Commonly, a coffee maker comes with a glass carafe, but there are thermal carafes with double-walled containers made of stainless steel. The thermal carafe offers an excellent heating transfer feature and keeps the coffee hot for hours. This is just like a thermos or travel mug. Also, the thermal carafe keeps the freshness of the coffee intact and remains hot for a long time. However, they are typically heavy, and as compared to glass models, you can’t see the quantity of coffee in the pot. On the other hand, glass carafe is easy to break but affordable then thermal carafes.
