Camille Corot, 1860
recreation guide
This recreation guide addresses the technical execution of a fresco in the style of Camille Corot, specifically focusing on the *buon fresco* technique described in the sources. While Corot is historically renowned for his oil landscapes and studio-based figure paintings, this project requires adapting his characteristic aesthetic—restrained palette, poetic lyricism, and focus on tonal harmony—to the demanding medium of wet plaster. The artwork, titled 'Landscape with Three Figures' (1860), falls within Corot’s later period where his palette became more monochromatic and silvery, influenced by his interest in photography and a desire to avoid 'shocking' colors. The recreation must balance the rapid drying time of *buon fresco* with Corot’s methodical, controlled approach to composition.
estimated time
30-40 hours over 5-7 days (due to the strict daily deadlines of fresco giornate)

materials
| item | purpose | modern equivalent |
|---|---|---|
| Hydraulic lime or slaked lime (Ca(OH)2) | Primary binder for the plaster; undergoes carbonatation to fix pigments. | Hydraulic lime plaster mix (e.g., NHL 3.5) |
| Sand (silica) | Aggregate for the arriccio (undercoat) and intonaco (top coat). | Clean, sharp masonry sand |
| Alkaline-resistant pigments | Colorants that will not degrade in the high pH of wet lime. | Earth pigments (ochres, umbers, siennas), white lead (historical), or modern lightfast mineral pigments. |
| Water | Vehicle for pigments; no organic binder is required in buon fresco. | Distilled or clean tap water |
| Charcoal or red pigment (sinopia) | For transferring the design onto the arriccio underlayer. | Charcoal sticks or red ochre paint |
| Soot bag (spolvero) | For transferring pricked drawings via dusting. | Bag of charcoal dust or graphite powder |
| Trowels and floats | Applying and smoothing the arriccio and intonaco layers. | Standard masonry trowels |
| Natural hair brushes | Applying pigment to wet plaster; Corot’s controlled strokes require precise tools. | Hog bristle or sable brushes suitable for water-based media |
preparation
surface prep
Prepare a stable wall surface. Apply a rough, thick undercoat of plaster known as the *arriccio* to the entire area to be painted (Source 1, Source 2). Allow this layer to dry for several days. This layer provides the structural base and the surface for the initial design transfer.
underdrawing
Transfer the composition onto the dried *arriccio*. Historically, artists used a red pigment called *sinopia* or charcoal to sketch the composition on this underlayer (Source 1, Source 2). Alternatively, use the *spolvero* technique: prick lines on a paper drawing, hold it against the wall, and bang a bag of soot over it to create a dotted outline (Source 2). Adjust any necessary details at this stage before applying the final plaster.
underpainting
In *buon fresco*, there is no traditional oil underpainting. The pigment is applied directly to the wet *intonaco*. However, Corot’s early work involved a monochromatic underpainting or *ébauche* in oils (Source 6). For this fresco recreation, the 'underpainting' phase is effectively the first application of pigment into the wet plaster, establishing the tonal values immediately. Corot’s later style favored a restrained palette dominated by browns, blacks, and silvery greens (Source 6).
color palette
Pale Grey / Silver
White lime wash mixed with small amounts of black or dark earth tones
General atmospheric tone; Corot’s late palette was described as having 'leaden tones' and a 'single color, pale grey' (Source 8).
Dark Silvery Green
Green earth (Verdigris is not alkaline resistant; use Terre Verte or mixed earths) with white
Foliage and landscape elements; Corot’s palette was dominated by 'dark and silvery green' (Source 6).
Brown/Black
Raw Umber, Burnt Sienna, or Lamp Black
Shadows and structural definition; Corot used 'browns and blacks' which were 'forbidden colors' among later Impressionists (Source 6).
White
Pure lime plaster or white lead (historical)
Highlights and atmospheric haze; Corot focused on 'value of the tones' and 'harmony' rather than vivid color (Source 8).
composition
Corot’s compositions were 'well-thought out and generally rendered as simply and concisely as possible' to heighten poetic effect (Source 6). He often worked from studio sketches rather than direct plein-air completion for finished works (Source 6). The 'Three Figures' should be integrated into the landscape with a 'contemplative lyricism' (Source 8). Avoid sharp, shocking contrasts; instead, aim for the 'overall effect' and 'harmony of tones' that Corot prioritized (Source 8).
step by step
underdrawing
step 01
Sketch the composition on the dried arriccio using sinopia (red pigment) or charcoal. Alternatively, use the spolvero method with pricked paper and soot.
Tip — Ensure the design is accurate before applying the final plaster, as corrections are difficult.
Sinopia / Spolvero
first pass
step 02
Apply a thin, smooth layer of fine plaster (*intonaco*) to the section of the wall to be completed that day (*giornata*).
Tip — Only plaster as much as can be painted in one day. The size varies by complexity; faces may take a whole day, skies less (Source 1).
Giornata
step 03
Begin painting within one hour of applying the intonaco. Mix alkaline-resistant pigments with water only (no binder). Apply pigment to the wet plaster.
Tip — Work quickly. The plaster dries in 10-12 hours; ideal working time is 7-9 hours (Source 2).
Buon Fresco
refining
step 04
Use controlled, careful brushstrokes to establish tonal values. Corot’s strokes were 'controlled and careful' despite appearing spontaneous (Source 6). Focus on the 'value of the tones' rather than vivid color.
Tip — Avoid 'shocking' colors. Aim for the 'poetic' and 'monochromic' effect Corot sought in his later years (Source 8).
Tonal Modeling
step 05
If depth is needed, scrape indentations into the wet plaster to increase the illusion of depth, a technique used by Michelangelo and Raphael (Source 2).
Tip — This accentuates certain areas and creates shadow without pigment.
Plaster Scraping
finishing
step 06
Allow the plaster to dry and undergo carbonatation. The lime reacts with CO2 in the air to form a crystalline mesh (lime crust) that fixes the pigment.
Tip — Do not attempt to paint over dried intonaco with buon fresco technique. If mistakes are made, remove the intonaco or use fresco-secco (Source 2).
Carbonatation
step 07
If retouching is required after drying, use fresco-secco techniques (pigments mixed with lime water or organic binders) on the dry surface.
Tip — This is less durable but allows for longer working time and corrections (Source 4).
Fresco-Secco
critical techniques
Buon Fresco
Painting with water-mixed pigments on wet lime plaster. The pigment becomes part of the wall through carbonatation, ensuring durability (Source 1, Source 3).
Giornata
Dividing the work into daily sections based on the drying time of the plaster. This dictates the pace and planning of the fresco (Source 1, Source 2).
Tonal Restraint
Corot’s late style avoided vivid hues, favoring a 'single octave' of pale grey and silvery tones to achieve poetic harmony (Source 8).
