Ko te "waro pitch", he whakarāpopototanga mō te "waro tar pitch", he mea tukatuka i te waro tāra i muri i te tango i te toenga wai tāra, nō te momo uku horihori, ko te tikanga he wai matotoru, he totoka-haurua, he totoka rānei, he mangu, he kanapa, ko te tikanga he 92~94% te waro, ā, tata ki te 4~5% te hauwai. Ko te waro tāra he hua nui i roto i te tukanga tukatuka waro tāra, ā, he rauemi mata kore e taea te whakakapi mō te hanga waro.
Ko te kaupapa o te whakatōtō tāra he whakakorikori i ngā matū he rite te kohua i roto i te tāra ki ngā wāhanga e rite ana hei tukatuka me te wehewehe i ngā hua monomer. Ko te toenga o te tangohanga whakatōtō ko te pitch tāra waro, e 50% ~ 60% o te tāra waro.
E ai ki ngā pūwāhi whakangawari rerekē, ka wehea te uku waro ki te uku pāmahana iti (uku ngohengohe), te uku pāmahana waenga (uku noa), te uku pāmahana teitei (uku mārō) e toru ngā wāhanga, kei ia wāhanga ngā tohu Nama 1 me te Nama 2 e rua.
Ko te nuinga o te wā ka whakamahia te uku waro i roto i ngā mara e whai ake nei:
* Wahie: Ka taea te whakaranu i ngā wāhanga totoka ki te hinu taumaha, ka hangaia rānei hei paru kua whakamahia, ka taea te whakakapi i te hinu taumaha.
Peita: He peita e tāpiri ana i te rōsin, te tāpenetini rānei me ngā whakakī i te tunu hinu mō ngā whare, ngā paipa rānei e ārai ana i te wai. He pai mō ngā hanganga maitai o waho, te paparanga ārai wai me te paparanga tiaki i te raima me te pereki, ā, ka taea te peita me te peita i te pāmahana rūma.
* Hanga rori, rauemi hanga: i te nuinga o te wā ka whakaranua ki te uku hinu, te uku waro me te uku hinu, he mārama te rerekētanga o te kounga me te pakari. He ngoikore te kirihou o te uku waro, he ngoikore te pumau o te pāmahana, he pakarukaru i te takurua, he ngawari i te raumati, ā, he tere te koroheketanga.
* Hononga: Mai i te hikohiko, te whakapiri anode me ētahi atu hua waro, ko te tikanga he uku kua whakarerekētia. Ko te tikanga, ka hangaia te uku kua whakarerekētia mai i te uku pāmahana-waenga. I Haina, ko te tikanga whakamahana i roto i te kettle te tikanga, ā, ka whakamahia te hau hei wahie hei whakamahana i te uku i roto i te tauhohenga. Hei whakamutunga, ka whiwhihia te uku kua whakarerekētia totoka mā te wehenga me te whakapūkara.
* Koka uku: he toenga totoka o te uku waro i muri i te whakahokinga pāmahana teitei, te whakaroa rānei i te tunu. He maha ngā wā ka whakamahia te koka uku hei rauemi mata mō ngā rauemi waro motuhake, he mea nui mō te hanga taputapu whakaputa haurua-ira me ngā taputapu whakaputa papa rā. He whānuitia te whakamahinga hei rauemi hiko mō te whakamahine konumohe, hei rauemi waro mō te hanga maitai oumu hiko, me te rauemi mata hua waro motuhake mō te haurua-ira.
* Koka ngira: he uku ngohengohe kua whakatikatikaina mā te tukatuka rauemi mata i mua, te koka whakaroa, te whakapūkara pāmahana teitei e toru ngā tukanga, e whakamahia ana i roto i te hanga hiko me ngā hua waro motuhake. Ko ngā hua i hangaia mai i ōna rauemi mata he iti te ātete, he iti te tauwehenga whānui wera, he kaha te ātete wera, he kaha miihini teitei me te ātete pai ki te waikura.
* Muka waro: muka motuhake he nui ake i te 92% te nui o te waro i riro mai i te uku mā te whakamahine, te miro, te whakahāora-mua, te whakahāngai waro, te whakakāwhata rānei.
* He mea hanga ki te huruhuru hipi, ki te waro whakahohe, ki te waro pango me ētahi atu whakamahinga.
