Painting the image of glass is something beginning painters avoid.

Why would you want to avoid painting glass? Hmm, let’s see. First you need to capture the background which is showing through the glass. Next, you have stems and leaves that show through. Third there is refraction going on, so the stems might appear bent or not where you expect them. Next you need to capture liquid. Is the glass half-full or empty? Finally, you need to paint the glass itself and the reflections that bounce off of it.

So yes.  There is quite a bit involved.

I came to watercolor class with everything else painted and ready to go.  I also sketched in some very simple guide-lines.

The two glass bottles in this painting were done using two different techniques.  why?  So I could show my class there are two ways to tackle the problem.  I wouldn’t normally do this in a painting, but it does help to show.  The left bottle was done with dry-glazing techniques. Meaning I used many layers of light watercolor wash.  You use very little water so as to have more control.   The bottle to the right was painted using the wet-on-wet technique.  I painted the entire bottle with clear water and then dropped paint into the water which makes it spread where ever there is water.  The glazing technique gives you a more precise look and the wet-on-wet is generally softer and more flowing.

Now I’ll tell you the secret to painting glass in watercolor no matter which technique you use.

There is no white paint in watercolor.  You use the white of the paper.  So if you want a white area, don’t put any paint there.  However, there is another technique you can use to create white areas.  The technique is called lifting.  Lifting is when you take a clean paintbrush, dip it in water, take the access water off so it is damp and then you rub the paint away in a particular area.  Watercolor is not permanent.  You can’t dry it and it’s there forever.  In some ways that’s bad, but in some ways it’s good.  By simply wetting your painting you can pull up or “lift” the paint off the paper.  Now look at the photo above.  See all the different places where I am simulating reflection by creating light areas.  I rubbed, scrubbed and wet those areas until the paint lifted.

The rest is observation and practice, which for most of us takes a life-time.  With that said, there’s no time like the present.  Let’s get practicing!
