Introduction to Acrylic and Watercolor Paints
Acrylic is a fast-drying, water-based paint used by most artists. Acrylic paint is also known as acrylic resin, acrylate resin, polymethyl methacrylate, Acrilan, synthetic resin, and more. It was invented by Otto Rohm and introduced around 1934 by Leonard Bocour and Sam Golden. Famous artists like Andy Warhol, David Hockney, and Robert Motherwell later used acrylics in their work.
On the other hand, watercolor is also a fast-drying, water-soluble paint, but its drying time is shorter compared to acrylics. Watercolors painted with water-soluble color inks instead of modern watercolors are called aquarellum atramento. Watercolor paintings have ancient origins, possibly dating back to Europe's Paleolithic Age. Its history as an artistic medium stretches back to the Renaissance, around the 15th century. Albrecht Dürer, a Northern German Renaissance painter known for his stunning watercolors of flowers, animals, and landscapes, is widely regarded as one of the founding fathers of watercolor painting. Hans Bol founded an influential watercolor painting school in Germany during the Dürer Renaissance.
Composition of Acrylic and Watercolor Paints
Acrylic paint is a type of synthetic polymer extracted from petroleum and natural gases. Acrylic paints are made by suspending pigments in water-soluble acrylic resins or acrylic polymer emulsion, along with plasticizers, silicon oils, defoamers, stabilizers, or metal soaps.
In contrast, watercolor paints are made up of four major ingredients: glycerin, bovine bile, honey, and preservatives. These ingredients vary the viscosity, concealing power, stability, or color of the pigment carrier mixture. Water acts as a solvent to reduce the thickness of the paint before application.
Specific Properties of Acrylic and Watercolor Paints
Acrylic paint is soluble in water but becomes water-resistant when dried. Additionally, acrylic paint can resist heat better than other types of paints. The beauty of acrylic paint lies in its ability to provide both the transparency of watercolor and the texture of oil paint. This versatility makes acrylic paint a popular choice for artists.
Watercolors, made up of water-soluble pigments and binders, expand and create a blurred or fuzzy effect when in contact with water. One of the most appealing features of watercolor is the ability to achieve transparency and shine by adding layers. Artists can use watercolors to produce unique paintings that creatively express their imagination.
Key Features of Acrylic and Watercolor Paints
Depending on the amount of water used to dilute the paint or the density of acrylic gels or paste, a completed acrylic painting might resemble a watercolor, gouache, or oil painting, or have its own distinct features not achievable with other media.
In contrast, the saturation of watercolor paintings can be improved by applying multiple layers or using watercolor stainers like Prussian blue and watercolor binders.
Suitable Surfaces for Acrylic and Watercolor Paints
Acrylic paint can bond to many different surfaces, and mediums can modify their binding characteristics. Acrylics can be used on paper, canvas, and a range of other materials. Acrylic painting on canvas is one of the most popular choices for artists.
Watercolor paper is the most common and traditional carrier medium (the surface on which the paint is applied) for watercolors. Other supportive mediums for watercolor paintings include papyrus, bark, plastic, parchment, leather, fabric, wood, and watercolor canvas (coated with gesso specially developed for watercolors).
Other Specialties of Acrylic and Watercolor Paints
Acrylics can create effects that imitate watercolors and other water-based mediums when applied in thin layers or washes. Gel and molding paste are occasionally used to produce paintings with relief elements and can also create thick layers of paint. Acrylic colors used by professional artists are designed to resist chemical reactions from exposure to water, ultraviolet light, and oxidation. Although acrylic paints are non-toxic, they are not meant for direct application to the skin, as some pigments can be toxic and irritate the skin. Special face paints should be used instead.
Tube and pan watercolors are the two types of commercial watercolors available today. Most paints sold now come in typical, collapsible metal tubes and have a viscosity comparable to toothpaste. This paste must be diluted with water before use. Pan paint comes in two sizes: full pans and half pans. Watercolor paint is generally considered safe for skin contact. However, individuals with sensitive skin or allergies to certain chemicals may experience irritation or rashes. Always read the ingredients before purchasing watercolor paints if you have sensitive skin.
Toxicity and Vegan-Friendly Considerations
When used properly, acrylics are generally safe. They can be easily cleaned with soap and water since they are water-based and do not require hazardous cleaning agents. However, some acrylic paints contain ingredients like propylene glycol, which are harmful to the environment but not to people. Acrylics are suitable for vegans, except those containing ivory black PBk9.
Watercolor is generally safe as it often contains non-toxic pigments and binders. However, some binders used in watercolor paints are derived from animal proteins and fats, making some of them non-vegan.
Conclusion
In summary, both acrylic and watercolor paints offer unique artistic possibilities and benefits. Acrylic paints provide versatility, heat resistance, and the ability to mimic various painting styles. Watercolor paints offer transparency, shine, and a unique blurred effect when in contact with water. Each medium has specific properties, surfaces, and techniques that artists must consider to achieve their desired results. The choice between acrylic and watercolor paints depends on the artist's preferences and the effects they wish to achieve.
