Jecha rine mavara rava kupatsanurwa kuita jecha rine mavara echisikigo, jecha rine mavara akacheneswa, jecha rine mavara echinguvana uye jecha rine mavara echigarire. Hunhu hwaro ndehwekuti: ruvara rwakajeka, kuramba acid nealkali, kuramba UV, kusapera. Jecha rine mavara echisikigo: Rakagadzirwa nematombo echisikigo akapwanywa, asingatsvedzi asi ane tsvina yakawanda; Jecha rine mavara echinguvana: ruvara rwakajeka, nyore kubvisa ruvara.

Jecha rine ruvara rwechisikigo rinogadzirwa nematombo emarble kana granite kuburikidza nenzira dzakasiyana-siyana dzakadai sekusarudza, kupwanya, kupwanya, kuisa giredhi uye kurongedza.
Nzira yekuisa jecha rine ruvara rwakasiyana-siyana inoumbwa nematanho mana: kusanganisa, kupisa, kunyungudutsa uye kutonhora. Inoratidzwa nekuti: mumatanho ekupisa nekunyungudutsa, mhepo inopisa inopihwa nechoto chemhepo inopisa inoshandiswa kupisa nekunyungudutsa zvinhu zvakasanganiswa zviri mudhiramu rekupisa nekunyungudutsa.

Jecha rine ruvara rinodhayiwa nejecha re quartz rakatsetseka uye rine hunhu hwekusapera. Jecha rine ruvara rinogadzirisa zvakaipa zvejecha rine ruvara rwechisikigo, zvakaita seruvara rusina kupenya uye mhando shoma dzemavara. Ruvara rwacho rwakasimba, runogara kwenguva refu uye haruperi.
