Sinha enjoyed singing, painting, writing, and reading books. She had a large, rare collection of books and journals at home. At the age of 80, she continued to enjoy meeting people, conversing and reminiscing. When she joined the Central Glass and Ceramic Research Institute, Dr Sinha continued her work on clay minerals and ceramic colours. Amazingly, she also moulded the material that she studied in artistic ways and learned clay modelling. When not indulging her creative pursuits, Dr Sinha was translating science books into Bengali.
