Chapter 11 Glass

Objectives (1 of 2) Understand and explain the unique properties of glass as a still-life subject. Draw clear glass objects accurately by rendering their shape and interior reflections, any objects seen through the glass, and any objects reflected in the glass.

Objectives (2 of 2) Draw colored glass objects with their proper local color and the shading that gives them volume. Draw clear and opaque or translucent liquids held in a glass object, accurately rendering the way such liquids transmit or reflect surrounding objects.

Drawing Clear Glass First, draw the shape of the glass object. The outside, inside, and lip of the glass have their own light, shadow, and highlight areas.

Seeing through Glass Curved glass distorts whatever is seen through it. –More curvature = greater distortion Designs (like the stem) distort even more. There are also reflections in glass.

Colored Glass Lay down a light tone for the local color of the glass object, leaving the highlight white. Anything seen through the glass will appear darker than it is.

Transparent Liquids in Glass Water has its own volume, form, highlights, and shadows. Water distorts and magnifies what is seen through it.

Opaque Liquids in Glass Opaque liquids behave more like solid forms than like water. Most opaque liquids are at least partly translucent. Lay down a light tone for the local color of the liquid.

Summary (1 of 2) In a transparent object, you can see its interior surface, objects placed behind it, and reflections on its surface. Begin every drawing of a glass object by drawing its basic shape. Curved glass surfaces distort the objects you see through them.

Summary (2 of 2) Clear liquids magnify and distort objects seen through them. For colored glass or colored liquid in a glass object, put a tone over the whole area to represent the local color. Opaque liquids act almost like solid objects, but may transmit some light.
