Mbiri ya kuyatsa nyali

Mikanda yagalasi yachikale, kupatula magalasi aku Asia ndi Africa, imachokera ku Venitian Renaissance ku Italy.Amakhulupirira kuti mikanda yakale kwambiri yagalasi yodziwika bwino idayamba m'zaka za zana lachisanu BC.Kuyang'anira nyali kudayamba kugwiritsidwa ntchito ku Murano, Italy m'zaka za zana la 14.Murano anali likulu la mikanda ya galasi padziko lapansi kwa zaka zopitilira 400.Opanga mikanda yachikhalidwe amagwiritsa ntchito nyali yamafuta kutenthetsa galasi lawo, komwe njirayo imatchedwa dzina lake.

Nyali zachikale zamafuta ku Venice zinali mosungiramo madzi okhala ndi chingwe komanso chubu chaching'ono chopangidwa kuchokera ku nsalu ya labala kapena phula.Mavuvu pansi pa benchi yogwirira ntchito ankawongoleredwa ndi mapazi awo pamene akugwira ntchito, kupopera mpweya mu nyali yamafuta.Mpweyawo unachititsa kuti nthunzi zamafuta ziwotche bwino kwambiri ndipo zimawongolera malawiwo.

Pafupifupi zaka makumi atatu zapitazo, akatswiri a ku America anayamba kufufuza njira zamakono zowunikira magalasi.Gululi pamapeto pake linapanga maziko a International Society of Glass Beadmakers, bungwe lodzipereka kuteteza njira zachikhalidwe ndi kupititsa patsogolo maphunziro.

Njira zopangira nyali

Pali njira zambiri zomwe mungagwiritse ntchito pa nyali mukayamba kuyatsa.Apa, tikambirana chilichonse kuyambira pa zinthu zofunika kwambiri monga kuyatsa nyali, mpaka luso lodzikongoletsa monga kudabwa.
