Abstract: A method of making a glass product includes: melting a batch of raw materials to form a glass melt in a melting tank; heating the batch and/or the glass melt using two or more electrodes, the electrodes including an electrode material and heating the batch and/or the glass melt includes operating the electrodes at a current frequency of at least 1,000 Hz and at most 5,000 Hz; withdrawing the glass melt from the melting tank; and forming the glass melt into the glass product.

Abstract: A baking oven including an oven muffle which includes at least one thermal heating element and which can be heated to various operational temperatures, i.e. a standard baking and roasting temperature and a high cleaning temperature (pyrolysis). The baking oven also includes a cooling fan arranged downstream from a ventilation shaft in order to guide heated air which is formed away from the inside of the baking oven to the outside thereof. According to the invention, at least one part of the ventilation shaft can be automatically adjusted according to various characteristics of the fan to form various cross-section flows by operation of a freely pivotable flap, in order to dispense with cumbersome conventional control measures.

Abstract: A baking oven defines a cooking space, in which a tubular, multiply bent radiant heating element is secured in a horizontally extending heating element plane. A temperature sensor for regulating the temperature of the cooking space is disposed substantially in the heating element plane and has a sensor tube that is disposed in close proximity to the radiant heating element for thermal coupling to the heating element. A temperature sensor with flexible leads is secured in the sensor tube for obtaining good coupling of the temperature sensor to the radiant heating element. The sensor tube has at least one curved portion, whereby the sensor tube curves around portions of the heating element. The heating element plane defines a measuring area lying in the heating element plane, and the temperature sensor is disposed approximately at a center of gravity of the measuring area and is substantially surrounded by the heating element.
