When it comes to painting, the choice of medium can significantly influence the final outcome of an artwork. Two popular types of paint that artists often consider are tempera and acrylic. While both have their unique characteristics and applications, they differ in composition, drying time, texture, and versatility. Understanding these differences can help artists make informed decisions about which medium to use for their projects.
Composition and Ingredients
Tempera Paint: Tempera paint, also known as egg tempera, is one of the oldest painting mediums, dating back to ancient Egypt and widely used during the Renaissance. The traditional form of tempera is made by mixing pigment with a water-soluble binder, typically egg yolk. This mixture creates a fast-drying, durable paint that adheres well to surfaces like wood panels and canvas.
Acrylic Paint: Acrylic paint, on the other hand, is a relatively modern invention, developed in the mid-20th century. It is made from pigment suspended in an acrylic polymer emulsion. This synthetic binder gives acrylic paint its flexibility, water resistance, and quick-drying properties. Acrylics can be used on a variety of surfaces, including canvas, paper, wood, and even metal.
Drying Time
Tempera Paint: One of the most notable differences between tempera and acrylic paint is their drying time. Tempera paint dries very quickly, often within minutes. This rapid drying time can be both an advantage and a disadvantage. On the one hand, it allows artists to work quickly and build up layers without waiting long periods. On the other hand, it can make blending and reworking areas more challenging.
Acrylic Paint: Acrylic paint also dries quickly, but not as fast as tempera. Depending on the thickness of the application and environmental conditions, acrylics can take anywhere from a few minutes to several hours to dry. This slightly longer drying time gives artists more flexibility to blend colors and make adjustments before the paint sets.
Texture and Finish
Tempera Paint: Tempera paint typically dries to a matte finish with a smooth, even texture. Because it is water-soluble, it can be thinned with water to create translucent washes or applied more thickly for opaque coverage. However, tempera is not as flexible as acrylic, and it can become brittle over time, especially if applied in thick layers.
Acrylic Paint: Acrylic paint offers a wide range of finishes, from matte to glossy, depending on the additives used. It can be applied thinly for a watercolor-like effect or thickly for impasto techniques. Acrylics are known for their flexibility, which makes them less prone to cracking over time. Additionally, acrylic paint can be mixed with various mediums to alter its texture, drying time, and finish.
Versatility and Applications
Tempera Paint: Tempera paint is often favored for its historical significance and the unique qualities it brings to traditional art forms. It is particularly well-suited for detailed work, such as icon painting or miniature art, where precision and fine lines are essential. However, tempera is less versatile than acrylic when it comes to modern applications, as it is not as durable or adaptable to different surfaces and techniques.
Acrylic Paint: Acrylic paint is highly versatile and can be used in a wide range of artistic styles and techniques. It is suitable for both fine art and commercial applications, including murals, illustrations, and even fabric painting. Acrylics can be used with various tools, from brushes and palette knives to airbrushes, and they can be mixed with other mediums to create unique effects. This versatility makes acrylic paint a popular choice among contemporary artists.
Durability and Longevity
Tempera Paint: Tempera paint is known for its durability, especially when applied to properly prepared surfaces. However, because it is water-soluble, it is more susceptible to damage from moisture and humidity. Over time, tempera paintings may require careful conservation to prevent cracking and flaking.
Acrylic Paint: Acrylic paint is highly durable and resistant to environmental factors such as moisture and UV light. Once dried, acrylic paint forms a flexible, waterproof layer that is less likely to crack or fade over time. This makes acrylic paintings more suitable for long-term display and less demanding in terms of conservation.
Cost and Accessibility
Tempera Paint: Tempera paint is generally more affordable than acrylic paint, making it an attractive option for artists on a budget or for educational purposes. However, high-quality tempera paints, especially those made with natural pigments, can be more expensive and harder to find.
Acrylic Paint: Acrylic paint is widely available in a range of prices, from student-grade to professional-grade. While high-quality acrylics can be more expensive, they offer greater versatility and durability, which can justify the higher cost for many artists.
Environmental Impact
Tempera Paint: Traditional tempera paint, made with natural ingredients like egg yolk, is generally considered more environmentally friendly than synthetic paints. However, some modern tempera paints may contain additives or preservatives that can be harmful to the environment.
Acrylic Paint: Acrylic paint is made from synthetic materials, which can have a higher environmental impact. The production and disposal of acrylic paint can contribute to pollution, and some acrylic paints contain toxic chemicals that can be harmful if not handled properly. However, there are eco-friendly acrylic paint options available that use non-toxic, biodegradable ingredients.
Conclusion
In summary, both tempera and acrylic paints have their unique advantages and disadvantages. Tempera paint offers a traditional, matte finish with a quick drying time, making it ideal for detailed work and historical art forms. Acrylic paint, with its versatility, durability, and wide range of finishes, is better suited for modern applications and artists looking for flexibility in their work. Ultimately, the choice between tempera and acrylic paint depends on the artist’s specific needs, preferences, and the desired outcome of their artwork.

Q: Can tempera paint be used on canvas? A: Yes, tempera paint can be used on canvas, but it is more commonly applied to rigid surfaces like wood panels. When used on canvas, it is important to properly prepare the surface to ensure good adhesion.
Q: Is acrylic paint waterproof once dry? A: Yes, acrylic paint becomes waterproof once it dries, making it suitable for outdoor applications and surfaces that may be exposed to moisture.
Q: Can you mix tempera and acrylic paint? A: While it is possible to mix tempera and acrylic paint, it is not generally recommended. The different binders and drying times can lead to unpredictable results and potential issues with the paint’s durability.
Q: Which paint is better for beginners, tempera or acrylic? A: Both tempera and acrylic paints are suitable for beginners, but acrylics are often recommended due to their versatility, ease of use, and wide range of available resources and tutorials.
Q: How do you clean brushes used with tempera paint? A: Brushes used with tempera paint can be cleaned with water and mild soap. It is important to clean them thoroughly to prevent the paint from drying and hardening on the bristles.
Q: Can acrylic paint be used for fine detail work? A: Yes, acrylic paint can be used for fine detail work, especially when thinned with water or acrylic mediums. However, some artists prefer tempera for extremely fine lines due to its quick drying time and smooth application.
