1Which dry drawing medium is produced by the slow, oxygen-deprived carbonization (calcination) of thin willow or vine twigs?
A.Vine charcoal (carbón vegetal)
B.Sanguine crayon
C.Graphite pencil
D.Oil pastel
Explanation: Vine charcoal (carbón vegetal de sauce o vid) is made by heating natural wooden twigs in sealed containers without oxygen, producing a velvety, soft, easily blendable carbon drawing material.
2In the standard graphite pencil hardness grading scale, what does a higher number preceding the letter 'B' (e.g., 6B vs. 2B) indicate?
A.Higher proportion of graphite relative to clay, resulting in softer, darker marks
B.Higher proportion of clay relative to graphite, producing harder, lighter marks
C.Greater concentration of wax binders to make the lead waterproof
D.Higher resistance to smudging and mechanical abrasion
Explanation: Pencils marked 'B' (Blackness) contain a higher ratio of graphite to clay binder; as the number increases (e.g., 6B), the lead becomes softer and leaves darker, broader carbon deposits.
3Which traditional drawing medium features a rich terracotta reddish-brown hue derived naturally from anhydrous iron oxide (hematite)?
A.Sanguine (sanguina)
B.Sepia
C.Bistre
D.Plumbago
Explanation: Sanguine takes its name from blood ('sanguis') due to its warm reddish-brown iron oxide color, widely used during the Renaissance by artists like Leonardo da Vinci and Michelangelo.
4What is the primary function of a paper stump (difumino / tortillon) in dry media drawing?
A.Blending and softening hard lines into smooth tonal gradients by smudging pigment particles
B.Lifting highlights by erasing pigment down to the bare paper surface
C.Applying a protective seal to prevent charcoal from smudging
D.Sharpening the tips of soft pastel sticks without crumbling
Explanation: A difumino (paper stump) is a tightly rolled cylinder of paper used to blend, smear, and smooth dry particles of charcoal, graphite, or chalk to produce seamless tonal transitions.
5Why must liquid fixative (fijador) be applied in light aerosol sprays over un-fixed charcoal or pastel drawings?
A.To bind loose pigment particles to the paper fibers using a thin film of resin or shellac
B.To dissolve the pigment particles into a permanent waterproof acrylic paint layer
C.To bleach yellowed paper background back to pure white
D.To increase the surface gloss of matte pastel strokes
Explanation: Fixatives spray a fine mist of natural shellac or synthetic resin dissolved in alcohol, which coats loose charcoal/pastel dust and binds it to paper fibers to prevent accidental smudging.
6What is the key pigment and binder composition of authentic waterproof Indian Ink (tinta china)?
A.Fine carbon soot (hollín) bound with shellac or gelatin in water
B.Iron gallate crystals dissolved in sulfuric acid and water
C.Synthetic phthalocyanine dye mixed with linseed oil
D.Crushed walnut shells boiled with gum arabic
Explanation: Authentic Indian ink consists of microscopic carbon black particles (lampblack/soot) suspended in water with an alkaline shellac or gelatin binder that becomes completely water-insoluble once dry.
7Why does metalpoint drawing (e.g., silverpoint / punta de plata) require a specially prepared abrasive ground (gesso or bone ash priming) on the paper?
A.Because soft metal styluses cannot leave marks on smooth, unprimed paper without abrasive tooth
B.To prevent the silver wire from melting due to friction during rapid strokes
C.Because silver wire oxidizes immediately into pure liquid ink upon contact with raw cellulose
D.To allow lines to be easily wiped away with a wet damp sponge
Explanation: Silver wire is too hard to leave a streak on bare, smooth paper; the support must be primed with an abrasive ground (such as bone ash or zinc white in glue size) whose microscopic tooth shears tiny particles of metal from the stylus.
8What chemical change causes silverpoint drawing marks to shift color over time from initial cool grey to a warm golden-brown patina?
A.Oxidation and reaction with atmospheric sulfur forming silver sulfide ($Ag_2S$)
B.Evaporation of volatile essential oil binders contained inside the silver stylus
C.Photodegradation of the organic bone ash pigment in the priming
D.Absorption of moisture converting metallic silver into iron rust
Explanation: Microscopic silver particles deposited on the ground react slowly with atmospheric hydrogen sulfide and oxygen, tarnishing into silver sulfide ($Ag_2S$), which gives aged silverpoint drawings their warm brownish tone.
9Which historic brown ink was prepared by boiling beechwood soot (hollín de haya) in water and extracting its water-soluble tarry pigments?
A.Bistre
B.Sepia
C.Iron gall ink
D.Prussian blue wash
Explanation: Bistre is a yellowish-brown ink made by boiling wood soot (specifically beechwood soot containing tar and resinous materials) in water, widely used for monochromatic wash drawings from the 14th to 18th centuries.
10What major conservation hazard is associated with historical iron gall ink (tinta de agallas de roble) on paper manuscripts?
A.Acidic ink corrosion caused by excess sulfuric acid and free iron ions destroying cellulose fibers
B.Instant flaking of ink due to complete lack of adhesion to paper
C.Rapid fading to total transparency within five years of exposure to room light
D.Severe fungal infestation driven by high sugar content in oak galls
Explanation: Iron gall ink contains excess iron(II) sulfate and free acid; over time, iron ions catalyze oxidation (Fenton reaction) while sulfuric acid hydrolyzes cellulose, causing paper embrittlement and burn-through (corrosión por tinta).

