Bourdelle: Herakles and The Fruit / /

The first to be confirmed in both sculptures is that there patinas are affected. In the Heracles sculpture there are zones free of corrosion from some elements of assembling.

The restoring treatment consisted of cleaning both external and internal surfaces –in the case of Heracles- with high-pressurized water and comprised air. In the Heracles sculpture-assembling elements were changed (bolts, pegs, and nails) that were corroded. Then, heating was applied (122ºF) with the purpose of assure the total elimination of humidity and remaining signs of corrosion.

A first layer of protection with microcrystalline wax is applied and retouches of the clearer parts are performed with pigmented wax. Finally, a second wax layer is applied and a final gloss is given.

Mémorial Caen museum / / www.wikipedia.Caen

The Mémorial Caen collection gathers thousands of objects related with the daily life of civilian and military people from all warring countries during the Second World War. From there, the variety comes.

The year that we worked -2001 and 2002- the museum increases its surface by creating a new area mainly dedicated to the cultures of peace and Cold War.

Our job mainly was both the mechanic and chemical cleaning of each object and then takes inventory.

Auzon’s Gate


This gate, located in the commune of Auzon, is property of Saint-Laurent abbey (13th century). Despite it has never been restored, iron do not show any sign of active corrosion, but leather presents a really bad conservation state, moreover in its external part, where a thick layer of dust, grease, and other elements cover it. The wood, despite been rather damaged in the surface, looks well conserved.

Iron was mechanically cleaned, protecting metal with microcrystalline wax and final polishing. For the case of leather (external side) it was only possible to do it mechanically to conserve the quite fragile polychromic layer. To deliver flexibility, two layers of an emulsion that nourishes and rehydrates leather. In the internal side of the door, cleaning was made with mild soap for leather, and then the special wax was applied.

Regarding to fastening of leather with glue, the zones were first softened with small pieces of spongy, and then an acrylic-vinyl adhesive was applied.

Cannons of Invalides Army

www.wikipedia.Los inválidos

This restoring is made within the renovation project for the new presentation of a set of sixty cannons made of bronze, located in the honour yard of the museum.

The intervention consisted of cleaning with high-pressurized water, removal of filth layers and active corrosion placed through scalpel, flexible machine equipped with brushes, and metallic brushes. The object was heated to eliminate humidity and then it was waxed with microcrystalline wax, retouches with pigmented wax to get the set harmonized and finally it was polished


www.wikipedia.Catedral Langres  / www.catedral de

In the first visit it is confirmed that a big amount of treasure objects are infected by funguses, as long as the textile that cover the bottom of the glass cabinets. An amount of 150 objects to repair is estimated.

Restoring of metal objects includes a chemical treatment, applying of microcrystalline wax and final polishing. 

Reliquary of Saint Léger

www.Saint léger / www.Relicario Saint Léger 

The Saint Léger church shelters the homonym Reliquary whose structure, made of wood and covered by metal –silver and brass looks exalted by bronze overlays.

The reliquary is in a poor state of conservation, due to previous, makeshift interventions and to it is heavily soiled because of a recent fire.

A dismantling of decorating pieces will be performed, along with general, deep cleaning of the metallic surface with chemical products. After that, a protecting layer will be applied to metal with microcrystalline wax and final polishing. 

Blavignac Fount fuentes

The three elements that form part of the higher part of the fount show a big amount of deposit of carbonate that origin from water (tartar). The patina is quite altered and the set is in a poor state of conservation.

Restoring included mechanical cleaning with high-pressurized water that allows eliminating tartar in determined zones located at the centre of the pool, but is useless to clean other pool areas, as it a chemical treatment was chosen that will eliminate or transform the original patina, leaving metal with a reddish tone.

The creation of a new one is an operation made only in extreme cases that, for the case of the fountain was the best solution from both an aesthetic and conservation point of view. The protection of metal was made with microcrystalline wax and harmonization of the patina colour was searched through microcrystalline wax dyed with pigments. Final polishing was applied. 

Yarur Candelabrum


This object is property of Jorge Yarur, director and founder of Fashion Museum in Santiago, Chile, who entrusts me its restoring. The candelabrum is made of soft metal (pewter) in the zones that correspond to the bronze leaves and flowers, and it is made of silvered bronze the tube that supports the structure.

It is presented with a broke on its higher zone (where candles are put) so it was necessary, in order to keep its structure, manufacturing a piece (screw) of silver, which join both zones. A chemical cleaning for silver is performed, and the zones of the tube where silvered is lost are silver-plated. Then microcrystalline wax is applied and it is polished. 

Yarur lanterns

Four lanterns made of copper and bronze, located outside the house, designed in the 50s for his summerhouse in Reñaca. First, dust was eliminated with brushes, and then every element was disassembled. It was necessary to cut the screws that join the protection bars of the glass globe, as they was molten due to corrosion formed over the years. The object was left one month in a bath of distilled water. Every week the water was changed, with the aim of remove the salt in the metal, which is the main corrosion factor. After that, the filth remains are eliminated with scalpel, brush and flexible. It was necessary to manufacture a piece of copper to cover the lowest part of the lantern, due to a strong corrosion that generated loss of metal in this area. This piece is adapted to the base and stay fix by pressure and, as it is movable in the future it will allow to be changed if necessary.

Applying of microcrystalline wax, manufacturing of sacrificial anodes, whose aim is slowing down the corrosion of metal, in the base of the object, as there humidity and rain water is deposited. Polishing and for a bigger surface protection, varnish is applied. An annual maintenance is recommended, due to outdoors and environment salinity.

