recreation guide

Sandro Botticelli’s *The Temptation of Christ* (1482) is a significant example of Early Renaissance religious art executed in the buon fresco technique. This method involves applying water-mixed, alkaline-resistant pigments directly onto wet lime plaster, allowing the color to become chemically bonded to the wall surface through carbonatation (Source 1). Unlike oil painting, which allows for extensive blending and reworking, buon fresco demands rapid execution and precise planning, as the artist can only paint as much as can be completed in a single day, known as a *giornata* (Source 1). The durability of the work relies on the pigment sinking into the fresh plaster, forming a protective crystalline mesh known as the lime crust (Source 1).

estimated time

40-60 hours over 5-7 days (due to the strict daily drying limits of wet plaster)

6 in sequence

materials

item	purpose	modern equivalent
Hydrated lime (slaked lime)	Primary binder for the plaster layers (arriccio and intonaco)	Hydrated lime putty or quicklime slaked with water
Sand (fine and coarse)	Aggregate for the plaster layers; coarse for arriccio, fine for intonaco	Plasterer's sand
Alkaline-resistant pigments	Colorants that will not degrade in the high pH of wet lime	Earth pigments (ochres, umbers), ultramarine (if budget allows), lead white (with caution)
Water	Vehicle for grinding pigments and mixing plaster	Distilled or clean tap water
Charcoal or reddish-brown pigment	Transferring the design onto the dry undercoat (arriccio)	Charcoal sticks or terre verte
Long-haired brushes (avoided)	Not used; sources warn against them as they stick in lime	Stiff bristle brushes or flat wash brushes

preparation

surface prep

The wall must first be prepared with a rough, thick undercoat of plaster known as the *arriccio*, made of lime and sand, applied about an inch thick to create a rough surface (Source 1, Source 3). Once this layer is dry, the master painter’s composition is copied onto it using reddish-brown pigment or charcoal, allowing for necessary adjustments before the final plaster is applied (Source 1).

underdrawing

The design is transferred to the dry *arriccio* layer using charcoal or reddish-brown pigment. This allows the artist to make adjustments to the composition before committing to the wet plaster (Source 1).

underpainting

Buon fresco does not utilize traditional underpainting layers like oil painting. Instead, the pigment is applied directly to the wet *intonaco* (final plaster layer). The pigment mixes with the water in the plaster and sinks in, becoming part of the wall structure (Source 2).

color palette

Earth Tones (Ochres, Umbers)

Natural earth pigments ground in water

General use in this artist's palette; earth pigments are alkaline-resistant and suitable for fresco

White

Lead white or lime wash

Highlights and flesh tones; lime itself can be used as a binding medium to slow drying (Source 1)

Blue

Ultramarine or Azurite

Skies or drapery; large areas of sky can be painted rapidly (Source 1)

composition

Specific compositional details of *The Temptation of Christ* are not described in the provided sources. However, consistent with Renaissance practice, the composition would have been planned in sections (*giornate*) to accommodate the drying time of the plaster. Complex areas, such as faces, might take an entire day, while large areas like sky can be painted more rapidly (Source 1).

step by step

underdrawing→first pass→finishing→surfaceprep

underdrawing

step 02
Once the arriccio is dry, copy the composition onto it using charcoal or reddish-brown pigment. Make any necessary adjustments to the design.
Tip — This is the last chance to adjust the composition before wet plaster is applied.
Sinopia or cartoon transfer

first pass

step 03
Prepare the final thin layer of wet plaster (intonaco) only for the section that can be painted in one day (giornata).
Tip — Do not plaster more than you can paint in a single day.
Giornata
step 04
Wait until the intonaco is sufficiently set to bear the pressure of a finger without sinking, but still fresh.
Tip — Painting too early causes pigment to sink too deep; too late prevents chemical bonding.
Plaster setting
step 05
Apply pigments ground in water directly onto the wet plaster. Use stiff brushes; avoid long-haired brushes as they stick in the lime.
Tip — The pigment will sink into the intonaco, becoming part of the wall.
Buon fresco application

finishing

step 06
Allow the plaster to dry and react with air (carbonatation) to fix the pigment in a protective lime crust.
Tip — No re-touching is possible on buon fresco; mistakes must be chipped out and redone the next day.
Carbonatation

surfaceprep

step 01
Apply a rough, thick undercoat of lime and sand plaster (arriccio) to the wall, approximately one inch thick.
Tip — Ensure the surface is rough to provide a key for the next layer.
Arriccio application

critical techniques

Buon Fresco

Painting with pigment ground in water on wet lime plaster, allowing chemical bonding via carbonatation.

Giornata

Dividing the painting into daily sections based on the amount of plaster that can be applied and painted in one day.

Alkaline-Resistant Pigments

Using pigments that can withstand the high pH of wet lime without degrading.

common pitfalls

→Attempting to re-touch or correct mistakes on dry fresco; this is not possible in buon fresco and requires chipping out the plaster (Source 3).
→Using long-haired brushes, which tend to stick in the lime (Source 3).
→Painting on plaster that is too wet (pigment sinks too deep) or too dry (no chemical bonding) (Source 3).
→Plastering more area than can be painted in a single day, leading to uneven drying and loss of adhesion (Source 1).

what the sources don't tell us
