Hello Tamara, Thanks for your reply. In the lab we have worked with the carbohydrate ideas, so travelling down the same path. With the grindstones we are looking for some tests that we can also carry out in the field as sometimes we have grinding hollows or stones in situ which can not be moved. This is why we thought simple visual staining and utilising a hand held digital microscope could be the answer. However the staining is not as straight forward as we'd hoped. I am thinking that if the Phloroglucinol is light sensitive then perhaps counterstaining with Toluidine Blue can highlight other areas. Problem is the residues are water lifted and drowning the slide with tap water (well drops of) means that the residue at times almost vanishes. Any more thoughts are most welcome.
