Dos processos, que generalment actuen conjuntament, contribueixen a la formaci\u00f3 de les calc\u00e0ries En el neol\u00edtic, abans de descobrir la terrissa la qual elabora peces de fang cuites, els humans ja utilitzaven el fang (argila mullada i pastada) per a fer-se utensilis per a les seves necessitats, tals com posar-hi menjar sec, cereals i d’altres productes, per\u00f2 no aix\u00ed els l\u00edquids, ja que no eren estancs. M\u00e9s tard es va descobrir la terrissa cuita, m\u00e9s forta i estanca, la qual ja permetia posar-hi l\u00edquids.

\nEls primers usos de l’argila foren l’elaboraci\u00f3 de tot tipus d’atuells estancs per a contenir productes necessaris per als establiments humans: plats, gots, olles, cassoles, etc. Aquests atuells foren especialment \u00fatils per a guardar provisions, com ara: l’aigua, els llegums, les fruites, etc. at\u00e8s que evitaven que es fes malb\u00e9 el menjar.<\/p>\nLLOC D’ORIGEN<\/h6>\n
