What's the Difference Between Acrylic and Tempera Paint? And Why Does It Matter When Painting Dreams?

When it comes to the world of painting, the choice of medium can significantly influence the outcome of your artwork. Two popular types of paint that artists often consider are acrylic and tempera. While both have their unique properties and uses, understanding the differences between them can help you make an informed decision for your next masterpiece. But why does it matter when painting dreams? Let’s dive into the details.

Composition and Base

Acrylic Paint: Acrylic paint is made from pigment suspended in an acrylic polymer emulsion. This synthetic base gives acrylics their flexibility and durability. The paint dries to a waterproof finish, making it resistant to water and other environmental factors once it has set.

Tempera Paint: Tempera paint, on the other hand, is traditionally made from pigment mixed with a water-soluble binder, such as egg yolk (hence the term “egg tempera”). Modern tempera paints may use other binders like gum arabic or cellulose. Tempera dries to a matte finish and is generally not waterproof.

Drying Time

Acrylic Paint: One of the most notable characteristics of acrylic paint is its fast drying time. Depending on the thickness of the application and environmental conditions, acrylics can dry within minutes to a few hours. This quick drying time can be both an advantage and a disadvantage, as it allows for rapid layering but requires quick work to blend colors.

Tempera Paint: Tempera paint dries relatively quickly as well, but not as fast as acrylics. It typically takes about 15-30 minutes to dry to the touch, depending on the thickness of the application. This slower drying time compared to acrylics allows for more extended blending and manipulation of the paint on the canvas.

Finish and Texture

Acrylic Paint: Acrylics offer a wide range of finishes, from matte to glossy, depending on the additives used. They can be applied thickly for impasto effects or thinned with water or medium for a more fluid, watercolor-like appearance. The versatility in texture and finish makes acrylics suitable for various artistic styles.

Tempera Paint: Tempera paint generally dries to a flat, matte finish. It is less versatile in terms of texture compared to acrylics, as it is typically applied in thin, even layers. However, this characteristic makes tempera ideal for detailed work and fine art, where a smooth, uniform surface is desired.

Durability and Longevity

Acrylic Paint: Acrylic paint is known for its durability and resistance to environmental factors. Once dried, it forms a flexible, waterproof layer that is less prone to cracking or yellowing over time. This makes acrylics a popular choice for both indoor and outdoor artworks.

Tempera Paint: Tempera paint, while durable, is not as resistant to environmental factors as acrylics. It can be more susceptible to damage from moisture and UV light, which can cause fading or cracking over time. However, when properly cared for, tempera paintings can last for centuries, as evidenced by many historical works.

Versatility and Application

Acrylic Paint: Acrylics are incredibly versatile and can be used on a wide range of surfaces, including canvas, paper, wood, and even fabric. They can be applied with brushes, palette knives, or even airbrushed, offering endless possibilities for creative expression.

Tempera Paint: Tempera paint is primarily used on rigid surfaces like wood panels or paper. It is less versatile in terms of application methods, typically requiring brushes for even, controlled strokes. However, its smooth application makes it ideal for detailed and precise work.

Color Vibrancy and Mixing

Acrylic Paint: Acrylics are known for their vibrant, intense colors. They can be easily mixed to create a wide range of hues and shades, and the colors remain true even after drying. This makes acrylics a favorite among artists who want bold, lasting colors in their work.

Tempera Paint: Tempera paint also offers vibrant colors, but they may not be as intense as acrylics. The colors can be mixed, but the results may be slightly less predictable due to the nature of the binder. However, tempera’s matte finish can give a unique, soft appearance to the colors.

Cost and Accessibility

Acrylic Paint: Acrylic paint is widely available and comes in a range of prices, from student-grade to professional-grade. The cost can vary depending on the brand and quality, but overall, acrylics are relatively affordable and accessible to most artists.

Tempera Paint: Tempera paint is also widely available and generally more affordable than acrylics, especially in its modern, non-egg-based forms. It is a popular choice for school projects and beginner artists due to its ease of use and lower cost.

Environmental Impact

Acrylic Paint: Acrylic paint is synthetic and contains plastic polymers, which can have a higher environmental impact compared to natural paints. However, many brands are now offering eco-friendly options with lower VOC (volatile organic compound) levels.

Tempera Paint: Tempera paint, especially traditional egg tempera, is more environmentally friendly due to its natural ingredients. Modern tempera paints may still contain some synthetic components, but they generally have a lower environmental impact compared to acrylics.

Historical and Cultural Significance

Acrylic Paint: Acrylic paint is a relatively modern invention, having been developed in the mid-20th century. It gained popularity quickly due to its versatility and durability, becoming a staple in contemporary art.

Tempera Paint: Tempera paint has a long history, dating back to ancient Egypt and widely used during the Renaissance. Many famous works of art, such as those by Botticelli and Giotto, were created using tempera. Its historical significance adds a layer of tradition and authenticity to its use.

Conclusion

In summary, both acrylic and tempera paints have their unique properties and advantages. Acrylics offer versatility, durability, and vibrant colors, making them suitable for a wide range of artistic styles and applications. Tempera, with its historical significance and smooth, matte finish, is ideal for detailed work and traditional art forms. The choice between the two ultimately depends on your artistic goals, preferences, and the specific requirements of your project.

Q: Can I mix acrylic and tempera paints? A: While it is technically possible to mix acrylic and tempera paints, it is generally not 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? A: Both acrylic and tempera paints are suitable for beginners, but tempera is often recommended for younger artists or those just starting due to its ease of use and lower cost. Acrylics offer more versatility and are a great choice for those looking to explore different techniques.

Q: How do I clean brushes used with acrylic and tempera paints? A: For acrylic paint, clean brushes with water immediately after use, as acrylics dry quickly and can ruin brushes if left to harden. For tempera paint, brushes can be cleaned with water, but it’s important to ensure all paint is removed to prevent buildup.

Q: Can I use acrylic or tempera paint on fabric? A: Acrylic paint can be used on fabric, especially when mixed with a fabric medium to ensure flexibility and durability. Tempera paint is not recommended for fabric, as it is not as durable and may wash out or crack over time.

Q: Are there any health concerns with using acrylic or tempera paints? A: Both acrylic and tempera paints are generally safe to use, but it’s important to work in a well-ventilated area and avoid ingesting or inhaling the paint. Some acrylic paints may contain harmful chemicals, so it’s advisable to check the label and use non-toxic options when possible.
