Choosing and Fitting a Stopper
A stopper of the right size enters the neck by a third to a half of its length; one that slides almost all the way in is too small and can be pushed into the vessel. Twist the stopper gently when fitting or removing it rather than forcing it, and never close a flask that is still being heated, because pressure builds up inside.
Being solid, the stoppers can be bored with a cork borer when a delivery tube or thermometer has to pass through.
