Sarah-Jane Clelland Wrote:@ P Prentice You raise an interesting point about grog. As it is after all fired ceramic, so what which would we be measuring the RHX reaction of, the grog or the main ceramic body? I am currently performing a series of experiments to see what is the best sample size to use. The samples in the PRSA paper were 4g, I am looking to see if we could use much smaller amounts of material (milli grams) in which case we could sample around the grog inclusions.
i would like to see the grog dated as well - might answer a few long standing questions relating to curating antique ceramics and the murky world of structured deposits - good luck
If they can get you asking the wrong questions, they don't have to worry about answers
