Abstract
Induction-heated vessels, and processes for manufacturing induction-heated vessels and vessel components, are provided. The vessels can include a ceramic outer layer and a conductive heating element, which can be provided as a conductive glaze or coating, a conductive inner layer, or a label comprising a conductive element and an RFID tag, to allow the thermal transfer or conduction of heat from the heated surface directly to the contents of the vessel, while the ceramic outer layer of the vessel insulates the contents of the vessel. Also, systems and methods for heating and controlling induction-heated vessels and for tracking loyalty, use, and/or sales using RFID-enabled induction-heated vessels are provided.
Claims4
A heated ceramic vessel comprising:
- a ceramic container body for insulating the contents of the vessel, wherein the ceramic container body comprises a base and a sidewall, and defines a chamber in which the contents of the vessel are stored, and wherein the base and sidewall define an outer layer of the vessel;
- a conductive heating element for thermal transfer or conduction of heat to the contents of the vessel;
- and
- a radio-frequency identification (RFID) tag for identification and tracking of the vessel;
- wherein the conductive heating element comprises at least one of:
- a conductive glaze or coating on an inner surface of the ceramic container body;
- and
- a conductive inner layer on a base of the ceramic container body;
- or
- a label comprising a conductive element and the RFID tag;
- wherein the conductive glaze or coating comprises one of:
- a ceramic glaze with a semiconductor system, wherein the semiconductor system comprises copper and at least one of tin and tin oxide doped with antimony;
- a silica-carbon black coating;
- or
- a silica-ferrite coating.
