Hauv qee thaj chaw, zoo li Ozarks ntawm Missouri, koj tuaj yeem pom chert dag thoob plaws hauv av. Qhov ntawd yog vim cov nplaim taws thiab cov ntoo tawv tawv, cov pob zeb ruaj khov uas tiv taus huab cua lawv tseem nyob tsis ntev tom qab cov pob zeb nyob ib puag ncig tau ya mus rau hauv av.
- Koj tuaj yeem tshawb nrhiav raws ntug dej hiav txwv lossis dej ntws. Flint yog qhov ruaj khov thiab tiv taus cov tshuaj, yog li nws feem ntau sau hauv cov av uas seem li ib puag ncig cov pob zeb carbonate nyob ib puag ncig. Thaum cov pob zeb zoo li limestone yaig thiab av zoo raug nqes mus rau hauv qab, cov pob zeb me me tso ntawm cov nplais thiab chert sau raws ntug dej hiav txwv.
- Sim lwm qhov chaw uas muaj ntau yam pob zeb tam sim no, xws li kev tsim kho lossis raws txoj kev pob zeb. Ntau zaus cov pob zeb tau sau los ntawm cov hav dej rau kev tsim kho los ntawm thoob plaws, yog li koj yuav xav tsis thoob thaum pom cov pob zeb tawg lossis cov pob zeb tawg tsuas yog thaiv.
Kauj Ruam 2. Kawm keeb kwm ntawm koj cheeb tsam

- Lwm hom quartz los kawm paub txheeb xyuas uas tseem tuaj yeem siv ua qhov chaw ntawm cov nplaim hluav taws tuaj yeem yog carnelian, agate, bloodstone, jade thiab chalcedony.
- Cov pob zeb puag ncig tuaj yeem cuam tshuam qhov pom ntawm cov nplaim taws. Thaum cov nplaim paj tau muab faus rau hauv cov av nplaum, cov dawb patina lossis zaj duab xis tuaj yeem tsim ua cov nplaim taws.
Kauj Ruam 2. Nrhiav cov nplaim paj hauv ntau yam duab
Flint tuaj yeem pom nyob rau hauv qhov tshwm sim ntawm cov qog los yog ua ib qho tawg uas tau ua haujlwm zoo.
- Flint nodules tuaj yeem tshwm nyob rau hauv ntau yam du, sib npaug ua ke hauv chalk lossis limestone. Thaum koj pom cov nplaim taws uas tau ntxig rau hauv lub txaj chalk, nws ib txwm pom pom cov ntawv luam tawm ntawm lub plhaub rau hauv av.
- Nrhiav cov pob zeb uas tau muab faib zoo li iav tawg. Flint puas sib txawv ntawm ntau cov muaju. Thaum cov khoom los sib nrug zoo li zoo li iav iav, nrog txoj kab nkhaus thiab cov npoo zoo dua.
- Ntxiv rau kev saib rau ntuj pob zeb ntawm cov nplaim taws, nco ntsoov saib cov nplaim hluav taws uas tau ua haujlwm zoo lawm. Koj tuaj yeem tswj hwm txoj kev flint sib faib yooj yim dua li lwm lub pob zeb, uas yog lwm qhov laj thawj yog vim li cas tib neeg thiaj siv cov nplaim taws los tsim cov cuab yeej thiab riam phom. Qee zaum flint yuav muaj cov npoo uas zoo li tau chipped tam sim lossis muaj lub ntsiab lus, qhia tias lawv tau siv los ua cov cuab yeej.
Kauj Ruam 3. Nrhiav qhov ci ntsa iab ntawm lub pob zeb

- Thaum ntaus koj cov nplaim hlau, xyuas kom lub pob zeb qhuav, vim lub pob zeb ntub yuav tsis ua kom tawg.
- Lwm cov pob zeb, xws li quartz, uas muaj tawv tawv ntawm xya ntawm Mohs Nplai ntawm Kev Nyuaj Siab yuav tsim cov txim taws thaum ntaus tawm tsam cov pa roj carbon. Yog tias koj tsuas yog nrhiav lub pob zeb uas koj tuaj yeem siv los tsim cov txim taws thiab pib tua hluav taws, sim kawm seb lwm hom pob zeb twg tseem yuav ua txoj haujlwm.
