A close view shows a dense, deep black band that smears under a fingertip and is hard to erase completely. Which medium made it?

The pictured fine gray strokes are even, narrow, and slightly shiny when light strikes the paper at an angle. Which drawing medium most likely made them?

A loosely held stick leaves a pale, powdery mark that erases readily during a preliminary sketch. What is the medium?

A 16th-century drawing has rust-red strokes that form both narrow hatches and broad rubbed passages. Which material is most likely responsible?

Broad gray passages fade transparently into the white paper, while darker contours remain visible beneath them. Which medium produced this effect?

The image shows intensely colored, matte powder resting on the paper surface in layered strokes. Which drawing medium is it?

A drawing's fine gray lines have slowly turned warm brown over centuries because the metal deposited on the paper tarnished. Which medium made them?

A studio handout says the colored stick will not hold well on slick paper; the support needs slight tooth to grip its crumbly material. Which medium is described?

A finished sheet needs a lightly textured support and a fixative because loose dark particles could otherwise rub away. Which medium is being used?

For a sketch that will need repeated corrections, an artist chooses a pointed material whose marks can be lifted with an eraser from the support. What should the artist use?

An artist wants red, black, or white mineral sticks that can be used without a prepared ground or complicated tool. Which material fits this description?

A technical illustrator needs a smooth, hard-sized sheet so a pointed nib can make uninterrupted, crisp lines without catching in the paper fibers. Which medium best fits?

Why are finished soft-pastel drawings especially vulnerable to damage during handling?

Graphite pencils are graded from hard H pencils to soft B pencils. Compared with a hard pencil, what does a soft B pencil produce?

An artist turns a charcoal stick sideways and then rubs its particles with a finger. What effect does this working method encourage?

Why is silverpoint less suited than charcoal for deep, velvety shadows?

What happens when drawing ink is diluted with more water before it is brushed onto paper?

A dark area is built from closely spaced parallel strokes all running in one direction. What drawing technique is this?

An artist layers one set of parallel pen lines over another set running at an angle. What is this shading technique called?

A shaded cheek is constructed from many tiny, separate dots rather than lines or rubbed powder. Which technique is being used?

Rather than adding marks, an artist uses a rolled paper tool to blend existing charcoal particles into a soft gray transition. What is this technique?

A brush carries diluted ink across a sheet in broad, semitransparent passages. What technique is being used?

An illustrator plans each line carefully because, once dry, these solid black marks cannot be erased from the paper. Which medium is being used?

A designer needs one dry medium that can make fine outlines, broad shadows, and erased highlights while planning a composition. Which medium is the best choice?

An artist wants delicate, precise linear drawing with a metal stylus and is willing to prepare the paper first. Which medium best meets that requirement?
