Vector generated image of Halogen Bulb:The halogen bulb uses a design very similar to that of conventional light bulbs, consisting of a tungsten filament enclosed in another material. The halogen bulb uses quartz instead of glass, however, allowing the bulb to be much smaller because quartz can...

Vector generated image of chimney:IA chimney is a structure for venting hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the...

3D render image of Dreschel Bottle:In 1875, Drechsel invented the device for which he is remembered - a gas jar topped with a single ground glass joint into which fits a stopper that combines a long gas inlet tube, reaching to the bottom of the device, and an outlet. Even highly corrosive gases...
