Doughnut charts of engineered stone (ES1-5) and natural stone (NS) dusts illustrating mineral phases and resin content measured by Raman spectroscopy. Each chart displays the relative content of mineral phase that is coated with resin (decorated pattern). Abbreviations were based on Whitney and Evans (2010)34: Qtz: quartz; Crs: cristobalite; Rt: rutile; GC: glassy carbon; Ab: albite; Ms: muscovite; Gbs: gibbsite; VP: vitreous phase.
