A Copper Half Hammered Glass could refer to a drinking glass made from copper, with the bottom half of the glass featuring a hammered texture, while the top half is smooth or untextured. The hammered texture can give the glass a unique look and feel, as well as providing a good grip. Copper is a good conductor of heat and can keep drinks cool, making it a popular material for drinkware. The glass could also be coated with a food-safe material to prevent the copper from reacting with acidic drinks.
