 Prepare a fluted filter paper and stemless or short-stemmed funnel clamped above the filter flask. Pour a few $$\text{mL}$$ of solvent through the funnel, and allow the solvent to boil and get the funnel hot. When the mixture to be filtered is boiling, pour the mixture into the funnel in portions, returning it to the heat source in between additions. Rinse the filter paper with hot solvent if crystals are seen on the paper.
