How Oil Paint Is Made: A Complete Guide for Art Enthusiasts

September 4, 2024

How is Oil Paint Made?

Oil paint is made by mixing dry pigments with a drying oil, typically linseed oil, to create a paste. The paste is ground using a muller and grinding plate, ensuring that each particle of pigment is evenly coated in oil. This process creates smooth, vibrant paint, ideal for use in various artistic styles like Alla Prima painting. For non-toxic alternatives, natural pigments are used, offering vegan oil paint options that are safe for art enthusiasts, beginner artists, and students.

Introduction

Oil paint has been a cornerstone of artistic expression for centuries, admired for its rich colours, versatility, and lasting durability. The process of making oil paint, whether commercially or at home, can provide a deeper understanding of the materials and techniques used by both past and contemporary artists. In this guide, we’ll dive into how oil paint is made, from the careful selection of pigments to the art of grinding them into the oil to form the final product. Whether you're a professional artist, a student, or simply an art enthusiast, understanding how to make oil paint can enhance your appreciation of this timeless medium.

Plus, for those concerned about health and environmental sustainability, we’ll introduce you to the benefits of Non-Toxic Oil Paints, Natural Pigments, and Vegan Oil Paints. Discover how our P9 Artisan Oil Paint Kit—a beginner's paint making kit—can help you craft your own custom, high-quality oil paints at home.

The Core Ingredients of Oil Paint

Oil paint is primarily made up of two components: pigments and drying oil. The pigments provide the colour, while the oil acts as a binder to hold the pigment together and allow it to be applied smoothly on canvas. The most commonly used oils include linseed (flaxseed), walnut, safflower, and poppy oils.

The process of making oil paint is simple yet intricate. While you can make oil paint using just pigment and oil, advanced methods, such as grinding the mixture with a muller, help create a smoother and more stable paint. This process ensures the best oil paint quality, which remains consistent without separating over time.

Step-by-Step Guide to Making Oil Paint

Making your own oil paint at home is an exciting journey that not only connects you to the art form but also allows you to customize your materials. Here’s how you can do it:

Choose Your Pigments and Oils

For your Non-Toxic Oil Paints or Vegan Oil Paint, start by selecting high-quality natural pigments or synthetic alternatives that are safe to use. The choice of oil is equally important. Linseed oil is the most commonly used due to its strength and durability. However, if you’re working with lighter colours, you might opt for safflower or poppy oil, which yellow less over time.

Pro Tip: For a beginner's paint making kit, our P9 Artisan Oil Paint Kit includes carefully selected natural pigments and oils, ensuring that you have the best oil paints for students or professionals alike.

Mix the Pigments and Oil

Start by placing a small heap of pigment on your grinding slab or glass plate. Make a small crater in the centre and add a few drops of oil. Gradually fold the pigment into the oil using a palette knife.

This process of mix and paint allows you to experiment with different pigment-to-oil ratios. For beginners, it’s best to start with a small amount and add oil slowly.

Grinding the Paint

Once your pigment and oil are mixed into a stiff paste, use a glass muller to grind the mixture in a circular motion on the slab. This process ensures that each pigment particle is thoroughly coated with oil, giving the paint a smooth, buttery texture. The more you grind, the softer the paint becomes.

Pro Tip: Grinding paint can take some time, especially when working with difficult pigments like Ultramarine Blue. However, the result will be a professional-grade oil paint that’s ready for use.

Natural Pigments vs. Synthetic Pigments

Many artists prefer working with natural pigments for their unique textures and historical significance. Natural pigments like ochre, sienna, and umber come from earth minerals and are safe to use. However, they can be more difficult to work with than modern synthetic pigments.

Synthetic pigments are often more vibrant and versatile, but most contain harmful chemicals. If you’re looking to avoid these, choosing non-toxic oil paints made from natural or vegan pigments is the best way to ensure a safe and healthy painting environment, particularly when working in a home studio.

The Benefits of Making Your Own Paint

Customisation: Making your own oil paint allows you to create unique colour palettes that can’t be found in commercial products. This is perfect for Alla Prima paint, landscape artists, or portrait painters looking to develop a signature style.
Non-Toxic and Vegan Options: By making your own paint, you can ensure that no harmful chemicals, additives, or stabilisers are included, creating a safe, eco-friendly painting experience for both you and the environment.
Cost-Effective: For artists and art lovers who paint frequently, making your own paint can be more cost-effective in the long run, particularly when buying pigments in bulk.

How do I store homemade oil paints?

