Ko te wāhanga matua o te talc he konupora silicate kei roto te wai, ko te tātai ngota Mg3 [Si4O10] (OH) 2. Nō te pūnaha monoclinic te talc. He rite te āhua o te tioata ki ngā kongakonga hexagonal, rhombic rānei, e kitea ana i ētahi wā. I te nuinga o te wā ka hangaia hei puranga matotoru, he rite ki te rau, he radial, he muka hoki. Kāore he tae, he mā rānei, engari he āhua kakariki mārama, he kōwhai mārama, he parauri mārama, he whero mārama rānei nā te iti o ngā poke; He kanapa te mata o te wehenga. Te pakeketanga 1, te taumaha motuhake 2.7-2.8.

He tino pai ngā āhuatanga ā-tinana, ā-matū hoki o te pāreti pērā i te whakahinuhinu, te ārai piri, te āwhina rere, te ātete ahi, te ātete waikawa, te ārai wera, te teitei o te ira rewa, ngā āhuatanga matū kore mahi, te kaha hipoki pai, te ngawari, te kanapa pai, me te kaha mimiti. Nā tōna hanganga karaihe paparua, he ngāwari te wehewehe o te pāreti ki ngā unahi me te whakahinuhinu motuhake. Ki te nui te ihirangi o te Fe2O3, ka whakaitihia tōna ārai wera.

He ngohengohe te tāra, ko te tauwehenga pakeke Mohs he 1-1.5, ā, he ahua pahekeheke. He tino oti te tapahi {001}, ā, he ngāwari ki te pakaru hei poro angiangi. He iti te koki okiokinga tūturu (35 °~40 °), ā, he tino kore pumau. Ko te toka e karapoti ana he magnesite, he magnesite, he konganuku kikokore, he mapere dolomite rānei kua whakakīia ki te silicified me te pahekeheke. Haunga ētahi toka āhua pumau, he kore pumau te nuinga, me ngā hononga me ngā whati kua whanake. He pānga nui ngā āhuatanga ā-tinana me ngā āhuatanga ā-pūkaha o te konganuku me te toka e karapoti ana ki te tukanga keri.

Te taumata matū
Whakamahinga: Whakamahia hei whakakaha me te whakakī whakarerekē i roto i ngā ahumahi matū pēnei i te rapa, te kirihou, te peita, me ētahi atu. Ngā Āhuatanga: Ka whakanui ake i te pumau o te āhua o te hua, ka whakanui ake i te kaha kume, te kaha kutikuti, te kaha takai, te kaha pēhanga, ka whakaiti i te whakarerekētanga, te roa, te tauwehenga whānui wera, te mā teitei, me te kaha o te ōrite me te marara o te rahi matūriki.

Te karaehe uku
Whakamahinga: Whakamahia mō te hanga uku auau-teitei, uku ahokore, uku ahumahi, uku hoahoanga, uku o ia rā, me ngā paninga uku. Ngā Āhuatanga: Kāore e memeha te tae i te pāmahana teitei, he mā ake i muri i te hanga, he rite te matotoru, he kanapa pai, he mata maeneene.

Te kounga whakapaipai
Kaupapa: He mea whakakī kounga teitei i roto i te umanga whakapaipai. Ngā Āhuatanga: He nui te huānga silicon kei roto. He mahi tāna ki te aukati i ngā hihi infrared, ā, ka whakarei ake i te mahi ārai-rā me te ātete infrared o ngā whakapaipai.

Tohu hauora me te tohu kai
Te Whakamahinga: Whakamahia hei tāpiringa i roto i ngā ahumahi rongoā me te kai. Ngā Āhuatanga: Kāore he paitini, kāore he kakara, he mā te tae, he hototahi pai, he kanapa kaha, he ngawari te reka, ā, he maeneene kaha. Kāore te uara pH o te 7-9 e whakaiti i ngā āhuatanga o te hua taketake.

Te taumata pepa
Kaupapa: Whakamahia mō ngā hua ahumahi pepa kounga teitei, kounga iti hoki. Ngā Āhuatanga: Ko ngā āhuatanga o te paura pepa he mā te tae, he pumau te rahi o te matūriki, ā, he iti te pakaru. Ka taea e te pepa i hangaia ki tēnei paura te maeneene, te ātaahua, te penapena rauemi mata, me te whakapai ake i te roa o te mahi o te mata kapia.

Paura paru
Whakamahinga: Whakamahia mō te hanga porcelain hiko, porcelain hiko ahokore, ngā momo uku ahumahi, ngā uku hoahoanga, ngā uku o ia rā, me te paninga uku. Ngā Āhuatanga: Kāore e memeha te tae i te pāmahana teitei, he mā ake i muri i te hanga, he rite te matotoru, he kanapa pai, he maeneene te mata.
