Separation of lead glass and glass ceramics

REDWAVE XRF-G Sorting machines are used in glass processing for the separation of lead glass and ceramic (heat resistant glasses). The elemental composition of the fragments is analysed by X-ray fluorescence spectroscopy. Particular elements, such as zinc, zirconium, strontium or lead, are searched for, to allow a precise evaluation of the shards. Contaminants are identified and separated.
