Glass Bowl with Limes in Light and Shadow

Some subjects I paint over and over.  I love the translucency of glass bowls.  How do you paint glass?
You paint what's behind the glass, or what's in the glass first.  Then create the shape of the glass bowl by wiping out lights, especially along the rim and foot, and then add shadows and reflections. Last come highlights and bright whites. 

Blood Orange Slices

These blood oranges have a brownish red color.  Not as pink as a ruby red grapefruit.  The entire tabletop was white, but I dropped the value lower so that I would have enough contrast to paint the light struck areas.
