Yahlulahlulwe yangamacandelo amathathu: arhabaxa, aphakathi kwaye anenkcukacha.Umnatha orhabaxa umnyama obomvu, umnatha ophakathi ubomvu okhanyayo, kwaye umnatha ocolekileyo ubomvu namhlophe.Ubungakanani beenkozo zomnatha ngamnye bufana, kwaye ukumila kweenkozo kuyafana.Ibizwa ngokuba yikristale ye-angular enemiphetho ebukhali kunye namandla aphezulu okusila.

Ukugaya ibhastile kunye nezinye izinto ezithambileyo kushishino lwamatye.

Umzi-mveliso weglasi ucola iibhubhu zeglasi, iityhubhu zemifanekiso kamabonakude, izixhobo zamehlo, iilensi, iiprism, iglasi yewotshi, njl.

Ukuqhunyiswa kwesanti yesinyithi kwimizi-mveliso, ukudiliza, ukucola.Ishishini lokushicilela lisila i-offset plate, kwaye ishishini lokukhanya lisebenza isampuli yeplastiki, ufele, i-sandpaper kunye nokunye okusebenzisayo.

Amandla okusila e-corundum yendalo angaphantsi kancinci kunombane we-corundum emhlophe, kodwa ukuqina kwayo kunamandla, kwaye ineempawu zecandelo elifana neqokobhe.Iingenelo zayo kukuguda okuphezulu kweendawo zokusila, amanqaku amancinci kunye nesanti enzulu.Indawo yokugaya ilungile kwaye ifanayo, enokuphucula umgangatho wemveliso, eyona nto ikhethekileyo yalo mveliso.I-emery yendalo inexesha elifutshane lokugaya, ukusebenza okuphezulu kunye nexabiso eliphantsi, elinokuthi lenze ukunqongophala kobomi obufutshane benkonzo.