Chartres Cathedral de Chartres

The intervention consisted of: cleaning, taking photography, making inventories, and then sorting plaster casts sculptures from the cathedral, much important in case of losing structures that are in the highest area of the Chartres Cathedral.

Cross-from 13th century

This is a cross in poor state of conservation. It was necessary disassemble it and keep out its wood core in order to join its parts that was destroyed. Then, it was necessary to create a patina as much like as the original one. Unfortunately, I do not have the last picture in which Virgin and Christ are joined to the cross. 


www.matanza Oradour /

Due to the features of this place, and of that cars are outdoor, solutions are taken that allow slowing down the inevitable degradation of the cars.

Because of this, a manual cleaning is set with planes, brushes, fibreglass, scalpel, and abrasives; with the purpose of eliminate the corrosion products on the metal surface.

Microcrystalline wax was applied after heating metal (three layers). Then it is polished and isolated from the ground by platforms and guards.

Maintaining is recommended here. 

George Sand Castle


The collection is comprised by a set of objects, which are in the attic from 1999. It is in total disorder and counts on accessories, suits, hats, furniture, ornaments, little decoration stuff, and theatre furniture.

My job in this big operation consisted of mechanical cleaning with a soft broom, vacuum, and micro vacuum in the case of fragile, filthiest objects through sticks covered with cotton and soaked with solvent or soapy water, and then a thorough rinsing. Also, there are eventual consolidations and fixed, then there is photography and detailed account.

Rooms final restoration

Henri IV Boxes / www.revue.Henri

Six boxes in which it was necessary to disinfect the wood, with an antifungal treatment and post consolidation with Paraloide resin.

The cleaning of the lead leaves was chemical. It was shaped again due to its forced opening. Finally, to maintain the structure, shapes with PLASTAZOTE foam in within. 


Valloires Abbey

www.wikipedia.Abadia Valloires /

Bars located in the centre of the Chapel, from the second half of the 13th century in forged iron and re-annealed sheet.

Multiple points of corrosion are observed in the lower part of the bars. There are several decorative elements that have been deformed or disappeared. Painting is in poor state and gilding is altered due to its contact with the audience.

Corroded areas were mechanically treated with micro-brooms, brooms, heat guns, scalpel and passivation of corrosion by chemical bias. Deformed decoration elements were repaired and there the missing pieces were replaced.

The old painting is eliminated with: heat gun, broom, and scalpel. The surface is prepared by putting a layer of antirust to then apply asphalt-based paint (previous paint.)

Decorating elements are gilded with a sheet of “fine gold leafs”, with the technique known as “size” or “mordant”.

Mosque-El Cairo, Egypt

Chinese plaques

Restoring for an individual in Paris. It is in poor state of conservation, with remarked signs of active corrosion and in some zones with loss of metal.

As it for its delicate state, it is chosen a minimum intervention. The mechanic elimination of corrosion is performed with fine broom and scalpel; then two layers of microcrystalline wax and final polishing.

Notre-Dame Cathedral


Restoring made here are inside the project of a new presentation of the treasure of Notre-Dame Cathedral, in Paris.


Vinegar and oil cruet in their own dish

Work of Maurice Poussielgue-Rusand, goldsmith (1861-1933). The dish is made of golden copper with four enamelled medallions. Cruets are made of glass and golden copper.

Restoring process consisted of stripping down and stuck of glass of one of the pitchers and the manufacturing of two screws locate in the higher and lower area of both jugs, allowing to stuck the metallic part to the pitcher, keeping the top in its place. Cleaning of both jugs and of the dish was made through soft polishing. 

Christ on the cross of Carpeaux

www.wikipedia.Carpeux  / www.Carpeaux

Christ on the cross, 19th century, made from plaster with base and cross of wood. Its left hand is broken in the fist with presence of old glue, the same as the right hand.

Cleaning is carefully made with gum dust and sticks covered with cotton and soaked with water, along an active tense are used here. Fists are stick with adhesive acrylic reversible. Wood was applied with microcrystalline wax, polishing and mounting.  


The Virgin and the boy


Sculpture in silver, it is located in the Treasure of the Notre Dame Cathedral. This sculpture shows old remains of cleaning products and minor blackening of the silver.

Cleaning of silver is performed with rags and special products. The product is carefully eliminated with rags coated with distilled water. After that, two layers of microcrystalline wax are applied and finally it is polished. 

Reliquary of the Holy Crown of Thorns

Manufactured in gold, vermeil –for background, quartz crystal, diamonds, fine pearls, sapphires, amethysts, rubies, garnets, turquoises, opals, 1896. Outside measure: 11.220in. Inside diameter: 7.2835in.

The intervention consisted of some metallic parts that act as lock system, keeping the crystal that protects the Crown of Thorns united. Crystal and metal were cleaned and a soft polish was made. 

Bars of Noyon Cathedral

Classified on 1923 as Historical Monument, these elements probably date from 20th century’s second half.

The elements kept were roughly reunited in a presentation in semicircle and mounted high on the wall, in which ten different elements are stand out.

Despite of being warm, this fork iron bars show a hard corrosion in several places.

Restoring intervention considers the dismantling and replacement of elements. Mechanic treatment of cleaning, protection of metallic surface with microcrystalline wax (two layers) and reassembly proposal was performed. 

Table grape museum, Thomery

There is exhibited a series of objects related to production and collection of grapes. It’s restoring depended on the kind of material and state of conservation of the object.
