Glass is a unique material for the expression of art and craft. Amongst all material, it offers the highest degree of flexibility for shaping into a wide variety of products varying in design, forms, color and appearance. During ancient times, settlers brought many glass articles to India. These glass articles, when rejected, were collected and melted in locally made furnaces called "Bhainsa Bhatti." In this furnace, wood was used as a fuel. These old traditional furnaces are still in use in Sasani near Aligarh and at Purdal Nagar and were originally used only for making smaller bottles and bangles. By current production standards, only one bangle at a time can be made using these furnaces. These bangles had no joints and were locally known as "Kadechhal Ki Chudi". Over time, production slowly became more widespread among the locals. This was the start of the glass industry in Firozabad. Since then Firozabad has been the home of India's glass industry. White and coloured glass pieces being manufactured for the purpose of assembling jhad and fanus (chandeliers) which were in demand by royal courts and nobles for decorating their assembling and drawing rooms. Later on phials for Itra, scents, and other cosmetic products were made. Gradually, Indian marriage items like bangles, kangans, kada, etc. too began to be produced in bulk for the general public. 

production of these units is exported. Nowadays, blowing/modeling is done by the Pot furnace and Regenerative tank furnace. Firozabad Glass Work received GI tag in the year 2014.
