Asbestos-containing pottery shards collected in the northeast of Corsica (Cap Corse) and
dating from the 19th century, or earlier, have been analyzed by SEM-EDS, XRPD, FTIR and Raman microspectroscopy. Blue (crocidolite) and white (chrysotile) asbestos fiber bundles are observed in cross-sections. Most of the asbestos is partly or totally dehydroxylated, and some transformation to forsterite is observed to occur, indicative of a firing above 800 C. Examination of freshly fractured pieces shows a nonbrittle fracture with fiber pull-out, consistent with ...
... forced ceramic matrix composite. Residues indicate
the use of this pottery as a crucible for gold extraction using cyanide.

1. Introduction
The fracture of a ceramic gives rise to a brittle edge, and fracture initiation depends upon the

... preserved, as evidenced by
the pull-out over lengths on the order of several millimeters. This testifies to an empirical mastery of
the manufacture of CMC.
Observation of a black core or side for all samples (Figure 1), as well as the carbon doublet
(1370–1600 cm-!) in many places, is consistent with ...
