Understanding Tempera Paint: A Brief History and Its Appeal
Before we dive into the mixing, let’s understand what tempera paint actually is. Tempera, derived from the Latin word “temperare” meaning “to mix in proportion,” refers to a permanent, fast-drying painting medium consisting of colored pigment mixed with a water-soluble binder.
Historically, egg tempera was the dominant painting method for centuries, particularly during the Renaissance. Artists like Botticelli used egg yolk as the primary binder, creating luminous, detailed works. Modern tempera, often called “poster paint,” uses different binders like gum arabic, casein, or starch, making it more accessible and versatile for general use.
Why Make Your Own Tempera Paint?
There are several compelling reasons to learn how to make tempera paint yourself:
- Control Over Ingredients: You know exactly what goes into your paint, which is especially important for child-safe options.
- Cost-Effective: Homemade tempera is significantly cheaper than store-bought versions, especially for large projects.
- Customization: Adjust consistency, color intensity, and even additives to suit your specific artistic vision.
- Educational Fun: It’s a fantastic science experiment for kids, teaching them about colors and materials.
- Sustainable Choice: Reduce waste by using bulk ingredients and reusing containers.
This makes homemade tempera a perfect fit for garage tinkerers, DIY homeowners looking for craft solutions, and anyone who appreciates the value of creating with their own hands.
Essential Ingredients for Homemade Tempera Paint
The beauty of making your own tempera paint lies in its simplicity. You only need a few core components, which you likely already have around the house or can easily acquire.
The Pigment: Your Source of Color
The pigment is what gives your paint its color. For homemade tempera, you have several options:
- Powdered Pigments: These are the most common and professional choice. You can find them at art supply stores or online. They offer intense, true colors.
- Natural Dyes: Spices like turmeric (yellow), paprika (red/orange), or spirulina powder (green/blue) can work. Food colorings are also an option, though they might fade over time.
- Food-Grade Options: For ultimate safety, especially for very young children, stick to food-grade powdered food colorings or natural food dyes.
When working with powdered pigments, always wear a dust mask to avoid inhaling fine particles. Some pigments can be irritants.
The Binder: Holding it All Together
The binder is the crucial ingredient that adheres the pigment to the surface once the water evaporates. It also affects the paint’s texture and durability.
- Cornstarch: A popular, inexpensive, and readily available binder for DIY tempera. It creates a smooth, opaque paint.
- Flour: Another common kitchen staple, flour works similarly to cornstarch. It can sometimes result in a slightly grainier texture.
- Egg Yolk: The traditional binder for true egg tempera. While it produces a beautiful, durable finish, it has a very short shelf life and requires immediate use.
- Gum Arabic: A more professional binder, often found in watercolor paints. It creates a more stable, translucent paint with better permanence and shelf life than starch-based options.
For most DIY projects and kid-friendly paints, cornstarch or flour are excellent starting points.
The Liquid: Water is Your Solvent
Water is essential to dissolve the binder and pigment, allowing the paint to flow.
- Distilled Water: Recommended for better shelf life, especially if you plan to store your paint. It’s free of impurities that could encourage mold growth.
- Tap Water: Perfectly fine for paint you plan to use immediately.
Optional Additives for Enhanced Performance
A few extra ingredients can improve your paint’s texture, flow, and longevity.
- Glycerin: Adding a small amount of glycerin (available at pharmacies or craft stores) can make your tempera paint more flexible, preventing cracking as it dries. It also gives it a smoother consistency.
- Preservatives: If you want your homemade paint to last more than a few days, a natural preservative is key. A few drops of clove oil or a teaspoon of white vinegar can inhibit mold growth, especially in organic binders like cornstarch or flour.
- Dish Soap: A tiny drop of liquid dish soap can improve the paint’s flow and make cleanup easier.
These additives are not strictly necessary, but they can significantly enhance your painting experience.
Step-by-Step: How to Make Tempera Paint with Cornstarch (Beginner-Friendly Method)
This is the easiest and most popular method for creating non-toxic, kid-friendly tempera paint. It’s quick, uses common household ingredients, and yields great results.
Gather Your Tools and Materials
Before you begin, ensure you have everything within reach.
- Measuring Cups and Spoons: For accurate ingredient ratios.
- Mixing Bowls: One for the binder, separate small bowls for each color.
- Whisk or Spoon: For thorough mixing.
- Airtight Containers: Small jars or plastic containers for storing your finished paint.
- Small Saucepan: If you’re heating the cornstarch binder.
