Pendi inodziya zvakanyanya inogona kutsungirira kupisa kwakanyanya uye ngura. Indasitiri yekuputira inopisa zvakanyanya mu100℃-1800℃, pendi zhinji dzinodziya zvakanyanya dzinoshandisa mhinduro inodziya zvakanyanya, zvinodiwa nependi munzvimbo zvinogona kuita kuti ive nehunhu hwakagadzikana (hapana kudonha, hapana bubble, hapana kutsemuka, hapana hupfu, hapana ngura, inobvumira kutsvuka kudiki). Kusarudzwa kwakajairika kwesirivha kana dema, mavara maviri aya akagadzikana, haasi nyore kupera kana tembiricha yakakwira. Titanium dioxide ine kugadzikana kwakanaka kwekupisa, inodzivirira tembiricha 350-400℃ isingachinje ruvara uye 600℃ inoshanduka kuita brown, kusvika 1200℃ kusvika 1300℃ inova brown yakasviba isingadzoreki.
Kudzivirira kupisa kwe zinc oxide mu pigment chena kuri pakati pe 250 ne 300℃, lithopone yakakodzera kupisa kwenguva refu pa 250℃.
Mu pigment nhema, kupisa kwenguva refu kunoiswa kune kabhoni nhema pa250℃, kana tembiricha iri pamusoro pe300℃, ruvara runopera. Kuramba kupisa kwenguva refu kweupfu hwegraphite nemanganese dioxide kwe300℃.
Pigment tsvuku iri mu red iron oxide ne cadmium tsvuku ye 250℃ kana ichipisa kwenguva refu.
Cadmium strontium yeyero, yeyero uye yeyero inogona kutsungirira kupisa kwakanyanya kwenguva refu kwe200℃ chete.
