Table 2: Selected representative ID Data on the identified minerals accompanying the sapphires in the new E(IM1)-heat treatment runs. Samples cut in half and polished.
Fig. 7 In February 2002, Chrysoberyl samples were investigated by SEM at ZMB (University of Basel (Switzerland)). From left to right: Dr. A. Peretti with M.Duggelin and D. Mathys.
Fig. 8 A set of non-sapphire materials sorted after heat treatment experiments. In December 2001, heat treatment was carried out with the new method in Chantaburi (Thailand) on a lot of briolette sapphires and then inspected by GRS at the source. First row: Melted non-sapphire materials transformed to whitish glass- aggregates. Second row: Zircon minerals (radioactive). Third row: Chrysoberyl minerals. (Note: Craters on the surface of the zircon and Chrysoberyl crystals due to contact with other minerals in the heat treatment process and partial melting of the surface, See arrows). Overgrowing layers of thin films with interference colors were found on zircon and Chrysoberyl samples, indicating some chemical reactions on their surfaces. Samples collection GRS.
