CSIR-Central Glass & Ceramic Research Institute


First Decade (1950s)

  • Research on coloured glass, sintered glass and foam glass. Foam glass with good thermal insulation and buoyancy promised use in roofing materials
  • Development of green glasses. Work pursued on red signal glasses
  • Trials on electric furnaces. One of the furnaces was designed to specifically test / trials on foam glass
  • Testing of refractory bricks by the navy for various parameters
  • Research to develop hot face refractories from indigenous raw materials like high alumina clay and kyanite
  • Eight new on-glaze colours of different shades of yellow, blue, green, red, red-brown were formulated and tested that compared favourably with imported Blythe’s colours A process developed for making insulation bricks from waste mica
  • A unit pilot plant for the production of optical glass was recommended to be set up by the Glass and Refractory Research Committee of CSIR
  • Development of porcelain spark plugs with 95% Al2O3 body
  • Development of sun-glare glass
  • A bulletin called CGCRI Bulletin was started for disseminating R&D in the frontier areas

Second Decade (1960s)

  • Consolidated the infrastructure for the production of optical glass. Manufactuing operation for the same was set up and the institute plant went into operation in 1961.
  • 25 varieties of optical glasses were developed on basis on customer demand. Quality compared to international standards interferometers, cameras, binoculars, range filters
  • Development of tank periscope prisms for armoured vehicles
  • Glass slabs from special glasses with high lead content to cut off radiations
  • Optical glasses were supplied in random slabs for being used in microscopes, telescopes, interferometers, cameras, binoculars, range fllters
  • Special infrared transmitting glass. Required n the defence sector for use in vehicle head lamps
  • Synthetic quartz single crystals developed using hydrothermal techniques. The work was extended to pilot plant scale
  • Glasses for glass-to-metal seal. These were required to make electronic valves
  • High temperature porcelain enamels for aero-engine parts useful in jet exhaust systems
  • Work for making Heat insulating bricks for waste mica continued. Three Indian firms took up the process and began manufacturing. Began to be used in steel plants, industrial furnaces, oil refineries, textiles, paper mills as substitute for imported vermiculite bricks. By 1967, bricks worth Rs 1.14 crore was being sold by the firm.

  • Large initiatives of import substitution included process for manufacture of glass bonded mica, low impedence glass electrodes, inorganic bonded commutator type micanits, glass ceramic materials for industrial jewels
  • Process of manufacture of abrasion resistant glass ceramic tiles for lining the chutes of coke oven
  • Initiation of work on process of fixing high level atomic waste
  • Supply of 30 variants of optical glass to defence
  • Development of special infrared transmitting glass and arsenic tri sulphide filters for defence
  • Nd-doped laser glass rods for latest types of range finders of 5-10 km range
  • Further development of quartz single crystal
  • Establishment of Naroda Centre to facilitate R&D for product development, testing and characterization, training and demonstration activities in traditional ceramics

Fourth Decade (1980s)
