Notes<br />

Sample 1: 105 Wall Nogging Brick appears to have been poorly fired, if it was fired at<br />

all. However, after more than 200 years, the nogging in this wall is in fine condition,<br />

which means that there are no leaks or rising damp issues, in this area at least.<br />

The absorption behavior of both samples is consistent with that of the chimney and<br />

nogging brick used in the RILEM test, with the chimney bricks being better fired and<br />

thus less absorptive.
