 Hauv lub neej, peb niaj hnub siv txhua yam khoom iav, xws li cov iav qhov rais, khob khob, qhov rooj zawv zawg qhov rooj thiab lwm yam. Cov tshuaj iav yog ob qho tib si zoo nkauj thiab ua tau zoo, thiab lawv muaj peev xwm ua kom siv lawv cov duab ntxoo-ua kom pom tseeb thiab ua kom tiav lawv lub zog thiab ruaj khov lub cev. Qee daim iav yuav ua rau iav muaj ntau cov qauv los txhim kho cov hniav zoo nkauj. Nyob rau hauv tsab xov xwm no peb yuav qhia seb lub khob fwj ua li cas thiab cov khoom siv tshuaj iav yog dab tsi. Ua ntej, li cas yog lub iav npias lub raj mis ua? Lub raj mis iav qhuav tsuas yog: 1 raw khoom siv ua ntej. Tej khoom siv (quartz sand, soda tshauv, limestone, feldspar, thiab lwm yam) yog muab cov khoom ntub ziab los ua kom qhuav, thiab cov khoom hlau uas muaj iron-iron yog raug tshem tawm cov tshuaj tua kab mob kom zoo zoo ntawm cov iav. 2 npaj kev npaj. 3 melting. Cov khoom siv iav ua kom sov siab (1550 ~ 1600 degrees) hauv lub pas dej ua ke los yog ib lub cub tawg uas ua rau lub khob iav uas yog lub cev, dawb ntawm cov npuas thiab ua raws li qhov yuav tsum tau ua. 4 molding. Cov iav kua yog muab tso rau hauv ib qho pwm tsim lub iav khoom ntawm ib yam khoom zoo li lub plhaub taum, cov tais diav ntau, thiab cov zoo li. 5 tshav kub kho. Los ntawm cov txheej txheem ntawm kev sib ntxub, quenching, thiab lwm yam., Kev ntxhov siab, sib cais sib cais los yog crystallization hauv lub khob yog tshem tawm los yog generated, thiab lub xeev ntawm cov iav hloov. |
