Household appliances may include partially reflective (e.g., one-way mirror) glass as part of an oven door. The partially reflective glass may transmit light from an interior of the household appliance and may reflect light from outside the household appliance. Accordingly, one can see into the lighted interior but a camera inside the interior cannot see out through the door. In some examples, the household appliance includes a lamp and a camera disposed within the cavity of the appliance. The lamp and the camera are interlocked to protect user privacy by activating the one-way feature of the door glass as needed.

A cooking device according to one example embodiment includes a base having a top surface positioned to contact a cooking vessel configured to hold food during cooking. The base includes a heater having a ceramic substrate and an electrically resistive trace on an exterior surface of the ceramic substrate. The heater is positioned to supply heat generated by applying an electric current to the electrically resistive trace to the top surface of the base for heating the cooking vessel to heat food in the cooking vessel. In some embodiments, the electrically resistive trace includes an electrical resistor material thick film printed on the exterior surface of the ceramic substrate. In some embodiments, the electrically resistive trace is positioned on a top surface of the ceramic substrate that faces upward toward the top surface of the base.
