Haven’t heard of cylindrite, but have heard of a clay that rolls its sheets up into cylinders, is this similar?

Checks web.

No it’s not chemically similar, but like the clay it does roll its sheets up into cylinders. “Cylindrite is a sulfosalt mineral containing tin, lead, antimony and iron with formula: Pb3Sn4FeSb2S14. It forms triclinic pinacoidal crystals which often occur as tubes or cylinders which are in fact rolled sheets.”
