FOREWORD The history of glass-making in India goes back thousands of years when beads, bangles and other small glass items were made in kingdoms in North and South India and traded with other ancient civilizations such as Persia, Greece, and Rome. Indeed, the origin of glass bangles is perhaps as old as the Indus Valley Civilization; the famous bronze figurine of a dancing girl unearthed by archaeologists at Mohenjo-Daro (c. 2500 BCE) has her left arm and wrist completely encased in bangles. Interestingly, the very word bangle is derived from the Hindi word bangri, meaning glass bracelet! Over the ages, the bangle has come to be closely associated with the institution of marriage or suhag throughout India. Today, the nation buys an estimated 50 million bangles each day, and all these bangles are made by units in the small-scale glass industry cluster at Firozabad (or suhag nagri as it is popularly called), located about 40 km from Agra, the city of the Taj Mahal. Traditionally, Firozabad units use open pot furnaces to produce glass for processing into bangles. Besides the open pot furnace units, Firozabad also has hundreds of muffle furnaces or pakai bhattis to anneal the finished bangles. Till the mid-1990s these furnaces operated on coal and/or wood. undertook energy audit studies at that time, which revealed that the energy consumed by the furnaces was very high and that there was ample scope to reduce their existing levels of energy consumption. The Firozabad glass-making industry came into the limelight in December 1996, when the Supreme Court of India ordered 292 coal-based factories in the area known as the Taj Trapezium Zone, including the Firozabad pot furnace units, to switch from coal to cleaner alternative fuels such as natural gas, or else to relocate or shut down. Although the Court directed the government to supply natural gas as an alternative fuel to the affected industries, the pot
