Paint Cut Glass in Watercolor
Transparent objects, such as cut glass, are among the most difficult to render in watercolor. Painting them correctly requires careful observation and planning. The nature of watercolor paints doesn't allow erasing or covering mistakes. The process of painting cut glass can be broken down into a few simple steps. Work slowly and carefully, and you'll be able to render beautiful glass in watercolor media.
Instructions
1. Draw the cut glass. Use light pencil strokes to render an accurate line drawing of the crystal object you wish to paint. Don't press hard, or you'll risk the drawing showing through in the finished painting. You can also use an opaque projector to project a photograph of cut glass onto your paper, then trace the lines. Remember to include the reflections, as well as the shape of the glass itself.
2. Examine the colors. Clear cut glass has no color of its own. All the colors in your painting will come from reflected light bouncing off other objects in the image. Even colored cut glass will acquire some color from nearby objects. Choose which watercolors to use based on the colors of the reflections you see. Plan out what you'll paint before you touch brush to paper.
3. Create washes. Add water to your colors to create thin solutions. Don't use colors at full strength - they can overpower your image.
4. Begin painting. Use very dilute washes to lay in the lightest colors in the glass. Leave plenty of white spaces to preserve a bright look. Use smooth patches of color to represent reflections in the facets of the glass. Keep your plan in mind as you paint.
5. Add stronger washes. Once you've laid the lightest colors into your painting, you can strengthen some areas with less dilute paint. Be careful not to overdo it - start with very small areas in the shadows, and check against your subject frequently. Continue darkening small areas until you have produced the desired effect. Allow the painting to dry completely before framing.
