Ufa wa talc ndi chinthu chopangidwa m'mafakitale. Ndi talc ya magnesium silicate ya gulu la talc. Gawo lalikulu ndi aqueous magnesium silicate. Pambuyo pouphwanya, umatsukidwa ndi hydrochloric acid, kutsukidwa ndi madzi ndikuumitsa.
Ufa wa talc uli ndi zinthu zabwino kwambiri monga mafuta, kukana moto, kukana asidi, kutchinjiriza, kusungunuka kwambiri, mankhwala osagwira ntchito, mphamvu yabwino yophimba, kufewa, kunyezimira bwino komanso kulowetsedwa kwamphamvu.
Ufa wa talc nthawi zambiri umagwiritsidwa ntchito ngati chodzaza zinthu za pulasitiki ndi mapepala, chodzaza rabara ndi choletsa kumatira zinthu za rabara, utoto wapamwamba, ndi zina zotero.

Talc ili ndi zinthu zabwino kwambiri zakuthupi ndi zamakemikolo monga mafuta okhuthala, oletsa kumatira, thandizo la kuyenda kwa madzi, okana moto, okana asidi, oteteza kutentha, osungunuka kwambiri, osakhala ndi mphamvu ya mankhwala, oteteza kutentha bwino, ofewa, onyezimira bwino, komanso oletsa kulowetsedwa kwamphamvu. Chifukwa cha kapangidwe kake ka kristalo, talc imakhala ndi chizolowezi chogawanika mosavuta m'mamba ndi mafuta apadera. Ngati kuchuluka kwa Fe2O3 kuli kokwera, imachepetsa kutentha kwake.
