I have a Narin~o, PreColombian?, human figure vase. It is 14 inches high. The face is triangular with geometric designs. His hands are raised toward his neck. In one hand he holds a small cup. In two black bands coming from between his hands there are circles with random dots in them. They resemble slices of ayahuasca. The handles of the vase are two loops on each side and resemble vines. On the back side there are several more circles with random dots and many scrolls or S figures. In the bottom of the vase there is possible residue from whatever may have been in the vase. I would like to have the vase tested for ayahuasca alkaloids, specifically harmine. Prof. Dennis J. McKenna recommended that I contact this site to try to find a lab that can do this test. I would also like to have the vase tested for age. Can anyone recommend such labs. If the vase tests positive, it may be evidence for early ayahuasca use. Narin~o, Columbia, is in the region where ayahuasca was used. Thank you for any help you can give me.
