Ceramic disc faucets are an alternative to rubber washers which degrade over time. They are much tougher and able to deal with extreme temperatures. They are operated by applying a quarter turn (excessive pressure can damage the ceramic discs). Older faucets need two full turns. Ceramic discs can be impacted by hard water making them less durable.
