Izitsha zobumba ezipendiwe, ezaziwa nangokuthi izitsha zobumba ezipendiwe, ziyimisebenzi yobuciko yobumba enomlando omude. Kubhekiselwa ezitsheni zobumba ezipendwe phezulu ngemva kokushiswa kwesondo lobumba, ngokungafani nezitsha zobumba ezipendwe esitsheni sobumba, umbala nomzimba oluhlaza kuyacindezelwa ndawonye, ​​futhi i-faience iyosiwa ngokushisa okuphezulu, umbala wobumba obupendiwe. ayilandelwa ngokuqinile, futhi iphethini kulula ukuwa uma imanzi noma amanzi. Izitsha zobumba ezipendiwe zaqala ngasekupheleni kwenkathi ye-Neolithic, imibala evame ukusetshenziswa ibomvu, emnyama, ephuzi, emhlophe, e-ocher, njll., umbala muhle, ngoba umdwebo awusashiswa, ngakho-ke umdwebo kulula kakhulu ukuwugqoka nokuwa. .

Izitsha zobumba ezipendiwe ezenziwa okhokho basendulo zenziwe ngobumba obuphezulu be-alluvial ngasemfuleni, obuhlanzekile futhi obungenakho ukungcola, obuswakeme njengekhekhe elibomvana; futhi udaka lunokuguquguquka. Izitsha zobumba ezishisiwe zine-"glue" ukuthungwa uma zibukwa ngeso lenyama.
Ngenxa yezimo ezingezinhle zobuchwepheshe zokudubula ngaleso sikhathi, izinga lokushisa lokudubula laliphansi ngokuqhathaniswa, futhi izitsha zobumba ezishisiwe zazimunca amanzi aqinile. Ukuthinta umzimba ngesandla sakho kuzokwenza umsindo ongakhulumi ophansi; Ukuzizwa ulula ngesisindo lapho usebenzisa isandla sakho ukwenza izitsha zobumba; Akufanele kube nomuzwa onzima wokucindezela; Manisa izitsha zobumba ngamanzi, ungezwa iphunga elibi lenyama yomhlaba; Uma ubhekisisa kahle, kuzoba nezimbobo zezinaliti ezincane ebusweni bezitsha zobumba.
Izitsha zobumba zasendulo, iningi lazo okuyizitsha eziphilayo zamadlozi, ngaphambi kokungcwatshwa emhlabathini, umzimba womkhumbi unemikhondo yokushayisana, ukusetshenziswa komzimba isikhathi eside kunento yokugqoka yemvelo, futhi kukhona ukuxhumana nomoya, amanzi, amafutha nezinye izinto ezikhiqizwa "igobolondo lombala wokunamathisela". Izitsha zobumba ezipendiwe zingcwatshwe emhlabathini izinkulungwane zeminyaka, futhi ngemva kokuqoqwa kwesikhathi eside, ubuso bezitsha zobumba bugcwele "isikali". "Isikali" sangempela asikwazi ukugezwa ngamanzi, shayela "isikali" nge-dilute hydrochloric acid, uzobona "isikali" sikhipha intuthu emhlophe futhi igwebu.

Ngokuthuthuka kobuchwepheshe kanye nokuthuthukiswa kancane kancane kokuqwashisa komuntu ubuhle, abantu be-Neolithic kancane kancane baqala ukuhlobisa ngamabomu izitsha zobumba, ngakho kwaba nomsebenzi wobuciko onjenge-faience. Ukudweba kuyingxenye ebalulekile yokwenza i-faience. Okhokho benkathi ye-Neolithic bapenda amaphethini okuhlobisa ezingane, alula futhi amahle anesikhumba esinemibala ezikhaleni zobumba, ukuze izitsha zobumba ezejwayelekile zibe ubuciko bobuciko bangaphambi komlando obuyigugu ezandleni zababumbi.
