can cause skin irritation, eye irritation, and serious health issues if inhaled, swallowed, or comes in contact with skin. It is classified as a flammable liquid and vapor, and should be stored and handled with care. When working with pure gum spirits of turpentine, it is important to ensure good ventilation and follow all safety instructions on the product label.

Turpentine is a better thinner than mineral spirits
Turpentine is a natural solvent distilled from pine resin and has been used for various purposes since the 1800s. It is a traditional, fast-evaporating thinner for oil-based paints and varnishes, and it can also be used for cleaning tools. When used as a thinner, it improves paint flow and drying time.
Mineral spirits, on the other hand, are petroleum distillates commonly used as paint thinners. While they are effective, they are not as compatible with oil paints as turpentine and have a slower drying time. This gives mineral spirits an advantage in terms of workability, especially in wipe stains.
One of the main reasons why turpentine is considered superior to mineral spirits is its higher solvency power. Turpentine has more solvency than mineral spirits, making it more effective at thinning oil-based paints and varnishes. It is also a better solvent for oil-based finishes, although it may not be as readily available as mineral spirits or paint thinner.
Another advantage of turpentine is its natural origin. Many artists prefer it for its purity and the fact that it is derived from pine trees, making it a more environmentally friendly option. Sustainable production methods involve tapping the slash pine trees to extract raw pine gum without damaging the tree's trunk, preserving the natural environment and ensuring the forest's health and longevity.
However, it is important to note that turpentine comes with significant health and safety warnings due to its high volatility and chemical reactivity. It can cause skin irritation, allergic reactions, and headaches from concentrated vapours. Similarly, mineral spirits vapours are also considered toxic. Therefore, adequate ventilation and caution are necessary when working with either of these substances.
