Studio Craft: Oil Paint

1. Paint has been made out of human remains.

True

False

Mummy Brown (sometimes called Caput Mortuum) was once made from real mummies. Real mummy pigment is no more- thank goodness! http://www.time.com/time/magazine/article/0,9171,940544,00.html

2. Pure oil paint straight from the tube dries through:

Oxidation

Evaporation

The drying oils used to make oil colors solidify by taking up oxygen.

Explanation

The drying oils used to make oil colors solidify by taking up oxygen.

3. "Tint Strength" of a color is best described as:

The thickness of the paint

Degree of color change a paint causes when mixed with a standard white

The amount of paint it takes to cover a standard white

The amount of pigment it takes to make a color

Tint Strength is a measure of the power of a color in mixtures. Colors with high tint strength produce more color change (tint more powerfully) in a measured amount of white paint than those with low tint strength.

4. Linseed oil comes from the same plant as linen fabric.

True

False

Linseed oil is pressed from flax seed which is derived from the flax plant, the source of flax fiber for linen cloth.

5. Distributing pigment throughout the oil paint vehicle by milling or hand-mulling is also called:

Emulsion

Dispersion

Saponification

Wetting

Paint is made by dispersing pigment in a vehicle.

Explanation

Paint is made by dispersing pigment in a vehicle.

6. Traditional tube oil paints give off flammable vapors.

True

False

The oil paint vehicle is a vegetable oil; tube oils alone do not produce flammable vapors.

Explanation

The oil paint vehicle is a vegetable oil; tube oils alone do not produce flammable vapors.

7. Which of the following is NOT a category of pigment?

Natural Synthetic

Synthetic Organic

Natural Organic

Natural Inorganic

Synthetic Inorganic

Pigments are either natural or synthetic; they can't be both!

Explanation

Pigments are either natural or synthetic; they can't be both!

8. Adding beeswax to oil paint produces:

A short bodied mixture

A long bodied mixture

Oil emulsion

Tempera

The addition of wax creates a "short" paint- in other words, the paint does not produce long strings when pulled with the palette knife.

9. The least lightfast pigment still considered suitable for the permanent palette is:

Hansa Yellow

Ultramarine Blue

Viridian

Alizarin Crimson

Alizarin Crimson is more susceptible to color change from light exposure than other colors in the modern palette.

Explanation

Alizarin Crimson is more susceptible to color change from light exposure than other colors in the modern palette.

10. When Alizarin Crimson is mixed with white, the resulting mixture is more lightfast.

True

False

Mixing a fugitive color with white exposes pigment particles to more reflected light from within the paint film, resulting in faster color change.

Explanation

Mixing a fugitive color with white exposes pigment particles to more reflected light from within the paint film, resulting in faster color change.

11. Which of the following pigments is actually a type of glass or ceramic?

Crystal violet

Smalt

Smelt

Glassine

Smalt is the correct answer because it is a pigment that is made from powdered blue glass or cobalt glass. It is a type of glass or ceramic pigment that is commonly used in the creation of blue paints and dyes. Crystal violet is a synthetic dye, smelt is a type of fish, and glassine is a smooth and glossy paper, none of which are related to glass or ceramic pigments.

12. Cadmium Red is an example of which type of pigment?

Synthetic organic

Natural inorganic

Natural metallic

Synthetic inorganic

Cadmium Red is a synthetic inorganic pigment because it is produced through chemical processes and does not occur naturally. Inorganic pigments are typically derived from minerals or synthetic compounds, and they offer a wide range of vibrant and stable colors. Cadmium Red, in particular, is made from cadmium sulfide, a synthetic compound that provides a bright red hue.
