This thesis is concerned with a better understanding of issues which currently limit the precision, accuracy and robustness of rehydroxylation (RHX) dating.

After firing minute amounts of water slowly combine chemically with the ceramic leading to a very gradual, very small, gain in weight.

This weight increase happens at a predictable, but slowly declining, rate over hundreds or perhaps thousands of years, and is easily measured.

The very first point to remember is that bricks are regularly re-cycled; consequently bricks may well be older than the buildings that contain them.

Secondly, any attempt to date British bricks stylistically must allow for regional variations; the size of pre-18 century bricks, and their arrangement, did not conform to any nationwide standards.

Before that the observed mass gain is due to several processes occurring simultaneously (Stage I). The proportionality constant a T is the slope of the linear portion of the mass vs.

t¼ plot shown in Figure 3 when the data are acquired at temperature T.

The use of microgravimetric instruments using the Aquadyne DVS Gravimetric Water Sorption Analyzer for RHX dating was pioneered by research at the University of Manchester. Aquadyne DVS Gravimetric Water Sorption Analyzer The RHX dating methodology is quite straightforward, however producing data of enough quality to offer an age estimate for a fired ceramic piece is more difficult as a super-slow rate mass gain due to RHX needs to be measured which is an increase of 6 mg over 3 days.This is the combined mass gain of all the three types of water identified T0 T1 T2 (~27,000 data points).The contribution these components make to the overall mass can be separated out as shown by graphs (b) and (c) (b) mass gain due to T0 T1 only and this eventually stops when the sample has equilibrated with the ambient conditions.For more information on this source, please visit Quantachrome Instruments.Tim Nunney In this interview, Tim Nunney, Marketing Manager at Thermo Fisher, speaks about the capabilities of the Thermo Scientific ™ Nexsa™ Surface Analysis System, and how it can be used to gain insight into 2D materials.
