Eerst worden de potten grondig schoongemaakt, bijvoorbeeld met <a href="/wiki/Natriumcarbonaat" title="Natriumcarbonaat">soda</a>. Daarna worden ze gevuld met de in te maken levensmiddelen (<a href="/wiki/Groente" title="Groente">groente</a>, vruchten, vlees enz.). De potten worden afgesloten met een glazen deksel. Tussen pot en deksel komt een rubberen ring, de weckring. Om het deksel op zijn plaats te houden wordt het vastgezet met een metalen beugel. </p><p>De potten worden daarna in een waterbad, gewoonlijk in een weckketel, verwarmd en <a href="/wiki/Asepsis" title="Asepsis">gesteriliseerd</a>. De uitzettende lucht in de pot kan ontsnappen, waarbij de beugel voorkomt dat het deksel en de ring verschuiven. Bij het afkoelen zorgt de rubber ring voor een <a href="/wiki/Luchtdichte_sluiting" class="mw-redirect" title="Luchtdichte sluiting">luchtdichte sluiting</a> en wordt het deksel door de atmosferische druk op de pot gedrukt. De beugel is dan niet meer nodig en de inhoud kan jarenlang worden bewaard. </p><p>De fles of pot kan worden opengemaakt door aan het lipje van de weckring te trekken. Daardoor wordt de onderdruk verbroken die het deksel stevig op de pot houdt.
