How to Recognize if a Vintage Painting is Made with Oil or Other Paints?

If you love antiques and vintage art, you've likely wondered: is this vintage painting done with oil paints or perhaps watercolor, gouache, or acrylic? Here are some simple tips on how to recognize a vintage oil painting and differentiate it from other techniques.

1. How to Recognize a Vintage Oil Painting by Texture and Relief

Oil paints often leave a distinctive, raised texture on vintage paintings. Look at the painting from the side: if you see brush marks and pronounced ridges, it's likely oil paint. Acrylics may have some texture, but they dry smoother and more evenly.

2. Observe Drying Time and Shine

Oil paints dry slowly, often leaving a shiny, luminous finish on vintage paintings. Older oil paintings may have developed a more uniform shine, sometimes with cracking (craquelure). Watercolor and gouache are matte and do not crack, as they're typically painted on paper.

3. Notice Richness and Depth of Colors

Oil paints are renowned for deep, rich colors. Colors are saturated and intense, and layered areas may appear especially deep and multidimensional. Watercolors and gouaches tend to be softer, more pastel, and translucent.

4. Identify the Painting Surface

Vintage oil paintings are typically painted on canvas or wood panels. Paintings on paper usually indicate watercolor or gouache. Acrylics are also frequently used on canvas but can appear on various surfaces, including cardboard or plastic.

5. Smell for Solvents (Fresh Paintings)

If you can examine a fresher vintage painting, gently smell it—oil paints use solvents such as turpentine or linseed oil, which have a distinct odor. Acrylic and watercolor paints usually have no scent or just a mild, neutral smell.

In summary:

• Raised textures, rich colors, gloss, and craquelure strongly indicate vintage oil paints.

• A smooth, matte finish suggests acrylic or watercolor.

• Painting surface (canvas vs. paper) also helps identify the technique used in vintage paintings.
