PROVENANCE:
From the private collection of Kenneth Machin (1936-2020), Buckinghamshire, UK; his collection of antiquities and natural history was formed since 1948; thence by descent.
FOOTNOTES:
Carborundum rarely occurs in nature, but is commercially formed by heating carbon and silicon at very high temperatures, producing extremely strong bands of crystals.
