A copper hammered glass is a type of drinkware made from copper that has been hammered to create a textured surface. The hammered effect on the glass not only enhances its aesthetic appeal but also provides a better grip while holding. These glasses are generally used to serve cocktails, juices, and other cold beverages. The copper material is known to keep drinks colder for longer periods due to its excellent thermal conductivity properties. Additionally, copper has antimicrobial properties that make it a popular choice for drinkware as it inhibits the growth of bacteria and keeps the glass hygienic.
