We just have 2 more class sessions in our study of glass. This is a pretty terse 16"x12" and I am painting on my favorite ground - a scraped down canvas; the remains of maybe 10 scraped off paintings. It is the only way to give the canvas that wonderful crapped out look; almost a shame to cover it up.
Our little green apple makes an appearance but only as a subordinate; having an item BEHIND the glass object helps show clarity, especially if the background is ambiguous.
Though it has nothing to do with glass, I would note the brushes inside of the mug. It seems obvious that they would have to rest on the rim and as well, go to the bottom; sometimes this is lost on the beginner (or some of us who can't make our brushes straight). Any straight item, be it a brush, pencil, stick, flower stem cannot stand on its own but must rest on the rim and (allowing for a bit of glass distortion) must also follow a straight path all the way to the bottom of the container. So check that angle in the drawing before heading to paint.

For the next few weeks in class we will be taking time to focus on glass. First, clear glass, that being the simplest. I love to paint glass and take a less-is-more approach that allows the eye of the viewer to fill in the blanks. The clear bottle at the top is only visible because of its highlights and that's the key to clear glass - it has to be clear. Shading on the inside, darker or lighter, makes the glass look dirty or even take on the appearance of something that is ceramic. Add a strong highlight and it will look shiney but it won't be clear glass. The painting below deals with colored glass; more about that later.
