It joins two Greek words — *klino*, to incline, and *klasis*, to break — because the mineral splits cleanly along a plane set at a slant rather than square to its faces[1]. Cleavage is simply the direction along which a crystal breaks most easily, and in clinoclase that direction runs oblique.\n\nThe German mineralogist August Breithaupt coined that name in 1830, choosing it precisely for the oblique cleavage he saw[1]. The mineral itself was first found in Cornwall, in south-west England[2]. Its type locality — the place whose specimens define the species — is the Wheal Gorland mine at St Day[2].\n\nClinoclase belongs to the oxidised zone of copper deposits, the shallow region where weathering has broken down the original ore. There it grows as a hydrous copper arsenate, often in fine needle-like crystals[2]. It is a rare mineral, and for most of its history it has been a subject for the collector's cabinet and the mineralogist's notebook rather than a working stone.","claude-opus-4-8","1.7.0",{"markdown":495,"model_version":492,"prompt_version":493,"reviewed_at":11},"Clinoclase has no industrial use. It is far too rare for that, and it carries nothing a factory would want. Instead it is sought by mineral collectors and studied by mineralogists, prized for its sharp needle-like crystals — a striking representative of the rare copper arsenates of weathered ore[1].\n\nOne word of caution attaches to any specimen. Clinoclase is a copper arsenate, meaning arsenic is built into its chemistry[1]. Handle samples with clean hands, keep them away from food, and wash after touching them. The mineral is stable on a shelf, but its dust should not be inhaled or ingested."]
