Élisabeth Vigée Le Brun

Peter Koneczny restores and conserves Gothic paintings and sculptures, Old Master paintings, 19th century and Modern and Contemporary paintings.

- Technical examination, assessment of condition and determining appropriate treatment.
- Structural repairs of painting supports such as canvas, panels, painting boards, copper, etc.
- Stretcher repairs.
- Mending tears and holes in the canvas.
- Relining.
- Strip lining of the brittle tacking edges of canvas.
- Impregnation of fragile, oxidised canvas with polymers.
- Treatment of flaking paint.
- Cleaning and removal of yellowed varnish.
- Removal of old overpaint.
- Filling and retouching paint losses.
- Varnishing.
- Impregnation of damaged wood and insecticide treatment of wooden sculptures.
- Photographic documentation of the conservation - restoration process.

In the delicate process of cleaning dirt from the surface of paintings and the removal of yellowed varnish and overpaint Peter applies his extensive knowledge of chemistry and art materials in tailoring cleaning methods for each individual painting.

This approach is particularly effective in cleaning paintings where the artist has experimented with unconventional painting media, as in the case of Thomas Gainsborough who mixed water soluble media with solvent soluble resins for glazes.

Removal of extremely discoloured varnish from 18th century landscape.

The retouching of paint losses is carried out using dry pigments mixed with light fast, non-ageing synthetic resins which are easy to remove with mild solvents.

When retouching Peter has available an extensive range of over 1600 pigments used in art throughout the ages, which include classical pigments hand made by methods described in old manuscripts. He also has in his collection some original pigments made by George Field (1777?–1854).

B72 Retouching Gels, invented and patented by Peter, which are used in museums and conservation studios throughout the world enable him to imitate almost any painting technique.  By mimicking the properties of the paint used originally by the artist they allow the restorer to paint wet-on-wet, painting textures and impastos, and panting glazes and imitating the texture and transparency of megilp.

In the case of a pair of topographical paintings of Malta extensive historical research had to be undertaken in order to accurately reconstruct buildings and details missing in the damaged areas of the paintings. Historically correct reconstruction, for the time in which the paintings were painted, was based on the detailed analysis of many etchings, sketches, paintings and street plans.
