Ether
Usually packed in small metal cans or bottles with stoppers. Metal cans usually have metal stoppers secured by means of solder. The stoppers are liable to be jarred loose during transit. In which case lables may be found to be stained and part of the original fluid content lost due to seepage and evaporation. When packed in bottles with press caps, vapour may escape, although the cap may have the appearance of being quite secure. Sometimes bottles have glass stoppers and paper caps tied with string and dipped in wax. When stowed out of the upright position the stoppers may become loose, allowing the contents to melt the wax, which may give rise to loss due to evaporation.
