Claim Text:
1. A ceramic footbath apparatus comprises a pair of boot-like footbath containers, wherein said footbath containers are made of ceramic material, and the footbath containers are sintered into double-layered containers having a hollow space between two layers, and wherein an inner layer of the two layers comprises lines with a pattern and attached thereon with a plurality of papillary extrusions corresponding to a reflex point zone of a user's feet, and wherein said pattern of the lines of the inner layer comprises honeycomb-shaped, hexagonal cylinder-shaped or porous network-like for increasing the surface area of the inner layer of the footbath containers in contact with water when water is added into the footbath containers and producing more counter electrodes due to the piezoelectric and thermoelectric properties of the ceramic material, thereby improving the effect of the plurality of papillary extrusions corresponding to the reflex point zone of the user's feet during footbath and massage, enhancing water turbulence to produce more weak static current at 0.06 mA that matches a bioelectric current of a human body, and leading to a release of more negative ions, minerals, trace elements and far infrared rays, and wherein the inner layer is non-glazed for preventing loss of far infrared rays from irradiation while an outer layer of the two layers is glazed for enhancing heat retention and thermal insulation inside the footbath containers.
