This was stated by Minister for Culture Chandresh Kumari Katoch in Lok Sabha today.
According to her, the inscriptions on the bowl have been examined by ASI which ascribed them to 16th century AD in Nastalique (Persian).
"It is not possible to hold a view purely based on the information provided in several reports and travel accounts unless it is substantiated with factual archaeological evidence," she added.
The huge greenish-grey granite bowl weighs 400 kg and has a diameter of about 1.75 metres, height of almost four metres and thickness of 18 cm at its rim.
It is currently being displayed at the National Museum of Afghanistan.
