Qhov kev sib deev ncaj ncees tau suav tias yog tus nyiam tshaj plaws nyiam ntawm cov hniav nyiaj hniav kub txhua lub sijhawm. Ntshav kub, nrog nws cov tsos, ua rau muaj kev txaus siab rau lawv: cov hlau no muaj kuab heev thiab zoo nkauj, thiab hauv kev sib xyaw nrog cov pob zeb muaj nqi thiab lwm yam khoom siv, nws muab lub neej rau kev ua haujlwm zoo tshaj plaws ntawm cov hniav nyiaj hniav kub.
Keeb kwm ntawm ntshav kub
Cov lus hais txog ntshav kub ua ntej tau tshwm sim thaum lub sijhawm tshawb nrhiav keeb kwm ntawm Tut lub qhov ntxa hauv xyoo 1931. Ntau yam khoom sib txawv tau pom nyob hauv nws lub qhov ntxa, qee qhov ntawm lawv muaj qhov tsis xwm yeem xim txhawm rau. Lub sijhawm ntawd, ntau tus kws tshawb fawb thiab cov kws tshawb xyuas keeb kwm qub tau sim dhau qhov kev sib xyaw thiab cov khoom ntawm cov hlau los ntawm cov khoom lag luam ntawm kev zoo nkauj txawv txawv.
Cov lus qhia zais ntawm cov khoom siv txawv txawv tau tshwm sim tsuas yog tom qab ob peb xyoos. Nws yeej tsis tshwm sim rau leej twg tias txhuas zoo tib yam muab cov xim zoo nkauj heev rau hlau. Cov nta ntawm ntshav kub ua ntej tau piav qhia thawj zaug hauv nws txoj haujlwm kev tshawb fawb los ntawm American tus kws tshawb fawb - physicist Robert Wood. Tom qab ntawd, nws tsis tau tsum tsis tsum tsuas yog thaum qhia txog cov sib xyaw ntawm cov hlau nplaum: nws tus kheej tswj tau rov ua qee cov kev dai kom zoo nkauj uas pom hauv lub qhov ntxa ntawm Iyiv tus vaj ntxwv. Niaj hnub no, qee cov khoom no tau muab tso rau ntawm Lub Tsev khaws puav pheej Cairo.
Txoj kev tshawb fawb ntawm nws cov khoom tsis tau nres nkaus xwb ntawm qhov kev tshawb pom ntawm qhov kub kub xim. Cov khoom siv nyiam cov xim ntawm cov lus Askiv zoo tib yam metallurgist Roberts-Austen. Nws yog nws leej twg tswj kom paub qhov tseeb qhov sib npaug ntawm kub thiab txhuas, nrog rau ua tiav qhov ua kom pom tseeb ntawm cov xim hlau, uas pib zoo li ntau lub pob zeb diamond ntau dua li hlau. Raws li kev sim ntawm cov kws tshaj lij ntawm lub cev thiab kws yog hlau, cov qauv ntawm cov hlau tshiab muaj nqi kuj tau tsim - 750.
Qhov twg muaj cov ntshav kub yog thov
Kev siv cov xim kub xiav yog qhov tshwm sim heev hauv ntau yam lag luam. Nws yog siv los ntawm jewellers, ua rau ntau yam hniav nyiaj hniav kub. Tsis tas li, ntshav kub yog tau zoo siv los ntawm cov kws ua yeeb yam hauv lawv cov kev ua si muaj tswv yim, pleev duab ua haujlwm los ntawm cov plooj (veneers) rau lawv. Lwm qhov siv rau cov xim kub xaum tau pom los ntawm cov kws tshuaj, thaum lawv tswj los tsim cov tshuaj ntawm cov xim zoo ib yam ntawm lub hauv paus ntawm cov khoom siv hlau uas muaj nqi. Nws yog ntxiv rau iav yaj, ua rau cov khoom lag luam ruby-xim.
Dab tsi yog tus nqi ntawm cov ntshav kub
Txij li nws yog qhov nyuaj heev kom pom cov khoom ua los ntawm ntshav kub hauv ib lub khw muag khoom zoo nkauj, nws yog qhov nyuaj heev rau npe tus nqi pes tsawg ib gram ntawm cov hlau. Txog rau hnub tim, tsuas muaj ntaub ntawv hais tias cov hniav nyiaj hniav kub uas muaj hnyav 19 carats, inlaid nrog cov ntshav kub tso nrog, tau muag rau 55 txhiab daus las. Tus nqi no vim yog qhov kev nyuaj siab ntawm kev ua cov alloy, yog li ntawd, ntawm 750 purity ntawm ntshav kub, nws tus nqi ntau zaus ntau dua li ib txwm. Txawm li cas los xij, txawm tias tus nqi siab tsis tiv thaiv txoj kev loj hlob ntawm cov hlau no.
