Txheej txheem cej luam iav thiab siv lead ua
Ua ntej delving mus rau hauv qhov tseem ceeb sib txawv ntawm siv lead ua thiab iav, nws yog ib qho tseem ceeb rau thawj zaug txhais seb lawv txhais li cas nyob rau hauv nrov kab lis kev cai. Rau cov neeg pib, feem ntau cov neeg tsis paub hais tias "Crystal" ua tau yog hais txog "ua iav." Hauv qab no yog ib qho kev ceev cov tshuaj lom neeg tshuaj coj los sib xyaw nrog rau ntau hom iav thiab siv lead ua uas tuaj yeem tshawb pom hauv lub khw.
Tsom iav
Tsom iav yog ntim uas tsim los siv cov iav. Lub sij hawm no feem ntau siv rau kev haus dej haus cawv uas tej zaum yuav yog lossis tsis muaj kev saib xyuas. Cov iav, raws li cov khoom siv raw, feem ntau yog hais txog cov dej qab-kua txiv, uas ua rau ntau tshaj 90 feem pua ntawm tag nrho cov iav uas yog hnub no. Hauv qab no yog ib qho kev qhia luv luv ntawm cov tshuaj lom neeg muaj pes tsawg leeg ntawm ntau hom tsom iav.
Dej qab zib dej qab zib
Dej kua txiv iav yog tsim los ntawm txiv qaub, dej qab zib, thiab silica. Qhov no yog qhov zoo tshaj plaws ntawm iav rau lub teeb qij, qhov rais, cov khoom ntim khoom, thiab cov duab kos, thiab lwm cov. Vim hais tias nws lub Cheebtsam yog muaj nyob rau hauv qhov, nws kuj yog feem ntau pheej yig.
Borosilicate iav
Borosilicate iav, los yog Pyrex, yog tsim los ntawm silica, boric acid, dej qab zib, thiab lwm yam khoom siv. Hom khob no feem ntau siv rau hauv kev kuaj thiab chav ua noj vim nws yog corrosion- thiab heat-resistant.
Fused Quartz
Fused quartz iav yog tsim los ntawm melting organic quartz muaju nyob rau hauv high temperatures. Hom iav no feem ntau yog siv rau cov cuab yeej siv kuaj, roj teeb, thiab cov koob yees duab high-end.
Crystal
Thaum neeg tuaj yeem tham txog kev nqa cov "Crystal," lawv feem ntau hais txog hom iav uas yog tsim los ntawm silica, lead oxide, soda lossis potash, thiab lwm yam khoom siv. Lead lead yog prized rau nws durability thiab hniav khoom, txawm tias nws tsis tas muaj ib cov qauv crystalline. Nws yog hu ua Crystal vim hais tias, xyoo dhau los, lub sij hawm Italian siv "cristallo" tau siv rau Murano glass imitations. Lead crystal yog hom uas feem ntau yog siv rau cov iav dej cawv thiab lwm yam khoom zoo nkauj nyob hauv tsev. Hauv Teb Chaws Asmeskas, tsom iav nrog cov hmoov txhuas ua ke ntawm 1 feem pua yeej raug categorized li siv lead ua. Hauv Tebchaws Europe, nyob rau lwm qhov, siv lead ua raws li iav nrog cov hlau lead uas yog 10 mus rau 30 feem pua.
Tshem Tawm Ntawm Cov Tsom Iav thiab Siv Kaw
Ib sab ntawm cov tshuaj lom neeg muaj pes tsawg leeg, uas tsis pom tseeb ntawm ib nrais muag, muaj ntau txoj hau kev los xyuas seb puas los yog tsis haus cawv ua los ntawm iav los yog siv lead ua los ntawm kev soj ntsuam. Cov npe hauv qab no yog qee yam tseem ceeb ntawm cov ntaub ntawv no ob.
Thickness
Piv rau iav, nplua nuj siv tau thinner los yog ntau zoo nkauj vim cov hlau lead ntsiab lus txo kev ua haujlwm ntawm lub khob, ua kom yooj yim rau sculpt. Nquag, iav tau raug rho tawm haujlwm kub siab vim tsuas muaj lub qhov rai luv luv rau lub sij hawm los tshuab lossis pwm. Muaj cov taug txhuas ua kom txo tau qhov kub thiab ncua sijhawm ua haujlwm, uas siv lead ua kom ntau dua ornate zoo nkauj piv rau iav. Txawm li cas los xij, thaum muaj cov hmoov txhuas nyob rau hauv qhov kev xav tau, nws kuj ua rau lub pob txha siv zog ua kom yooj yim dua, tawg, thiab khaus khawb.
Clarity
Tsom iav, tshwj xeeb tshaj yog cov uas tau ua los ntawm dej qab-kua txiv, yog pos huab thaum tab tom tawm tsam lub teeb. Crystal, ntawm qhov tod tes, paub txog nws cov clarity. Qhov no yog vim li cas siv lead ua yog qhov kev xaiv nrov tshaj plaws rau chandeliers, hniav nyiaj hniav kub, thiab qia paj hlwb. Rau cov neeg nyiam haus caw, siv lead ua los ntawm iav vim crystal drinkware pub rau kev yooj yim rau xim thiab viscosity ntawm cov kua. Cov txheej txheem qis dua hauv cov lead ua, ntau dua qhov tseeb.
Txhuam
Zoo ib yam li clarity, qhov Crystal's refractive quality kuj muaj kev sib txuas lus nrog nws cov ntsiab lus tseem ceeb. Siv lead ua kom zoo, tshwj xeeb tshaj yog yog tias nws muaj ib cov hlau lead uas muaj txij li 36 mus rau 70 feem pua, cov taws nyob rau hauv tshav ntuj. Qhov siv lead ua kom pom meej, lwm hom uas muaj taug txhuas, mus ntxiv ib kauj ruam ntxiv thiab polished mus txog rau thaum nws tsis muaj blemish- thiab distortion-dawb.
