Supporting and Heating a Round-Bottom Flask
A round base cannot stand on the bench, so rest the flask in a cork ring or clamp it by the neck to a retort stand. Heat it on a water bath, sand bath or over wire gauze rather than in a bare flame, and add a few anti-bumping granules before boiling. Fill it no more than half full when distilling, so the liquid does not froth up into the condenser.
