Advanced technology is transforming archaeological conservation in Lumbini

In Lumbini, Nepal, a pioneering initiative is equipping archaeologists with advanced technology and scientific methods for heritage conservation. Trainees like Chandra Prakash Pathak are meticulously learning to handle ancient artifacts under the guidance of experts, understanding that even minor errors can irrevocably damage historical objects.

To conserve an archaeological object effectively, the absolute first step is identifying its underlying decay.

Senior archaeology officer Shanti Sharma emphasizes the critical first step: identifying decay. Using specialized laboratory lenses, she examines ancient fragments under a microscope to detect microscopic structural damage before planning interventions. Sharma, who has participated in major excavations in the Lumbini area, notes the shift from relying solely on theoretical knowledge to applying practical, technical expertise gained from global experts.

“

Right now, I am placing these ancient fragments directly under a microscope to pinpoint microscopic structural damage before determining an intervention.

This intensive training program, involving ten archaeologists, officers, and advanced students, marks the first systematic introduction of high-tech lab equipment and scientific diagnostic methods for heritage conservation in Nepal. Led by renowned art conservation specialist Anupam Sah, participants are documenting every phase of treatment and creating digital logs. While manual and mechanical techniques are preferred for preserving historical integrity, chemical treatments are reserved for severe cases, with patch tests conducted first on inconspicuous areas.

Before this, our training was mostly confined to textbooks. Being able to apply these advanced techniques directly in a high-tech laboratory to save museum pieces is incredibly fulfilling.

The workshop, held from April 18 to May 18, was facilitated by the establishment of a state-of-the-art conservation laboratory within the Lumbini Museum, which is operated by the Buddhist Foundation with financial assistance from the Government of India. Participants express fulfillment in applying these advanced techniques to save museum pieces, a significant upgrade from their previous reliance on textbooks.

We have gained an immense amount of practical skill. Chemical treatments are reserved for severe cases. Even then, we perform patch tests on invisible or reverse sides of an artifact first, observing the chemical reaction before proceeding with full restoration.
