Solid stoppers do the quiet jobs of a practical class. Students stopper a test tube before shaking it to dissolve a solid or compare solubility, close a tube of collected gas until it is ready for the splint test, and seal small reagent or sample bottles so that dust stays out and evaporation is reduced. They also blank off a spare neck while apparatus is being assembled, which is why technicians keep a box of each size in the preparation room.
Never close a tube or flask with a solid stopper while it is being heated or while a reaction is still giving off gas: pressure builds up and can push the stopper out or crack the glass. Press the stopper in with a slight twist rather than a hard push, and ease it out the same way. If a set-up later needs a tube through the stopper, a hole can be bored with a wetted cork borer.

Can a solid stopper close a tube that is being heated?
