Amacupa yikirahure ni ibikoresho gakondo byinganda mubushinwa. Mu bihe bya kera, abantu batangiye kubibyaza umusaruro, ariko biroroshye. Kubwibyo, bike byuzuye ibirahuri birashobora kuboneka mubisekuruza bizaza.
Ibikorwa byayo byo gukora ntabwo bigoye. Ba injeniyeri bakeneye kumenagura ibikoresho bibisi nkumusenyi wa quartz n ivu rya soda, bakabishiraho nyuma yubushyuhe bwo hejuru, kugirango berekane neza.
No muri iki gihe, amacupa yikirahure aracyafite umwanya wingenzi mugihe ibikoresho bitandukanye bipfunyika byinjiye kumasoko, birahagije kwerekana uburyo abantu bakunda icupa ryapakira.
Inkomoko y'ibirahure
Ibirahuri bimaze kumenyekana cyane mubuzima bwa kijyambere, uhereye kumadirishya yo hanze yinyubako ndende kugeza kuri marble yakinwe nabana. Waba uzi igihe ikirahuri cyakoreshejwe bwa mbere mubicuruzwa byo murugo? Abashakashatsi bavumbuye binyuze mu bucukumbuzi bw'ibyataburuwe mu matongo ko amasaro y'ibirahure yacukuwe mu matongo ya kera ya Misiri nko mu myaka 4000 ishize.
Ndetse nyuma yimyaka 4000, hejuru yaya masaro mato yikirahure aracyafite isuku nkibishya. Igihe nticyigeze kibasigaho. Byinshi, hariho umukungugu wamateka. Ibi birahagije kwerekana ko ibicuruzwa byibirahure bigoye cyane kubora muri kamere. Niba nta kwivanga mubintu byamahanga, birashobora kubikwa byoroshye muri kamere mumyaka 4000, cyangwa birebire.
Iyo abantu ba kera bakoze ibirahure, ntibari bazi ko bifite agaciro gakomeye ko kubungabunga; Mubyukuri, bakoze ikirahuri mu mpanuka. Mu mico ya kera y'Abanyamisiri hashize imyaka 4000, igihe ubucuruzi hagati y’ibihugu by’umujyi bwari bugenda butera imbere, hari ubwato bw’abacuruzi bwari bwuzuye amabuye ya kirisiti bita "soda naturel" yatembaga mu nyanja ya Mediterane.
Icyakora, umuraba waguye vuba cyane ku buryo ubwato bw'abacuruzi butabonye umwanya wo guhunga bwerekeza mu nyanja y'inyanja maze buhagarara hafi y'inyanja. Biragoye cyane ko ubwato bunini bugenda butwarwa nabakozi. Turashobora kuva mubibazo gusa kwibiza ubwato mumazi kumuraba mwinshi bukeye. Muri icyo gihe, abakozi bamanuye inkono nini mu bwato kugira ngo bacane umuriro bateke. Abantu bamwe bavanye amabuye mu bicuruzwa barayubaka mu kigo cy’umuriro.
Igihe abakozi babaga bafite ibyo kurya no kunywa bihagije, bateganya gukuramo inkono basubira mu bwato kuryama. Muri iki gihe, batunguwe no kubona ko ubutare bwakoreshwaga mu gutwika umuriro bwarasobanutse neza kandi busa neza cyane nyuma y’izuba rirenze. Nyuma, twamenye ko byatewe nubushakashatsi bwakozwe hagati ya soda karemano n'umusenyi wa quartz kumusenyi munsi yumuriro. Ngiyo isoko yambere yikirahure mumateka yabantu.
Kuva icyo gihe, abantu bamenye uburyo bwo gukora ibirahure. Umusenyi wa Quartz, borax, hekeste hamwe nibikoresho bimwe bifasha birashobora gushongeshwa mumuriro kugirango bitange ibirahuri bibonerana. Mu myaka ibihumbi yakurikiyeho yubusabane, imiterere yikirahure ntabwo yigeze ihinduka.
