Short summary

This work deals with a challenging case of a commercial clay from Gomsiqe–Puka (Albania) contaminated by mineral fibres. Detection and quantification of asbestos in this material push the boundaries of current experimental methods. Using TEM, micro-Raman spectroscopy, and EPMA, we identified the presence of asbestos tremolite, along with a rare fibrous variety of diopside. The impact of milling on the detection and quantification of mineral fibres was also evaluated.
