Core drills

From: Helena Jaeschke <mrshjaeschke>

George Hagerty asked for advice on obtaining very small core drills
for ceramics. A more serious problem than the disintegration of the
core into particles may well be the heating due to friction of the
ceramic material, corrupting the eventual TL reading. I would
suggest checking with the lab undertaking the TL dating before
drilling real artefacts and even comparing results by drilling
fragments or break areas of pots with very similar composition.

Best wishes
