Ifu ya Talc ni ikintu gikorerwa mu nganda. Ni talc y'ubwoko bwa magnesium silicate. Igice cy'ingenzi ni magnesium silicate y'amazi. Iyo imaze gusya, ivurwa na aside hydrochloric, ikagezwa n'amazi hanyuma ikayumishwa.
Ifu ya Talc ifite imiterere myiza cyane ya fiziki na shimi nko gushonga, kurwanya umuriro, kurwanya aside, gukingira, gushonga cyane, shimi idakora, imbaraga nziza zo gutwikira, ubworoherane, ubwiza bwiza no gukurura cyane.
Ifu ya Talc ikunze gukoreshwa nk'iyuzuza ibikoresho bya pulasitiki n'impapuro, iyuzuza rubber n'iy'uburinzi bw'ibicuruzwa bya rubber, irangi ryiza cyane, nibindi.

Talc ifite imiterere myiza cyane ya fiziki n'iya shimi nko kuba ifite amavuta, irwanya gufatana, ifasha amazi gutemba, irwanya umuriro, irwanya aside, irinda gushonga, aho ishongesha cyane, ifite imiterere ya shimi idakora, ifite imbaraga zo gutwikira neza, yoroshye, irabagirana neza, kandi ikagira ubushobozi bwo gushonga cyane. Bitewe n'imiterere yayo ya kristu, talc ifite imiterere yo kugabanywamo ibice byoroshye n'ubushobozi bwihariye bwo gushonga. Iyo ingano ya Fe2O3 ari nyinshi, izagabanya ubushobozi bwayo bwo gushonga.
