Most replacement carafes are made from glass (commonly borosilicate or soda‑lime glass). Some models are made from acrylic or other plastics.
Carafes are sold as single units and in multi‑piece sets. Common configurations shown include single carafes, 2‑piece sets (e.g., carafe plus tumbler), and 3‑ or 4‑piece sets.
Listings mention soda‑lime glass (described as thermally tough or durable), borosilicate glass, and references to durable, scratch‑resistant glass in some descriptions.