La Rioja PAU Graphic-Plastic Expression (UR): Suggested Study Strategy

1Understand the chemical and physical differences between drying oils (linseed, walnut) and water-based binders (gum arabic, egg yolk, acrylic polymer emulsion).
2Memorize the fundamental rule of oil painting: 'fat over lean' (graso sobre magro) to prevent cracking during drying.
3Distinguish clearly between relief printing (woodcut, linocut) where raised areas receive ink, and intaglio/calcography (etching, aquatint, drypoint) where ink resides in incised grooves.
4Master color theory principles, including additive (RGB) vs subtractive (CMYK) color mixing, Chevreul's law of simultaneous contrast, and optical color blending.
5Review conservation ethics: reversibility of restoration treatments, minimal intervention, and distinction between original material and restored areas.

Frequently Asked Questions

Is this practice bank in the same format as the real La Rioja PAU exam?

No, and it is important to know the difference. The official La Rioja PAU paper is a 90-minute examination sat in Spanish containing open, semi-constructed, and practical graphic expression questions. Under the 2026 PAU design rules agreed by UR and CRUE, open and semi-constructed responses must account for at least 70% of every paper, so the real exam contains no multiple-choice section. This bank is an English-language multiple-choice study adaptation of the same official 2º Bachillerato syllabus — not an official translation, not a past paper, and not a simulation of the exam format. Use it to drill technical concepts, material chemistry, and procedural knowledge quickly, then practise executing technical drawings, color exercises, and written responses under timed conditions separately.

What is the format of the La Rioja PAU Graphic-Plastic Expression Techniques exam?

The exam is a 90-minute written and practical assessment evaluating students on artistic techniques, chemical properties of media, printmaking methodologies, color theory application, and artwork conservation concepts.

What passing score is required for university admission?

The exam is marked on a 0–10 scale. A minimum grade of 4.0 is required in the Access Phase to calculate the overall university entrance mark (60% Bachillerato GPA + 40% PAU Access Phase >= 5.0).

What registration fees apply for PAU in La Rioja?

The base registration fee for the PAU Access Phase set by Universidad de La Rioja / Gobierno de La Rioja is EUR 55.43.

What key media are tested in the exam?

The syllabus covers dry drawing tools (charcoal, graphite, sanguina, pastels), wet drawing (Indian ink, washes), painting techniques (watercolor, tempera, acrylics, oil, fresco, encaustic), printmaking (xilography, linocut, etching, aquatint, lithography, screen printing), and support preparation.

Are conservation and restoration principles included on the PAU exam?

Yes. Basic concepts of preventive conservation (relative humidity, light damage, atmospheric pollutants), restoration ethics (reversibility, minimal intervention, legibility), and deterioration phenomena (craquelure, foxing) are explicitly part of the 2º Bachillerato curriculum.
