Close inspection and recording of the paintings have been the first step to understanding their original technology and condition.
Computer documentation has been used to record the condition of the paintings and to help understand the distribution and potential mechanisms of deterioration.
Original painting technology
Knowledge of the original technology of a wall painting is central to understanding its current condition. Pentimenti are common in the paintings of Hadi Rani Mahal, often ‘erased’ with a semi-opaque paint layer, as here. The bird’s head has been tilted up more than in the original configuration.

Monitoring structural movement
Measuring crack monitors has been routinely carried out to assess structural movement in specific areas of the Hadi Rani Mahal and the Sheesh Mahal.

In-situ microscopy of a gilded detail in the Hadi Rani Mahal's second-floor vaulted chamber. In-situ microscopy provides information on original technology and deterioration phenomena.
In-situ microscopy and FTIR-ATR analysis was carried out to assess the original and added materials and to develop appropriate intervention techniques.
Visible and multispectral imaging (MSI)
Inspection of the wall paintings in UV light allows for a better understanding of both the original technology and the current state of condition. The top image was taken in the vault of the Hadi Rani Mahal's second-floor vaulted chamber using visible light and the lower image was taken using UV light.
Conservation at Nagaur Fort
Conservation interventions have included the removal of a polyvinyl acetate (PVAc) coating that was applied over some of the painted areas in the Hadi Rani and Sheesh Mahal. The coating was likely applied during the 1980s.
