Yepamusoro tembiricha pendi iyo inokwanisa kutsungirira yakanyanya tembiricha oxidation uye corrosion medium.Indasitiri yekupisa yekuputira yakakwira mune 100 ℃-1800 ℃, yakawanda yekupisa tembiricha pendi inoshandisa yakanyanya tembiricha mhinduro, pendi inodiwa munharaunda inogona kuwana yakagadzikana yemuviri zvivakwa (hapana kudururwa, hapana bubble, hapana kutsemuka, hapana hupfu, hapana ngura, bvumira kushanduka zvishoma).Kusarudzwa kwakawanda kwesirivheri kana dema, iwo mavara maviri akadzikama, kwete nyore kupera pakupisa kwakanyanya.Titanium dioxide ine yakanyanya kugadzikana yekupisa, tembiricha isingachinji 350-400 ℃ isingachinji ruvara uye 600 ℃ inoshanduka kuita tan, inosvika 1200 ℃ kusvika 1300 ℃ inova isingadzokeri yakasviba yakasviba.
Heat resistance ye zinc oxide mu white pigment i 250 kusvika 300 ℃, lithopone inokodzera kupisa kwenguva refu pa250 ℃.
Mune dema pigment, kupisa kwenguva refu kunoiswa kucarbon dema pa250 ℃, kana tembiricha iri pamusoro pe300 ℃, ruvara rwunopera.Iyo yekureba yekupisa kupisa kwegraphite poda uye manganese dioxide ye300 ℃.
Iyo dzvuku pigment mune tsvuku iron oxide uye cadmium tsvuku ye250 ℃ kana kwenguva refu kupisa.
Yero, yero uye yero cadmium strontium kwenguva yakareba tembiricha yakakwira inongokwanisa kumira 200 ℃.
