Bandhiga Alaabta
Marka lagu daro kordhinta saliidda, daaweynta oksaydhka madow waxay sidoo kale abuurtaa jeebado yaryar oo dusha sare ah qalabka kuwaas oo awood u leh inay qaboojiyaan meel u dhow cidhifka goynta muddo dheer. Natiijadu waxay tahay daaweynta dusha sare ee oksaydhka madow ee birta xawaaraha sare leh, qalabku wuxuu kor u qaaday caabbinta kulaylka waxaana lagu kordhiyey nolosheeda qalabeed, oo leh lakab khafiif ah oo oksaydh ah oo ka duwan sida caadiga ah loo isticmaalo in lagu aqoonsado qalabka birta cobalt; waxqabadkeedu wuxuu la mid yahay qalabka aan dahaarka lahayn. Waxaa suurtagal ah in la isticmaalo suunka wareega oo leh noocyo badan oo kala duwan oo qalabaysan.
Qalabyada kala qaybsan ee 118 ama 135 digrii waxay ka dhigan tahay in xoog yar loo baahan yahay in lagu dhex qodo qaybta shaqada, taasoo ka hortagaysa in daloolku simbiriirixdo oogada maaddada, is-xakamaynta iyo yaraynta riixitaanka loo baahan yahay in la qodo. Layliskani waxa uu leeyahay nakhshad gaar ah oo leh caarad is-xakameyn ah oo ka hortagaysa sibbashada, shaqada ka dhigaysa mid dhakhso badan oo fudud. Kordhinta xawliga daloolku waxay ka dhigan tahay kulayl yar ayaa dhasha iyo daal badan ayaa la gaadhay, taas oo kordhinaysa nolosha layliga. Cidhifka goyntu waa mid fiiqan oo u adkaysata isticmaalka joogtada ah. Markaad ka shaqaynayso jihada ka soo horjeeda (goynta gacanta midig), gooyayaasha helical-falid leh waxay kor u saarayaan jajabyada kor u qaadista gooynta si ay u yareeyaan xirmidda.
