Agra News : During the G-20 event in Agra, Uttar Pradesh, tell-tale glasses were planted by the Archaeological Survey of India in the widened cracks in Diwan-i-Aam of Agra Fort. After its study, it was decided that it would be allowed to continue for three months till May. After this the cracks will be studied again. Till then barricading will continue in Diwan-e-Aam.
On the night of February 11, projection mapping and cultural presentation was done by the Ministry of Women and Child Development for the G-20 delegation at Diwan-e-Aam. It was said that due to the loud noise in it, cracks had appeared in the monument. Here on February 10, there was a loud sound echoing throughout the night rehearsal, only after which the cracks widened. After this, the Archaeological Survey of India (ASI) has put barricading in Diwan-e-Aam.
Tell-tale glass has previously been installed in the Taj Mahal, Jama Masjid and Jahangiri Mahal in Agra Fort. Tell-tale glass has been installed in the upper floor of the Jahangiri Mahal of the fort, the basement and the upper floor of the Taj Mahal. It was installed outside on the south-eastern bastion of Jama Masjid, to study the effect on Jama Masjid due to vibrations of trains passing through Agra Fort station. It is still there today. Here the speed limit of the train has been fixed at 20 km.
Tell-tale glass is thin glass like a glass strip used to take a blood sample, which is applied with spices to the cracks in the monument. When the width of the crack increases, it breaks due to pressure. From this it is known that the width of the crack is increasing. Superintending archaeologist Dr. Rajkumar Patel told that the study will be done by applying glass for three months. Recently, even after the program of Shivaji Jayanti, the ASI had checked the tell-tale glass. There was no growth in its cracks.
