"Steel glass" is a term commonly used in India to refer to a specific type of drinking vessel. It is essentially a small, cylindrical container made primarily of stainless steel, often with a glass or transparent lid. This unique fusion of steel and glass in a single item serves various practical and cultural purposes in Indian households.

In Indian culture, steel glasses are preferred for several reasons. Firstly, stainless steel is a durable and hygienic material that does not react with the liquids it holds, making it a popular choice for serving beverages. Additionally, steel glasses are eco-friendly, as they are reusable and reduce the need for disposable plastic or paper cups. This sustainability aspect aligns with the growing global awareness of environmental concerns.

These steel glasses come in various sizes, with smaller ones typically used for serving water, juice, or lassi (a traditional Indian yogurt-based drink), while larger ones may be used for tea or coffee. They are especially common in South Indian households, where "tumbler" is another term for these steel glasses.

Moreover, steel glasses are a staple in traditional Indian dining, often accompanying thalis (round metal trays with several compartments) in restaurants or homes. They are integral to the cultural experience of enjoying Indian cuisine, encouraging communal eating and sharing of food.

Beyond their utilitarian role, steel glasses hold cultural significance. They are a symbol of simplicity and humility, reflecting the idea that the most basic and essential things in life are often the most valuable. This cultural ethos is deeply ingrained in Indian society, emphasizing values of frugality and practicality.

In conclusion, the term "steel glass" in India refers to a stainless steel drinking vessel with a glass or transparent lid. These versatile and eco-friendly containers are not only functional but also carry cultural significance, embodying the values of simplicity and sustainability while playing an essential role in Indian cuisine and dining traditions.
