Q. When was the Indian Lac Research Centre, Namkum, Ranchi, founded?
Answer: 1924
Notes: The Indian Lac Research Centre, now Indian Institute of Natural Resins and Gums, was founded on 20 September 1924 in Namkum, Ranchi, Jharkhand. It originated following the 1920 Lindsay-Harlow Committee recommendations and the Indian Lac Association formation. The centre became operational under the ICAR mandate for lac research, processing, and development. Its name was changed to IINRG in 2007. Some sources cite 1925 approximately, but primary records confirm 1924 as the founding year.
