ICI Delhi offers a wide variety of professional conservation and preservation services to various governmental and non-governmental organizations, private collectors and corporate clients. Objects requiring varying levels of study, evaluation as well as treatment can be brought to the Centre. A dedicated team of conservators represent years of varied professional training at major institutions, both in India and abroad, specialized study, and intensive practical experience in the science of conservation and study of objects may be requested. The conservation staff can facilitate scientific study and analysis of objects.
Examination under UV light
Examination under ultraviolet light is applied to assess the nature and condition of the varnish and restoration layers lying on the surface of the painting. Under this short wavelength light materials fluoresce and phosphoresce depending on their properties. The differences in the age and chemical composition of painting media and surface coatings (varnish layer) can be detected by the difference in fluorescence
Painting (left) under UV right (right) showing different fluorescence. The aged layers are greenish yellow in colour while later additions appear purplish in colour.
Infrared reflectography involves examination using the longer wavelength infrared radiations where a special infrared camera captures the light reflected off the surface of the painting. As these rays penetrate through the layers of painting, layers of painting otherwise not visible to naked eye such as underdrawings and changes in painting are revealed.

• Preventive measures
• Documentation and examination with Infra red and Ultra violet photography
• Anti fungal and insecticidal treatment
• Mechanical cleaning
• Solvent cleaning
• Consolidation of paint layer and support
• Reinforcement of objects
• Stretching and framing
• Display methods
Oil painting: Before and after conservation
Conservation of paper objects
Paper objects are exposed to many problems such as tear and losses, grime and accretions, foxing, discolouration, yellowing of paper due to acidification, waviness and creases, unscientific mending with adhesives and tapes and partial or complete colour losses.
Services we offer
Paper object: Before and after conservation
Conservation of textiles
Textile objects are exposed to many problems such as tear and losses, grime and accretions, fading and darkening, stains, yellowing due to acidification, waviness and creases, adhesives and tapes and partial or complete colour losses, etc.
Services we offer
Conservation of 3-D objects (metal, wood, stone, ceramics, etc.)
Some of the major problems encountered in these objects are surface accumulation, cracks, discoloration, losses, powdering and flaking, dismembering and breaking into pieces, dents and bulges, abrasions and scratches, efflorescence, detachment, deformation etc.
On-site conservation: The ICI Centres undertake conservation of collections on site by setting temporary laboratories. Projects involving in-situ conservation and preservation of stone and decorative features of monumental architecture that include wall paintings, stucco and plaster finishes, mosaics, tiles, cast stone, terracotta, relief work, decorated wooden elements, decorative glass, gilding and other embellishments are also undertaken.
Consultation: Conservators can also offer advice and solutions to issues related to care and upkeep, storage, proper display, exhibition and safe transportation.
Projects related to conservation and researches are also undertaken in collaboration with other institutions and organizations.
