Abstract : An anomalous liquid phase forming in an atmosphere of reduced water vapor pressure was investigated. The liquid was grown in capillary tubes. Technical experimental refinements resulted in high nucleation rates not previously observed. An examination of vapor pressures disclosed the relationship of nucleation growth and equilibria of anomalous water. The possibility of nucleation and growth of anomalous water on flat surfaces was confirmed by observation. Anomalous water was nucleated and grown on glass, quartz, Teflon, polyethylene and metal. Growth rates on free flat surfaces were higher, and the total amount of fluid obtained was several orders of magnitude higher, than those obtained from capillary tubes. Refractive indexes and other properties were measured directly. The new method of growing anomalous water outside capillary tubes is an advantage that may lead to large-scale production. Neither investigation of nor conclusion on the nature of the substance was made. Its low freezing temperature, high boiling temperature, low vapor pressure and high viscosity, reported by previous investigators and observed by the author, are of primary importance and justify a search for large-scale preparation methods.
