How Do You Make Watercolors

How to Make Watercolors: A Comprehensive Guide from Pigment to Palette

Watercolors, with their luminous transparency and delicate washes, have captivated artists for centuries. This seemingly simple medium, however, hides a fascinating world of pigment chemistry, binder selection, and artistic technique. This comprehensive guide will walk you through the process of making watercolors, from sourcing raw materials to creating your own unique palette. Whether you're a seasoned artist seeking greater control over your materials or a curious beginner eager to explore the creative process, this journey into watercolor creation will deepen your appreciation for this beautiful art form.

Understanding the Components of Watercolor Paint

Before diving into the process, let's understand the core components that make up watercolor paint:

Pigment: This is the coloring agent, providing the hue and vibrancy of your watercolor. Pigments can be derived from natural sources like minerals (e.g., ultramarine blue from lapis lazuli) or synthetically produced. The quality and lightfastness of a pigment significantly impact the longevity and appearance of your artwork.
Binder: This is the substance that holds the pigment particles together and adheres them to the paper. Traditionally, gum arabic is used as a binder in watercolors due to its water-soluble nature, allowing for easy application and blending. Other binders, such as dextrin or honey, can also be experimented with, each offering slightly different properties.
Water: The solvent, water, allows for the easy manipulation of the paint’s consistency, from fluid washes to opaque impasto techniques. The quality of your water can affect the final result, so using purified or distilled water is recommended, especially for delicate washes.
Additives (Optional): Various additives can be incorporated to modify the properties of the watercolor. Honey, for example, can add a slight sheen and improve flow, while glycerin can increase the paint's plasticity. However, using too many additives can negatively impact the paint's stability and lightfastness.

Gathering Your Materials: A Watercolor Alchemist's Kit

Creating your own watercolors requires careful selection of materials. The quality of your materials directly impacts the final product, so prioritize quality over quantity.

Pigments: You can purchase pigments in powder form from art supply stores specializing in artist's materials. Research pigment properties beforehand to understand their lightfastness (resistance to fading), transparency, and granulating qualities (the tendency to create textured effects). A good starting point is to select a range of primary colors (red, yellow, blue) and a few earth tones. Remember to check for toxicity information – some pigments are more hazardous than others.
Gum Arabic: This is the heart of your binder. Choose a high-quality gum arabic specifically designed for watercolor painting. Avoid using inferior grades, as they might contain impurities that affect the paint's performance.
Mortar and Pestle: A sturdy mortar and pestle are essential for grinding pigments into a fine powder, ensuring even color distribution and preventing gritty texture in your paints.
Mixing Bowls and Palette: Clean, non-reactive bowls and a palette (glass or ceramic) will be crucial for mixing your pigments and binder.
Measuring Tools: Precise measurement is vital to consistency in your watercolor making. A small scale or measuring spoons are recommended.
Water Distiller (Optional): For best results, particularly in delicate washes, using distilled or purified water is highly recommended.
Containers for Your Finished Paints: Small, airtight containers (e.g., pans, tubes, or jars) are needed to store your handcrafted watercolors, preventing drying and preserving their quality.

The Art of Watercolor Making: A Step-by-Step Guide

Once you have gathered your materials, it's time to create your watercolors. Follow these steps carefully, maintaining cleanliness and accuracy throughout the process:

Preparing the Pigment: Start by grinding your pigment powder using a mortar and pestle. The finer the pigment, the smoother and more even your watercolor paint will be. Grind until the pigment is as fine as possible, avoiding any large, visible particles.
Mixing the Binder Solution: Dissolve your gum arabic in distilled water, following the manufacturer's instructions. The ideal consistency is usually a slightly viscous liquid, similar to honey. Avoid creating a solution that is too thin or too thick, as this can affect the paint's properties.
Creating the Watercolor Paint: Slowly add the ground pigment to the gum arabic solution. Mix thoroughly using a palette knife or a clean spatula, making sure the pigment is evenly dispersed. The amount of pigment you add determines the intensity and opacity of your watercolor. Experiment with different pigment-to-binder ratios to achieve your desired effects.
Adjusting Consistency: Monitor the consistency of the paint as you mix. If it's too thick, add a small amount of water. If it's too thin, allow some water to evaporate or add more pigment. The ideal consistency is creamy and easily spreadable without being runny.
Testing and Refining: Once mixed, test a small amount of the paint on watercolor paper to check its color, consistency, and granulation. Adjust the pigment-to-binder ratio if necessary.
Storing Your Watercolors: Once you're happy with your handmade watercolor, carefully transfer it to your chosen containers. Label each container clearly with the pigment name and date. Airtight storage is essential to prevent the paint from drying out and cracking.

Understanding Pigment Properties and Color Mixing

Different pigments exhibit unique properties. Understanding these properties is crucial for creating harmonious and vibrant watercolors.

Lightfastness: Indicates how well the pigment resists fading when exposed to light. Choose pigments with high lightfastness ratings (usually denoted by stars or grades) for archival quality.
Transparency/Opacity: Some pigments are transparent, allowing light to pass through, while others are opaque, blocking light. This affects how layers of paint interact and the overall luminosity of your work.
Granulation: Refers to the pigment's tendency to form textured deposits on the paper, creating a unique visual effect. Some pigments exhibit more granulation than others.

Knowing how pigments behave allows for creative color mixing. Experiment with combining different pigments to achieve nuanced shades and tones, pushing the boundaries of your creative palette.

Advanced Techniques and Considerations

Honey as an Additive: Adding a small amount of honey to your watercolor mixture can improve flow and add a slight sheen. Experiment with different ratios to determine the optimal effect.
Natural Pigments: Consider experimenting with natural pigments derived from plants, minerals, or insects. This provides a fascinating journey into traditional color making, though sourcing and preparation may be more challenging.
Testing for Lightfastness: After creating your watercolors, conduct a simple lightfastness test. Expose small samples of your paints to direct sunlight for an extended period to assess their resilience.
Understanding Toxicity: Always research the toxicity of the pigments you use and take necessary safety precautions, such as wearing a mask during grinding.

Frequently Asked Questions (FAQ)

How long does homemade watercolor paint last? With proper airtight storage, homemade watercolor paint can last for several years. However, the lightfastness of individual pigments will determine how well they withstand prolonged exposure to light.
Can I use other binders besides gum arabic? Yes, but gum arabic is preferred for its traditional use and compatibility with watercolor painting. Other binders like dextrin or honey can be experimented with, but they might have different properties.
How can I achieve different consistencies in my watercolors? The pigment-to-binder ratio dictates the consistency. A higher pigment ratio produces a thicker, more opaque paint, while a lower ratio results in a thinner, more transparent paint. You can also adjust the amount of water added to the mixture.
What type of paper is best for testing homemade watercolors? Use high-quality watercolor paper, preferably cold-pressed, for testing your homemade watercolors to accurately assess its properties.
What are the advantages of making your own watercolors? The primary advantages include greater control over pigment selection, the ability to create unique color combinations, and a deeper understanding of the medium.
