Crystal Glass thiab Nws Qhov Txawv nrog Ordinary Glass hauv Kev Ua Hniav Nyiaj Hniav Kub
Hauv ntiaj teb cov hniav nyiaj hniav kub, kev xaiv cov ntaub ntawv siv cuam tshuam loj heev rau qhov zoo nkauj, qhov zoo, thiab kev ruaj khov ntawm cov khoom. Ob hom iav uas feem ntau pom hauv cov hniav nyiaj hniav kub yog iav siv lead ua thiab iav ib txwm. Txawm hais tias ob hom no feem ntau zoo sib xws, muaj qhov sib txawv tseem ceeb uas ua rau iav siv lead ua zoo dua li iav ib txwm. Tsab xov xwm no yuav tshawb nrhiav iav siv lead ua kom tob, nws cov yam ntxwv, thiab nws txawv li cas ntawm iav ib txwm hauv cov ntsiab lus ntawm kev ua hniav nyiaj hniav kub.
Crystal Glass yog dab tsi?
Cov iav siv lead ua yog ib hom iav ua los ntawm silicon dioxide (SiO2) nrog rau kev ntxiv cov hlau oxides, feem ntau yog tin oxide (PbO). Feem pua ntawm tin oxide hauv cov iav siv lead ua cuam tshuam rau nws qhov zoo ntawm qhov muag, ua rau nws pom tseeb dua thiab muab qhov ci ntsa iab tshwj xeeb. Cov tin oxide no pab txhawb rau kev nce qib ntawm cov iav siv lead ua, yog li ntxiv cov luster thiab kev cuam tshuam lub teeb siab dua piv rau cov iav ib txwm muaj.
Keeb Kwm ntawm Crystal Glass
Kev tsim cov iav siv lead ua thawj zaug pib thaum xyoo pua 17th hauv Venice, Ltalis. Cov neeg ua haujlwm iav Murano tau tsim cov txheej txheem ua iav tshiab, tsim cov khoom uas muaj qhov meej thiab ci ntsa iab tsis tau muaj dua. Hauv xyoo pua 18th, Askiv tau qhia txog ib hom siv lead ua hu ua "lead crystal," ib lub khob uas muaj silicon dioxide, soda (sodium carbonate lossis potassium carbonate), thiab tin oxide.
Cov yam ntxwv ntawm Crystal Glass hauv kev ua hniav nyiaj hniav kub
1. Kev Pom Tseeb thiab Kev Ci Ntxim
Ib qho ntawm cov yam ntxwv ntawm cov iav siv lead ua yog nws qib siab tshaj plaws ntawm kev meej. Cov ntsiab lus tin oxide ua rau cov iav siv lead ua pob tshab thiab ci ntsa iab. Thaum lub teeb ntaus rau ntawm qhov chaw ntawm cov iav siv lead ua, nws cuam tshuam rau hauv txoj kev uas tsim cov ci ntsa iab zoo nkauj, ci ntsa iab. Qhov no tseem ceeb heev hauv kev ua hniav nyiaj hniav kub vim tias cov iav siv lead ua tuaj yeem ntxiv qhov ci ntsa iab thiab ci ntsa iab, ua rau nws zoo nkauj dua thiab zoo nkauj dua.
2. Kev ruaj khov
Cov tin oxide hauv cov iav siv lead ua kuj ua lub luag haujlwm hauv kev ua kom nws lub zog ntxiv. Cov iav siv lead ua feem ntau tiv taus khawb thiab cuam tshuam ntau dua li cov iav ib txwm muaj. Qhov kev ruaj khov no yog qhov tseem ceeb rau cov hniav nyiaj hniav kub uas muaj kev sib cuag ntau zaus, txawm tias thaum hnav lossis khaws cia.
3. Cov Ntsuas Refractive Siab
Cov iav siv lead ua muaj qhov ntsuas refractive siab dua li cov iav ib txwm. Qhov ntsuas refractive yog qhov ntsuas ntawm qhov kaj ntau npaum li cas refracted, lossis khoov, thaum nws hla dhau cov khoom siv. Qhov siab dua qhov refractive index, qhov ntau dua ntawm cov khoom siv lub peev xwm los khoov lub teeb thiab tsim cov teeb ci ntsa iab. Qhov no ua rau cov iav siv lead ua yog qhov kev xaiv zoo meej rau cov hniav nyiaj hniav kub uas tsim los ua kom pom tseeb sparkle thiab khoom kim heev.
Qhov Sib Txawv Ntawm Crystal Glass Thiab Ordinary Glass
1. Cov Tshuaj Lom Zem
Cov iav ib txwm muaj peb yam tseem ceeb: silicon dioxide, soda (sodium carbonate), thiab lime (calcium carbonate). Cov iav siv lead ua, ntawm qhov tod tes, muaj silicon dioxide tab sis ntxiv tin oxide. Qhov muaj tin oxide tsis yog tsuas yog txhim kho qhov meej xwb tab sis kuj ua rau cov iav siv lead ua ci ntsa iab dua.
