We cool stir the oil using a magnetic stirrer for 14 days as in the original Paris study. We keep the oil in the dark throughout. We keep the glass flasks sealed to reduce exposure to oxygen. We are working on analysis of the oil throughout this 14 day period to determine the optimum stirring time. We are looking for the minimum time needed to dissolve the C60 and so reduce exposure of the oil to unnecessary stirring. We do not believe vigorous stirring is good for the oil as it will heat it up and introduce oxygen to the mixture.