- Ingredients:
- ½ cup cornstarch
- ½ cup cold water
- 1 cup hot water (boiled and slightly cooled)
- Powdered pigments or food coloring
- Optional: ½ teaspoon glycerin, ½ teaspoon white vinegar or a few drops of clove oil
Preparing the Binder Base
The cornstarch binder needs to be cooked slightly to achieve the right consistency.
- In a saucepan, whisk together the ½ cup of cornstarch and ½ cup of cold water until smooth. Ensure there are no lumps.
- Place the saucepan over medium heat. Slowly pour in the 1 cup of hot water, stirring continuously.
- Continue to stir until the mixture thickens into a gel-like consistency, similar to a thin pudding or gravy. This usually takes 2-5 minutes. Don’t let it boil vigorously.
- Remove the saucepan from the heat and allow the binder to cool completely. This cooling step is crucial; warm binder can affect pigment consistency.
- Once cool, stir in the optional ½ teaspoon of glycerin (if using) for added flexibility and smoothness.
You now have your basic, neutral binder ready for color.
Mixing in Your Pigments
This is where the magic happens and your paint comes to life!
- Divide your cooled cornstarch binder into separate small bowls, one for each color you want to create.
- Add your chosen powdered pigment or food coloring to each bowl, starting with a small amount (e.g., ½ teaspoon of pigment powder).
- Stir the pigment into the binder thoroughly. Mix until the color is evenly distributed and there are no streaks.
- Adjust Consistency: If the paint is too thick, add a few drops of water at a time until you reach your desired consistency. If it’s too thin, you can add a tiny bit more cornstarch binder (if you have extra) or a small pinch of powdered pigment (which also adds body).
- Adjust Color: If the color isn’t vibrant enough, add more pigment gradually until you achieve the desired hue.
Remember, a little pigment goes a long way, especially with concentrated powders. Always add gradually.
Adding Preservatives and Storing Your Paint
To extend the life of your homemade tempera, especially if you’re not using it all at once, add a preservative.
- To each bowl of colored paint, add a few drops of clove oil or ½ teaspoon of white vinegar. Mix well. This helps inhibit mold growth.
- Transfer your finished tempera paint into clean, airtight containers. Small canning jars or recycled plastic food containers work perfectly.
- Label each container with the color and date of creation.
- Store your homemade tempera paint in the refrigerator. This is essential, especially with organic binders, to prevent spoilage.
Following these steps will ensure you know precisely how to make tempera paint that’s ready for any creative endeavor.
Exploring Other Tempera Paint Recipes
While cornstarch tempera is a fantastic starting point, there are other methods for making this versatile paint, each with its own characteristics.
Egg Tempera: The Traditional Artist’s Choice
Egg tempera is historically significant and produces a highly durable, luminous finish. It’s not typically what people mean by “tempera paint” in a craft store, but it’s worth exploring for serious artists.
- Recipe: Separate an egg yolk, carefully removing any albumen (egg white). Place the yolk in a small dish and pierce the membrane. Discard the membrane, leaving just the pure yolk. Mix a small amount of yolk with powdered pigment and a few drops of distilled water.
- Characteristics: Dries very quickly to a matte, opaque finish. Colors are vibrant and can be layered for glazing effects.
- Shelf Life: Extremely short. Egg tempera must be used immediately, as it spoils rapidly. This is not a paint to store!
Flour-Based Tempera: A Kid-Friendly Alternative
Similar to cornstarch, flour can also serve as a binder, offering another simple and inexpensive option.
- Recipe: Whisk together 1 cup of all-purpose flour with 1 cup of cold water until smooth. Slowly add 2 cups of boiling water, whisking constantly, until the mixture thickens. Let it cool, then mix with pigments as described in the cornstarch method.
- Characteristics: Produces a thicker, often slightly grainier paint. Great for finger painting or large-scale projects where texture isn’t a primary concern.
- Shelf Life: Similar to cornstarch tempera, requires refrigeration and a preservative for more than a few days of storage.
Gum Arabic Tempera: For Finer Art and Durability
Gum arabic is a natural gum extracted from acacia trees and is a common binder in watercolors and gouache. It offers better permanence and a smoother finish than starch-based options.
- Recipe: Dissolve gum arabic powder (available at art supply stores) in distilled water to create a liquid binder (e.g., 1 part gum arabic powder to 2 parts water, let it sit overnight to fully dissolve). Then, mix this liquid binder with powdered pigments.
- Characteristics: Dries to a smooth, semi-gloss finish. Offers excellent adhesion and lightfastness, making it suitable for more permanent artworks.