2. Txheej Txheem Tsim Khoom
Feem ntau cov iav zoo tib yam raug tsim ntau heev nrog tus nqi qis dua, thaum cov iav siv lead ua yuav tsum muaj cov txheej txheem tsim khoom nyuaj dua thiab kim dua. Cov iav siv lead ua feem ntau xav tau cov txheej txheem tshwj xeeb xws li kev txiav thiab sib tsoo kom raug kom ua tiav cov nyhuv pom kev zoo.
3. Kev Pom Kev thiab Kev Zoo Nkauj
Saib ntawm qhov muag, cov iav siv lead ua feem ntau muaj qhov ci ntsa iab dua li cov iav ib txwm. Cov teebmeem pom kev uas cov iav siv lead ua tsim ua rau muaj kev ua si ntawm lub teeb pom kev zoo dua, ntxiv qhov zoo nkauj rau cov hniav nyiaj hniav kub. Cov hniav nyiaj hniav kub ua los ntawm cov iav ib txwm, txawm tias tseem zoo nkauj, feem ntau tsis muaj qhov ci ntsa iab thiab meej ib yam li cov iav siv lead ua.
4. Tus nqi thiab tus nqi
Vim nws txoj kev tsim khoom nyuaj thiab zoo dua, cov iav siv lead ua feem ntau kim dua li cov iav ib txwm. Qhov no kuj txhais tau tias cov hniav nyiaj hniav kub ua los ntawm cov iav siv lead ua feem ntau suav tias muaj nqis thiab tshwj xeeb dua, yog li ua rau tus neeg hnav lub koob npe nrov dua.
Siv Crystal Glass thiab Ordinary Glass hauv Cov Hniav Nyiaj Hniav Kub
Cov iav siv lead ua
Hauv cov hniav nyiaj hniav kub, cov iav siv lead ua feem ntau siv los tsim ntau yam khoom xws li cov hlua tes, cov hlua tes, cov pob ntseg, thiab cov nplhaib. Swarovski siv lead ua, ib lub npe nrov ntawm cov iav siv lead ua, feem ntau siv rau hauv cov hniav nyiaj hniav kub zoo nkauj vim lawv qhov meej thiab ci ntsa iab tsis sib xws. Tsis tas li ntawd, cov iav siv lead ua feem ntau siv rau hauv kev tsim cov pob zeb siv lead ua, cov pendants, thiab lwm yam hniav nyiaj hniav kub uas xav tau lub teeb ci ntsa iab tshaj plaws rau qhov zoo nkauj thiab zoo nkauj.
Iav Ib Txwm
Cov iav zoo tib yam kuj siv rau hauv cov hniav nyiaj hniav kub, tab sis feem ntau ntawm qib yooj yim dua thiab pheej yig dua. Cov hniav nyiaj hniav kub ua los ntawm cov iav zoo tib yam muaj qhov zoo nkauj yooj yim dua thiab tsis ci ntsa iab lossis zoo nkauj npaum li siv lead ua. Txawm li cas los xij, cov iav zoo tib yam tseem muaj nws qhov chaw hauv kev lag luam hniav nyiaj hniav kub, tshwj xeeb tshaj yog rau cov qauv tsim yooj yim dua thiab cov khoom siv niaj hnub uas tsis xav tau qhov ci ntsa iab ntau dhau.
Xaus
Ob qho tib si siv lead ua thiab iav ib txwm muaj lawv qhov chaw hauv kev lag luam hniav nyiaj hniav kub, tab sis qhov sib txawv tseem ceeb yog qhov zoo ntawm qhov muag, cov txheej txheem tsim khoom, thiab tus nqi zoo nkauj. Crystal iav, nrog nws qhov pom tseeb siab, ci ntsa iab, thiab ruaj khov zoo dua, yog qhov tsim nyog dua rau cov hniav nyiaj hniav kub khoom kim heev thiab tshwj xeeb. Ntawm qhov tod tes, iav ib txwm muaj kev xaiv pheej yig dua thiab siv tau rau cov qauv hniav nyiaj hniav kub yooj yim dua thiab yooj yim dua.
Kev xaiv ntawm cov siv lead ua thiab cov iav ib txwm yuav tsum raws li koj qhov xav tau tshwj xeeb thiab qhov zoo nkauj uas koj xav tau. Txawm li cas los xij, ob qho tib si tuaj yeem tsim cov hniav nyiaj hniav kub zoo nkauj thiab ntxim nyiam uas phim koj lub tswv yim thiab kev nyiam tsim.
