Produce high-function water useful for consumption as healthy drinking
water or in the production of health supplements, cosmetic products, food
preservatives, freshness-keeping agents for food, insect repellents or
deodorizers, wherein such water contains micro-dispersed ultra-fine gold
particles and a small amount of dissolved gold and is produced by
constructing in the upper section of a high-pressure water tank a
combustion chamber equipped with an injector nozzle for oxygen-hydrogen
mixture gas, an ignition device and a gold-rod or gold-wire feeder,
igniting the injector nozzle for oxygen-hydrogen mixture gas using the
ignition device in the combustion chamber to melt and evaporate the gold
rod or wire supplied from the feeder or water in which gold foil was
dispersed beforehand and to allow the produced gold vapor to contact
high-pressure water, and thereby causing the produced ultra-fine gold
particles to float and disperse in water.
