Glass industry in Firozabad, Uttar Pradesh, has an ancient history which dates back to the time when invaders used to bring glass articles to India. During that era, the rejected glass articles were collected by the local folks and were melted in the local furnaces known as Bhainsa Bhatti. This marked the initiation of glass industry in Firozabad. These ancient traditional furnaces are still used in Sasani near Aligarh and at Purdal Nagar and wood is used as a fuel. Initially only one bangle at a time was made in these furnaces and the bangles were devoid of any joint. The bangles were termed as 'Kadechhal Ki Chudi'. Firozabad has been the site of a major glass industry since that time and extensively manufactured white and coloured glass pieces which found their utility in assembling of chandeliers. Chandeliers had a great demand in the royal courts and were used as exquisite embellishments. Later, containers for scents and other cosmetics products were also made. Gradually the industry began producing marriage ornaments in a large scale. The place manufacturing such products became popular as Suhag Nagar as it fulfilled all the ornamental needs of married women, also known as 'suhagins'.

Firozabad has acquired a special place in the production of colourful and artistic glassware since 1989. Presently, the place has registered four hundred glass industries which are specialized in manufacturing varied glass products. Nowadays natural gas is used as fuel.
