Abstract
A method for determining the purity of treated used glass, in which the sample quantity is taken from the treated used glass stream and the foreign bodies still contained therein, separated according to non-ferrous metals and opaque foreign materials such as ceramic and porcelain particles and stones, are sorted out, weighed and put in relation to the weight of the whole sample. In order to be able to analyze a sample in a simple manner, it is provided that the sample is piled in one layer and allowed to trickle over a free-falling path and that foreign bodies made from non-ferrous metals are blown out and thereafter opaque foreign bodies are blown out and collected in containers separate from the non-ferrous metals.
