Ihlukaniswe ngezigaba ezintathu: iqinile, ephakathi nendawo kanye nenemininingwane. I-mesh eqinile ibomvu omnyama, i-mesh ephakathi ibomvu kancane, kanti i-mesh encane ibomvu futhi imhlophe. Usayizi wezinhlamvu ze-mesh ngayinye uyafana, futhi ukuma kwezinhlamvu kuyafana. Ibizwa ngokuthi i-angular crystal enemiphetho ebukhali kanye namandla okugaya aphezulu.

Ukugaya imabula nezinye izinto ezithambile embonini yamatshe.

Ama-glass burrs embonini yengilazi, amashubhu ezithombe zethelevishini, amathuluzi okukhanya, amalensi, ama-prism, ingilazi yewashi, njll.

Ukuqhuma kwesihlabathi kwezimboni zensimbi, ukususa uthuli, ukugaya. Imboni yokunyathelisa igaya ipuleti eliyi-offset, kanti imboni yokukhanya icubungula isampula yepulasitiki, isikhumba, iphepha lokusanta nokunye ukusetshenziswa.

Amandla okugaya e-corundum yemvelo aphansi kancane kune-corundum emhlophe yesithando sikagesi, kodwa ukuqina kwayo kunamandla, futhi inezici zengxenye efana negobolondo. Izinzuzo zayo ukushelela okuphezulu kwezingxenye zokugaya, amamaki esihlabathi amancane nangaphansi. Ubuso bokugaya buhle futhi buyafana, okungathuthukisa ikhwalithi yomkhiqizo, okuyisici esiyingqayizivele salo mkhiqizo. I-emery yemvelo inesikhathi esifushane sokugaya, ukusebenza kahle okuphezulu kanye nentengo ephansi, okungenza kube nokuntuleka kokuphila kwenkonzo okufushane.
