This program was developed to serve the multiphase modeling requirements of TOF –ND data analysis. Initial
modeling of the experimental data during the refinement process adopted a quartz, feldspar, plagioclase,
hematite and diopside mineral combination (see Fig 3), according to earlier ND analysis [6]. Preliminary
analyses revealed that in all diagrams quartz and feldspars phase fractions are dominant.

Diopside and iron oxide phases were also identifiable. The diopside content is found to decrease with
increasing quartz - feldspar compositions. Further more the plagioclase content is increased almost linearly with
the temperature. The hematite content in the sample remains almost constant above 700 ºC and is in excess of
7% . Based upon the data collected in the second step, the firing temperatures of the pottery samples were
determined to be within 850 to 950ºC.
