Yahlulwe yangamacandelo amathathu: irhabaxa, iphakathi kunye neneenkcukacha. I-mesh erhabaxa ibomvu omnyama, i-mesh ephakathi ibomvu kancinci, kwaye i-mesh ecolekileyo ibomvu namhlophe. Ubungakanani be-mesh nganye buyafana, kwaye imilo ye-grain iyafana. Ibizwa ngokuba yi-angular crystal enemiphetho ebukhali kunye namandla aphezulu okusila.

Ukugaya imabula kunye nezinye izinto ezithambileyo kushishino lwamatye.

Iiglasi ezigayiweyo kwishishini leglasi, iityhubhu zemifanekiso kamabonakude, izixhobo ze-optical, iilensi, iiprism, iglasi yewotshi, njl.njl.

Ukuqhumisa isanti kwimizi-mveliso yesinyithi, ukususa uthuli, ukugaya. Imizi-mveliso yokushicilela iqhekeza ipleyiti, kwaye ishishini lokukhanya licubungula isampuli yeplastiki, ulusu, iphepha lesanti, njl.njl.

Amandla okusila e-corundum yendalo aphantsi kancinci kune-corundum emhlophe yesithando sombane, kodwa ukuqina kwayo kunamandla, kwaye ineempawu ezifana neqokobhe. Iingenelo zayo kukuba iindawo zokusila zithambile, amabala esanti amancinci nangaphantsi. Umphezulu wokusila ulungile kwaye uyafana, nto leyo enokuphucula umgangatho wemveliso, oluphawu olulodwa lwale mveliso. I-emery yendalo inexesha elifutshane lokusila, ukusebenza kakuhle kunye nexabiso eliphantsi, elinokuhlawula ukunqongophala kobomi benkonzo obufutshane.
