Ceramic coffee drippers are manufactured by Hario, Melitta, Bee Hive, Bonmac (Hario?), Cilio (Frieling) and others. The advantage is that they are essentially glass (the glaze is glass), which is non-intert, meaning there is no possibility that taste will be affected by the material as is possible with plastic or resin coffee drippers.
They can break and are more expensive than plastic.
If you’re not prone to breaking things ceramic is a good way to go, if purity is key and you don’t want the added cost of glass.
