Drawing glass can present a unique set of challenges to an artist. With glass, the artist must consider transparency and reflection. For many beginning artists, creating these illusions can be quite puzzling. Throw in a medium like oil pastels, and the challenge can seem downright overwhelming.
However, if we approach drawing glass in the same manner that we approach drawing anything else, the challenge becomes a lot less daunting.
Remember, drawing is about observation. But it's also about knowing what to observe. In this case, we need to pay close attention to relationships of dark and light values and the shapes that they make on the subject.
In most circumstances, an area that is reflective will feature strong contrast between light and dark values. These light and dark values are often right beside each other.
Transparency can often be depicted in a scene through distortion and manipulation of the intensity of the color.

The finished result, using the approach demonstrated in the video, has the appearance of a painting. The colors have been layered heavily producing a physical texture on the surface. The goal was to create a "loose" drawing that still communicated the transparency of the glass.
Oil pastels are a unique drawing/painting medium that allow the artist to build up rich colors in short amount of time. When used to their potential, they can produce images that are rich and vibrant in color and appear to be "painted".
Not to be confused with soft or chalk pastels, oil pastels feature an oil-based binder. This makes them suitable for use with traditional solvents used with oil painting.
