A slow cooker consists of a lidded round or oval cooking pot made of glazed ceramic or porcelain, surrounded by a housing, usually metal, containing a thermostatically controlled electric heating element. The lid is often transparent glass and is seated in a groove in the pot edge; condensed vapor collects in that groove and provides a low-pressure seal to the atmosphere.

"A horizontal tubular, which is found to be extremely powerful as well as economical. It is a rectangular box 6 feet long, made of 2-inch iron pipes, fixed into hollow water spaces which form the ends; these pipes act as fire bars, and form the sides of the furnace. above the fire there are three series of horizontal pipes, each covered by a layer of tiles so placed as to convert the two intervening spaces into flues, along which the flames and smoke travel for 18 feet, the smoke escaping at the far end by an opening in the upper layer of tiles." — Encyclopedia Britannica, 1893

"The simple outline of the atmospheric engine. Its mode of operation is as follows. Steam is admitted from the boiler into the cylinder, through the tube l, by means of a regulating cock, e, which is worked by a handle outside the boiler; the pressure of the atmosphere above the piston being thus balanced by the force of the steam beneath it, the extremity of the lever beam to whch the piston is attached is elevated by proportionate weights, w, attached to the pump-rod, and the piston is drawn to the top of the cylinder, the other extremity of the beam being depressed." —Comstock, 1850
