Did you know that, other than porcelain, ceramic, metal, plastic, styrofoam, and paper, there is an entire universe of glass coffee cups?
Some people prefer them because glass allows you to see the contents of what you are drinking. Coffee drinks such as cappuccino or mocha can also be seen from the side for added entertainment value.
Glass doesn’t chip as often as ceramics, making it much more durable for commercial activities. They also offer very competitive prices as well. And glass cups keep most of the same properties of porcelain cups, namely having a smooth and non-porous surface, being easy to clean, not adding any chemicals to your beverages such as a metal or a plastic cup, and excellent thermal insulation to preserve the temperature in the coffee while you also do not bur your fingers holding the cup.
