The Owens College Junior Course of Practical Chemistry (Classic Reprint)

Glass stirring-rods. Divide a piece of glass rod into several pieces about tvo decimetres in length. This is done by riling the glass rod at each place where it is to be cut off, with a three-cornered file, and then snapping it across. Knock off any projecting pieces of glass which may be left at the newly-cut edges, and then hold each end of the rod in the flame of a Bunsen lamp until the sharp edges are fused and rounded. The glass rods thus made serve for stirring liquids. c. 2. A -wash bottle. Soften a cork by gently rolling it under the foot, and fit it air-tight into the neck of a flask about one litre capacity. Then, by means of a round file, bore two holes in the cork about three millimetres in diameter, A doubly-bored india-rubber stopper may be used instead of a cork.
