Txoj Kev 1 ntawm 3: Saib Xyuas Lub Cev Muaj Zog
Kauj Ruam 1. Ua tib zoo saib cov xim
Txawm hais tias kub thiab tooj dag muaj xim zoo ib yam, cov hlau kub yog ci ntau dua thiab daj dua li tooj dag. Cov tooj dag hlau yog xim daj thiab tsis muaj xim daj ntawm cov xim dawb. Txawm li cas los xij, thaum kub tau sib xyaw nrog lwm cov hlau, txoj hauv kev no tsis tshua ntseeg tau.
Kauj Ruam 2. Txhuam cov hlau hla cov nplais ceramic
Kub yog hlau mos heev. Thaum txhuam rau ntawm cov nplais, kub yuav tawm ntawm lub cim kub. Ntawm qhov tod tes, tooj dag yog qhov nyuaj dua thiab yuav tso cov xim dub rau ntawm qhov chaw. Cias nias cov hlau tawm tsam cov ceramic thiab rub raws nws saum npoo.
Kauj Ruam 3. Kev ntsuas hlau ntom ntom
Txoj hauv kev raug tshaj plaws los ntsuas qhov ntom ntawm cov hlau yog ntsuas nws qhov ntim thiab qhov hnyav, thiab tom qab ntawd suav qhov ntom ntom. Hmoov zoo, muaj txoj hauv kev nrawm dua thiab yooj yim dua. Pov cov hlau me me nrog koj txhais tes, thiab cia nws poob (lossis, koj tseem tuaj yeem nqa cov hlau thiab txo qis nws yam tsis tas tawm ntawm koj txhais tes). Vim tias kub hnyav dua li tooj dag, nws hnyav dua qhov koj xav tau. Cov tooj dag yuav hnov sib zog vim nws qhov qis dua.
Txoj Kev 2 ntawm 3: Txheeb Xyuas Qhov Sib Txawv Ntawm Kev Lag Luam
Kauj Ruam 1. Saib hlau xeb
Carat yog chav rau ntsuas qhov dawb huv ntawm kub. Qhov siab dua qhov sib piv ntawm cov kub rau lwm cov hlau hauv cov khoom, qhov siab dua cov karat. Ntshiab kub muaj 24 carats. Cov hlau tooj dag yuav tsis muab rau ib chav uas hnyav. Feem ntau, xeb tau teev nyob rau hauv qhov chaw tsis meej, xws li hauv qab lossis sab hauv ntawm ib yam khoom, txawm hais tias qee zaum nws yuav nyob rau lwm qhov.

Kauj Ruam 3. Paub tus nqi ntawm cov hlau
Yog tias koj paub tus nqi muag ntawm cov hlau, koj tuaj yeem yooj yim qhia qhov sib txawv ntawm kub thiab tooj dag. Kub muaj tus nqi siab, nyob ntawm nws qhov kev dawb huv. Cov tooj dag yog pheej yig heev piv rau cov hlau muaj txiaj ntsig zoo li kub thiab nyiaj.
Txoj Kev 3 ntawm 3: Kuaj Cov Khoom Siv Tshuaj ntawm Cov Hlau
Kauj Ruam 1. Luam theej duab thaj chaw
Ib qho ntawm cov khoom muaj txiaj ntsig tshaj plaws ntawm kub yog tias nws tsis ua kom puas. Ntawm qhov tod tes, tooj dag reacts nrog oxygen hauv cov pa. Qhov tshuaj tiv thaiv no hu ua oxidation thiab yuav ua rau tooj dag pom muaj xim thiab xim tsis zoo. Yog tias muaj thaj chaw oxidized, nws txhais tau tias cov hlau yog tooj dag. Txawm li cas los xij, cov hlau tsis tas yuav kub txawm tias tsis muaj kab ntawm oxidation.
Kauj Ruam 2. Kuaj hauv thaj chaw uas tsis paub meej
Thaum kuaj cov tshuaj lom neeg ntawm cov hlau, nws yog qhov zoo tshaj los ua li ntawd hauv thaj chaw uas tsis pom. Qhov no ua kom ntseeg tau tias cov hlau tsis raug puas tsuaj los ntawm kev sim. Peb pom zoo xaiv daim di ncauj lossis tus nplaig ntawm ib yam khoom uas muaj sab hauv qab, lossis ib feem hlau uas raug kaw lossis zais.
Kauj Ruam 3. Thov kua qaub rau cov hlau
Siv cov kua qaub uas muaj zog rau cov hlau. Cov tooj dag yuav cuam tshuam nrog cov kua qaub, tsis zoo li kub. Yog tias koj pom cov npuas lossis xim daj thaum cov hlau tsoo cov kua qaub, nws txhais tau tias cov hlau yog tooj dag. Yog tsis muaj dab tsi hloov pauv, koj cov hlau yog kub.
Ceeb toom
- Cov kua qaub yog corrosive heev thiab acidic.
- Kev thov cov kua qaub rau hlau tuaj yeem txo tus nqi hlau.
