Then the constitution of the Council of Scientific and Industrial Research (CSIR) as an autonomous body was prepared under Mudaliar and Bhatnagar. Thus, CSIR came into operation on 26 September 1942. The BSIR and IRUC were incorporated into the advisory bodies to the governing body of the CSIR. In 1943 the governing body of CSIR approved the proposal of Bhatnagar to establish five national laboratories — the National Chemical Laboratory, the National Physical Laboratory, the Fuel Research Station, the Glass & Ceramics Research Institute and the National Metallurgical Laboratory. In 1944 in addition to its annual budget of ₹10 lakh, CSIR received a grant of ₹1 crore for the establishment of these laboratories. The Tata Industrial House donated ₹20 lakh for the chemical, metallurgical and fuel research laboratories. The foundation for the Central Glass and Ceramic Research Institute at Kolkata was the first to be laid, in December 1945; National Metallurgical Laboratory at Jamshedpur in November 1946; and that for the National Chemical Laboratory at Pune was the last, on 6 April 1947, four months before India became independent. All the five establishments were completed by 1950.
