The city of Firozabad is famous primarily for its glass industry , especially for the production of glass bangles. It is known as the "City of Glass" or "City of Bangles" because of its extensive glassmaking tradition, which dates back over 200 years. The city has around 150 to 400 glass factories that produce a variety of glass items such as bangles, glassware, chandeliers, and bottles. The colorful bangles made here hold cultural significance in India, symbolizing prosperity and good fortune for married women and new brides. Firozabad's glass industry grew historically from the melting of rejected glass items brought by invaders, which were remade into bangles and glass products. Despite its fame, the industry is also known for harsh working conditions, including the exploitation of child labor. The city is located near Agra in Uttar Pradesh, India, and has a population deeply involved in this glassmaking craft. In addition to glassmaking, agriculture and handicrafts contribute to the city's economy, but the glass industry remains the defining feature of Firozabad's identity and economy.
