A testwork programme has demonstrated that feldspar and quartz from spodumene concentrate at the Mina do Barroso project, in Portugal, are suitable for use in a range of glass and ceramic applications, London-listed Savannah Resources reported on Tuesday. The company said that the testwork had validated the feldspar from the project for both ceramic bodies and glazes, as well as float and container glass, in addition to validating Mina do Barroso quartz for lead crystal and container glass.
