GloTell, is an anhydrous ammonia additive, formulated to be introduced into ammonia to serve not only as a theft deterrent for methamphetamine production, but also a leak detector and marking agent. GloTell, when injected into the anhydrous ammonia, stains exposed surfaces pink. This pink color is detectable by ultraviolet light, affording law enforcement personnel a method to detect persons that have encountered the product while producing the illegal drug, while also reducing the quality of methamphetamines.
