Cetinite is a complex antimony sulfide oxide. At the type locality, cetineite forms in pockets of antimony rich slag. It appears a list of 208 anthropocene minerals (Hazen et al., 2017), which are indicators of human alteration of natural mineralogy. Sabelli & Vezzalini (1987) named cetineite after the locality; an abstract of the original decsription appears in Jambor & Burke (1989). The AMI (Associazioni Micro-mineralogica Italiana) published an entire book on this popular and prolific collecting site.
Cetineite forms a orange lining in pockets to 3 mm. The matrix is a partly melted slag, showing residual stibnite and metallic antimony. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