- Shelf Life: Gum arabic solutions, especially with a preservative like a few drops of clove oil or a commercial preservative, can last for weeks or even months in the refrigerator.
Each of these methods provides a slightly different painting experience, allowing you to choose the best option based on your project and desired outcome.
Tips for Using and Storing Your Homemade Tempera
Making your own paint is only half the battle; knowing how to use and care for it will ensure your creative projects are a success.
Consistency Adjustments
- Too Thick? Add a few drops of water at a time and stir well until you reach your desired flow.
- Too Thin? If you have extra binder, add a small amount. Otherwise, a tiny pinch of powdered pigment can also add body. Be careful not to add too much, or you’ll intensify the color.
Applying the Paint
- Brushes: Tempera works well with synthetic or natural hair brushes. Clean them immediately after use.
- Sponges: Great for creating textured effects or covering large areas quickly.
- Finger Painting: The cornstarch or flour-based recipes are ideal for young children’s finger painting, as they are non-toxic and easy to clean.
Drying Time and Finish
Homemade tempera paint typically dries quickly, often within minutes, depending on the thickness of application and humidity. It dries to an opaque, matte finish. If you desire a slightly glossier finish, you can add a tiny amount of liquid dish soap or a few drops of acrylic medium to the paint.
Proper Storage for Longevity
As mentioned, proper storage is critical for homemade tempera, especially with organic binders.
- Always store in clean, airtight containers.
- Refrigeration is key for cornstarch and flour-based paints. They can last 1-2 weeks this way, especially with a preservative.
- Egg tempera should be used immediately.
- Gum arabic tempera will last longer, but refrigeration is still recommended.
- If you notice any mold or an off smell, discard the paint immediately.
Troubleshooting Common Issues
- Cracking: If your paint cracks as it dries, it might be applied too thickly, or the binder might be too stiff. Try adding a bit more glycerin or thinning the paint with a few drops of water.
- Uneven Color: Ensure you stir the paint thoroughly before each use, as pigments can settle over time.
- Mold: This indicates insufficient preservative or improper storage. Always refrigerate and consider adding clove oil or vinegar.
Safety Considerations
While we’re focusing on non-toxic options, always supervise young children when they are painting. Ensure they understand not to ingest the paint, even if it’s made with food-grade ingredients. Some pigments, even natural ones, can cause skin irritation in sensitive individuals. Always test a small amount first.

Frequently Asked Questions About How to Make Tempera Paint
Here are some common questions DIYers have when learning how to make tempera paint.
Can I use food coloring instead of powdered pigments?
Yes, you can absolutely use liquid food coloring or powdered food dyes. They are generally very safe and easy to find. However, be aware that food coloring can sometimes fade over time, especially when exposed to direct sunlight. Powdered pigments tend to offer more vibrant and lightfast colors for more lasting art.
How long does homemade tempera paint last?
With proper storage (airtight containers in the refrigerator) and the addition of a preservative like white vinegar or clove oil, cornstarch or flour-based tempera paint can last for 1 to 2 weeks. Without a preservative, it might only last a few days. Egg tempera must be used immediately as it spoils very quickly.
Is homemade tempera paint truly non-toxic?
If you use food-grade ingredients like cornstarch, flour, water, and food coloring or natural food dyes (like turmeric or spirulina), your homemade tempera paint can be considered non-toxic. Always double-check the labels of any powdered pigments you use, as some art pigments can contain heavy metals or other irritants. Supervision is always recommended for young children.
What’s the best way to clean up tempera paint?
Homemade tempera paint is generally very easy to clean up. It’s water-soluble, so simply use warm water and soap for brushes, hands, and surfaces. For fabric stains, try to rinse immediately with cold water before the paint dries, then wash as usual. The ease of cleanup is one of its major advantages, especially for kid-friendly projects.
Why is my tempera paint cracking?
Cracking usually occurs if the paint is applied too thickly or if the binder-to-pigment ratio is off, making the paint too stiff. To prevent this, try applying thinner layers of paint. You can also add a small amount of glycerin (about ½ teaspoon per cup of binder) to your paint mixture; glycerin helps make the paint film more flexible and less prone to cracking as it dries.
Making your own tempera paint is a fantastic way to engage with your creative side, save money, and ensure you’re using safe materials. It embodies the DIY spirit, transforming simple ingredients into vibrant tools for expression. Experiment with different binders and pigments, find your favorite recipes, and inspire yourself and those around you to create.
