Transparent and Reflective Surfaces

The look of glass, plastic, metallic or glazed surfaces can be achieved in a drawing through careful observation and meticulous recording.

Identify the different areas of value, their shape and location in relation to the perimeters of the object and each other, as well as the hardness or softness of their edges. Think about drawing a topographical map, recording each shift in terrain, the terrain being value. Lightly outline each area of value on the surface and then apply those values.

Try not to make your drawn object "look" like glass or chrome or any other transparent or reflective surface. Instead, focus on accurate form and careful observations and placement of information, and the materiality of your subject will come through.
