Our two dating methods can only be made consistent using the recommended calibration curve (1986) instead of the revised one (1993). ... We have performed a high-precision14C wiggle-matching study on two oak beams from the "Castle of Amsterdam". These beams are also dated by dendrochronology. ...

.- high ring samples were weighed on gram scales reading directly to 0.1 gram. ... The upper ring was purposely left unfilled so that no pressure would be applied on the surface of the sand that might cause compaction in the test sample. ...
The rings were lubricated with silicon greaseto reduce side friction, and filter papers were placed on top and bottom of the sample to prevent the clay from being forced intothe porous stone. ... Torblaa.11 The experiments on the first three clays shown in the table were conducted while the writer was at Imperial College, using samples of 3 in. diameter and 3/4 in. thick in a brass ring. ...
