Nkiri umwana, numvaga bidasanzwe kumabuye y'agaciro.Nakunze isura yabo itangaje.
Umwarimu yavuze ko zahabu ihora imurika.Ndashaka kuvuga ko nshaka amabuye y'agaciro yose.
Amabuye y'agaciro, umukobwa wese ntabarwanya.Umukobwa muto mubaturanyi yabaye umukiriya wanjye wizerwa.Iki gihe, twasohoye ibikoresho byo gucukura amabuye y'agaciro, arimo amabuye y'agaciro arenga 15 adasanzwe, hamwe nagaciro gakusanyirijwe hamwe.Reka turebe isura nyayo yamabuye y'agaciro:
Umwihariko wiki gikoresho cyo gucukura amabuye y'agaciro ni uko gifite amabuye 12 yagenwe hiyongereyeho 3-5 y'agaciro.Umubare w'amabuye y'agaciro agera kubakiriya ni 15-17.
Ibi ntibituma gusa ibikoresho byo gucukura amabuye y'agaciro birushaho gushimisha, ariko kandi biha abana gutungurwa gutunguranye.
Ibyerekeye amabuye y'agaciro:
Ubwoko 3 bwa agates hamwe namabara atandukanye:agate ni ubwoko bwa minisiteri ya chalcedony, akenshi ikaba ari bande ihujwe ivanze na opal na cryptocrystalline quartz.Ubukomezi ni dogere 7-7.5, igipimo ni 2,65, kandi ibara ryuzuye.Kugira ibintu bisobanutse cyangwa bidasobanutse.Bikunze gukoreshwa kumitako cyangwa gushima.Imirongo yimipira ya agate irashobora kugaragara mubintu byo gushyingura kera.Agate yazunguye imirongo y'amabara atandukanye, kandi imiterere yayo ni nka kristu.Nibyoroshye bitagira umwanda kandi bifite urumuri rwikirahure.Irasobanutse cyangwa irasobanutse mubice byinshi.Buri cyiciro cyuzuzanya kandi gifite ubwoko bwinshi bwibishushanyo, nka ripple, concentric, mottled, layer, nibindi.
Amethysts ebyiri zitandukanye: amethyst bisobanura "kutanywa" mu kigereki cya kera.Mu mivugo yo mu kinyejana cya 5 cy'Ubufaransa, Bakusi, imana ya divayi, yasutse kristu hamwe na vino, ibyara gusa ibara ry'umuyugubwe.Amethyst, izwi kandi ku izina rya Amethystos, ikomoka ku bisobanuro "kudasinda".Bavuga ko kristu yuhira vino na Bakusi yabanje gukorwa numukobwa.Imiryango imwe yumwami wiburayi yemera ko Amethyst irimo imbaraga zidasanzwe zo gufasha uwambaye kubona umwanya nimbaraga.
Obsidian: Ni amabuye y'agaciro asanzwe, azwi kandi nka "dragon kristal" na "shisheng ibuye".Ni dioxyde de silicon isanzwe, mubisanzwe umukara.Obsidian imaze imyaka igera ku icumi ivugwa kandi nta murage w'amateka ufite.
Ijisho ry'ingwe: Ijisho ry'ingwe, rizwi kandi nk'ibuye ry'amaso y'ingwe, ni ubwoko bw'amabuye y'agaciro afite ijisho ry'injangwe, cyane cyane umuhondo w'umuhondo, ufite ubudodo nk'imirongo yoroheje imbere y'agaciro.Amabuye y'amaso y'ingwe ni bumwe mu bwoko bwa quartz.Ubu bwoko bw'amabuye y'agaciro bushobora gukorwa muri crocidolite fibre silicon yo gusimbuza pseudocrystal.
Pyrite: Pyrite (FeS2) ikunze kwibeshya kuri zahabu kubera ibara ryayo ry'umuringa ryoroheje kandi ryaka cyane, bityo ryitwa kandi "injiji zahabu".Ibigize mubisanzwe birimo cobalt, nikel na selenium, hamwe na NaCl ubwoko bwa kristu.Abafite ibice bimwe ariko biri muri sisitemu ya kristu ya orthogonal (orthorhombic) yitwa ubutare bwera.Hariho na cobalt, nikel, umuringa, zahabu, seleniyumu nibindi bintu mubigize.Iyo ibirimo ari byinshi, birashobora kugarurwa byimazeyo kandi bigakoreshwa mugikorwa cyo gukuramo sulfuru.
Umubiri wa gypsumu wuru ruganda rwo gucukura amabuye y'agaciro ni ibidukikije byangiza ibidukikije, bitazagira ingaruka mbi kubakoresha.
Ibikoresho bikoreshwa mu gucukura nabyo byatoranijwe neza.
Kubindi bisobanuro kubyerekeye ibicuruzwa, nyamuneka twandikire
