Saw this at NID, not many know that metal and utensils were my family business. We still have an aluminium utensil factory in Palamau, Jharkhand.
The "Lota" is an integral vessel in homes here. These come in aluminium, brass, steel and copper. Different faiths use them for different purposes. Some use it for ritual purification. Invocation of mantras in a pooja starts with "jal" and flowers in it. It is mainly used as a vessel for water and also helps in the kitchen. Sadly these days, plastic ones are also vying for space amongst shelves in local shops.