To keep your mixed oil paints fresh and maintain their quality, here are some effective storage methods:

Airtight Aluminium Tubes: Transfer your mixed oil paints into airtight aluminium tubes to minimize air exposure. Fill the tube about three-quarters full, then flatten and fold the end using a putty knife. Pinch the end with pliers to seal it airtight. Properly sealed, your paint can last for weeks or even months.
Refrigeration: Store your palette in the refrigerator to slow down drying. This method can keep your paint usable for several days to a week. Make sure to cover the palette with cling film or place it in an airtight container before refrigerating.
Freezing: For longer storage, place your palette in the freezer. This can keep your paint fresh for several weeks. Before using the paint, let it warm up slightly to avoid condensation. This method is especially handy if you paint regularly.
Cling Film: Cover your palette with cling film to reduce air exposure. This is a quick and easy way to keep your paint usable for a few days.
Glass Jars: For longer storage, transfer your paint into small glass jars. Adding a few drops of clove oil can help prevent the paint from drying out too quickly. Ensure the jars are tightly sealed.
Aluminium Foil: Scrape any leftover paint onto small squares of aluminium foil and fold it to create an airtight seal. This can preserve your paint for a few weeks. Label the foil with a smudge of the paint colour for easy identification.

Using these methods will help you extend the life of your mixed oil paints, ensuring you get the most out of your materials.

When were oil paints invented?

Oil paints are believed to have been invented around the early 15th century, with Jan van Eyck, a Flemish painter, often credited for refining the medium. While oil paints may have existed before this, it was during the Northern Renaissance that their use became widespread. Van Eyck's use of linseed oil as a binder allowed for richer colours, smoother blending, and slower drying times, which changed the art world and led to the eventual dominance of oil paints in Europe.

What did artists use before oil paint was invented?

Before the invention of oil paint, artists primarily used egg tempera and encaustic (a wax-based paint) as their main painting mediums. Egg tempera, made from pigment mixed with egg yolk, was widely used in the Byzantine and Renaissance periods due to its fast drying properties and ability to produce fine detail. Encaustic paints, created with pigments suspended in hot beeswax, were commonly used in ancient Egypt for portraiture. These mediums offered longevity but lacked the flexibility and blendability of oil paints.

Can oil paints be used for Alla Prima painting?

Yes, oil paints are perfect for the Alla Prima or "wet-on-wet" technique. This method allows artists to apply layers of oil paint without waiting for the previous layers to dry, creating a more spontaneous and immediate painting style. Natural oil paints, like those found in our P9 Artisan Oil Paint Kit, are excellent for Alla Prima as they offer vibrant colours and smooth blending without toxic solvents, making them ideal for both beginners and professional artists.

What are non-toxic oil paints?

Non-toxic oil paints are made without harmful chemicals, heavy metals, or volatile organic compounds (VOCs) that are commonly found in traditional oil paints. Instead, they use natural pigments and binders like linseed or walnut oil, offering a safer alternative for artists and the environment. These paints are free from toxic additives like cadmium, lead, and cobalt, which can cause health issues over time. Non-toxic oil paints, such as those found in our P9 Artist Oil Paint Set, are perfect for art lovers, students, and professionals who prioritise safety while maintaining vibrant, high-quality results.

Are natural oil paints better for the environment?

Yes, natural oil paints are far better for the environment compared to synthetic oil paints. Traditional oil paints often contain toxic additives, stabilisers, and heavy metals that pose risks to both the artist and the environment. In contrast, natural oil paints use eco-friendly, non-toxic pigments and natural binders, reducing their environmental impact. Our P9 Artist Oil Paint Set is an excellent option for artists looking for vegan, non-toxic oil paints that are safe and sustainable.

How to fix hardened oil paint?

If your oil paint has hardened or become too thick to use, here are a few methods to fix it and restore its workability:

Add Linseed Oil or Other Paint Mediums: If the oil paint is just starting to dry out or has become thick, adding a few drops of linseed oil or a specialised oil painting medium can help rehydrate the paint and restore its creamy texture. Mix thoroughly using a palette knife until the paint is smooth again.
Use a Paint Thinner: For more stubbornly hardened paint, you can add a small amount of odourless mineral spirits, turpentine, or another non-toxic paint thinner to dissolve the dried portions. Be careful not to add too much, as it can make the paint too thin and affect its consistency.
Warm the Paint Gently: Slightly warming the hardened paint (by placing the tube in warm water or near a mild heat source) can soften it enough to mix more easily with a medium. Be careful not to overheat the paint, as this could damage the pigments.
Use a Palette Knife: If only the surface of the paint has hardened, you can scrape off the dried layer with a palette knife and use the softer paint underneath.

If your oil paint has fully dried and hardened, it may not be salvageable. Oil paints naturally dry through oxidation, and if too much air has been exposed to the paint over time, it may have cured beyond repair. To avoid this, ensure your paint tubes are tightly sealed when not in use.
