The carafe is made of non-stain, heat-resistant borosilicate glass that won’t alter or impair the coffee’s natural flavor. The frame and lid is made from durable stainless steel that’s undergone several chrome-plating processes to result in a durable, shiny surface capable of withstanding many years of us. The handle is made from Polypropylene with a matte finish that gives a comfortable grip while serving and adds to the classic quality of the design. Stainless steel plunger prevents ground beans escaping when the coffee is poured.
