Kuchinjisa ndiyo nzira yekuenzanisa uye kuumba huwandu hwakasimba hwezvinhu nekupisa kana kudzvinyirira pasina kuungudza kusvika padanho re liquefaction.
Kuchinjisa kunobudirira kana maitiro acho achideredza porosity uye anowedzera zvivakwa zvakadai sesimba, magetsi ekuita, translucency uye inobata-famba. Munguva yekupfura, atomic kusiyana inotyaira powana yekubvisa matanho akasiyana, kutanga kubva pakuumbwa kwemitsipa pakati pePorders kuti apiwe pores pores.
Kuchinjisa ndechimwe chikamu chekupfura kunoshandiswa mune zve ceramic zvinhu, izvo zvinogadzirwa kubva pazvinhu zvakadai segirazi, zirconia, Gersia, lime, bersillium oxide, uye ferric oxide. Mamwe eCeramic anogadzira zvinhu zvine hukama hwakaderera hwemvura uye yakaderera eplasticity indekisi pane ivhu, inoda organic inowedzera mumatanho usati watchetesa.
