Thaum kuv tseem yog menyuam yaus, kuv muaj kev xav tshwj xeeb rau lub pov haum.Kuv nyiam lawv lub ntsej muag ci ntsa iab.
Tus kws qhia hais tias kub ib txwm ci.Kuv xav hais tias kuv xav tau txhua lub pov haum.
Lub pov haum, txhua tus ntxhais tsis muaj kev tawm tsam rau lawv.Tus ntxhais me nyob hauv ib puag ncig tau dhau los ua kuv cov neeg siv khoom ncaj ncees.Lub sijhawm no, peb tau tso tawm cov khoom siv khawb lub pov haum, uas muaj ntau dua 15 lub pov haum ntuj tsis tshua muaj, nrog cov nqi sau ntau dua.Cia wb mus saib qhov tshwm sim tiag tiag ntawm lub pov haum:
Qhov tshwj xeeb ntawm cov khoom siv khawb lub pov haum no yog tias nws muaj 12 lub pov haum ruaj khov ntxiv rau 3-5 random gems.Tus naj npawb ntawm lub pov haum uas tiag tiag ncav cuag cov neeg siv khoom yog 15-17.
Qhov no tsis tsuas yog ua rau cov khoom siv khawb pob zeb nthuav dav ntxiv, tab sis kuj ua rau cov menyuam yaus xav tsis thoob.
Hais txog gems:
3 hom agate nrog cov xim sib txawv:agate yog ib hom ntawm chalcedony ntxhia, uas feem ntau yog ib qho thaiv thaiv nrog opal thiab cryptocrystalline quartz.Lub hardness yog 7-7.5 degrees, qhov kev faib ua feem yog 2.65, thiab xim yog heev txheej.Muaj translucency los yog opacity.Nws yog feem ntau siv rau ornaments los yog txaus siab.Cov hlua ntawm cov pob agate feem ntau tuaj yeem pom hauv cov khoom lom zem thaum ub.Agate muaj ringed kab txaij ntawm ntau yam xim, thiab nws kev ntxhib los mos zoo li siv lead ua.Nws yog ilv yam tsis muaj impurities thiab muaj lub luster ntawm iav.Nws yog pob tshab lossis translucent hauv ntau txheej.Txhua txheej sib tshooj sib tshooj thiab muaj ntau yam qauv, xws li ripple, concentric, mottled, txheej, thiab lwm yam.
Ob hom amethysts: amethyst txhais tau tias "tsis qaug dej qaug cawv" hauv Greek thaum ub.Nyob rau hauv lub medieval paj huam ntawm Fabkis, Bacchus, tus vajtswv ntawm caw, ncuav siv lead ua nrog caw, uas nyuam qhuav yug los rau thawj pom ntawm liab doog.Amethyst, tseem hu ua Amethystos, los ntawm lub ntsiab lus ntawm "tsis qaug dej qaug cawv".Nws yog hais tias cov siv lead ua irrigated los ntawm caw los ntawm Bacchus yog Ameslikas tsim los ntawm ib tug ntxhais.Qee cov tsev neeg muaj koob muaj npe nyob sab Europe ntseeg tias Amethyst muaj lub hwj chim tsis meej los pab cov neeg hnav kom tau raws li txoj cai thiab lub hwj chim.
Obsidian: Nws yog ib lub pov haum dub, tseem hu ua "daj siv lead ua" thiab "shisheng pob zeb".Nws yog ib txwm tsim silicon dioxide, feem ntau yog dub.Obsidian tau hyped rau ze li kaum xyoo thiab tsis muaj keeb kwm cuab yeej cuab tam.
Tsov lub qhov muag: Tsov lub qhov muag, tseem hu ua tsov lub qhov muag pob zeb, yog ib hom lub pov haum nrog miv lub qhov muag nyhuv, feem ntau daj xim av, nrog lo lo ntxhuav zoo li lub teeb nyob rau hauv lub pov haum.Tiger lub qhov muag pob zeb yog ib qho ntawm ntau hom quartz.Lub pov haum no tuaj yeem ua los ntawm crocidolite fiber silicon rau pseudocrystal hloov.
Pyrite: Pyrite (FeS2) feem ntau yuam kev rau kub vim nws lub teeb tooj liab xim thiab ci xim hlau ci, yog li nws tseem hu ua "fool kub".Cov khoom xyaw feem ntau muaj cobalt, nickel thiab selenium, nrog NaCl hom siv lead ua qauv.Cov uas muaj tib yam muaj pes tsawg leeg tab sis koom nrog orthogonal (orthorhombic) siv lead ua yog hu ua dawb hlau ore.Kuj tseem muaj kab kawm cobalt, npib tsib xee, tooj liab, kub, selenium thiab lwm yam hauv cov khoom sib xyaw.Thaum cov ntsiab lus siab, nws tuaj yeem rov qab tau zoo thiab siv rau hauv cov txheej txheem ntawm sulfur extraction.
Lub cev gypsum ntawm lub pov haum khawb no yog ib puag ncig-phooj ywg gypsum, uas yuav tsis ua rau muaj kev phom sij rau cov neeg siv.
Cov cuab yeej siv hauv kev khawb kuj tseem ua tib zoo xaiv.
