<p>Method for determining the purity of prepared used glass, in which the sample quantity is removed from the stream of prepared used glass and the foreign bodies still contained therein are sorted, and non- ferrous metals and opaque foreign materials, such as ceramic and porcelain particles and stones, are sorted out, weighed and are set in relation to the weight of the total sample. In order to be able to analyse a sample simply, it is provided that the sample is poured out in a single layer and is allowed to trickle over a free-fall path and foreign bodies consisting of non-ferrous metals are blown out and subsequently opaque foreign bodies are blown out and are collected in containers separately from the non-ferrous metals. <IMAGE></p> |
