Mtundu: CHIYE GLASS BEAD
Kupera magalasi okhala ndi NO SILICA YAULERE, ndipo amapangidwa kuchokera ku galasi labwino kwambiri la soda. Magalasi amtunduwu amasinthidwa ndiukadaulo wozungulira wa uvuni ndipo umakhala ndi njira yapaderadera yozungulira, kutsuka, kupukuta ndi kuzing'amba, ndipo kumapangitsa magalasi olimba kwambiri.Popanda kugwiritsa ntchito hydro-fluoric acid, akupera magalasi amitundu sikungokhala osasamala zachilengedwe, ndi zonyezimira komanso zosadetsedwa. Njira yapaderayi imapangitsa magalasi opera opanda zodetsa, kuyeretsa komanso kutsuka mosavuta ndipo mkanda uliwonse woyang'anira umatenga gawo lofunikira pakupera ndipo walowa m'malo azofalitsa wamba: Mchenga wa Ottawa, Mipira yachitsulo, Miyala, Mipira ya Ceramic etc. mphero, Mphero mphero, Kukopa mphero. Amakhala okhazikika pamankhwala ndipo sadzachitapo kanthu kapena kuyankhidwa ndi zinthu zomwe zili pansi. Amakhala ndi magalasi osalala bwino motero amatumphuka popanda kukangana pamenepo pochepetsa katundu pamakina oyambitsa. Mphamvu yokoka kukhala 1/3 ya kuwombera kwazitsulo. Potero gawo limodzi ndi kulemera lidzaphimba voliyumu yomweyo poyerekeza ndi magawo atatu polemera kwa Zitsulo kuwombera, potero kumachepetsa katundu pamphero. Izi sizimangochepetsa kugwiritsidwa ntchito kwamagetsi chifukwa chotsika katundu, ndiyotsikiranso mtengo poyerekeza ndi atolankhani ambiri opera.

Chiphaso
Kupera magalasi opangidwa ndi magalasi apamwamba amakhala ndi mphamvu zamagetsi, s2 ndi 2 kuposa 70%, kuuma kumatha kufikira 6-7 Mohs, ndipo imakhala yolimba yokwanira, yosavuta kuthyoka, itha kugwiritsidwa ntchito kangapo. Unifomu Wabwino, kuchuluka kozungulira ndikokulirapo kuposa kapena kofanana ndi 80%, ndipo kukula kwa tinthu ndi yunifolomu. Pambuyo kupopera mbewu, kuwala koyefishienti kwa chipangizocho kumasungidwa yunifolomu, ndipo kumakhala kovuta kusiya watermark. Zosasunthika, zopangidwa ndi magalasi osakanikirana ndi soda, okhala ndi magalasi abwino, poyerekeza ndi zinthu zina zopera, kupera mikanda yamagalasi sikuipitsa chitsulo chosinthidwa, kumatha kupititsa patsogolo kuyeretsa, ndikukhalabe ndi kulondola kwa chinthu choyambirira. Smooth komanso zosadetsedwa, chifukwa cha mawonekedwe amitundu yaying'ono, osadetsedwa; yosalala, ndi kumaliza bwino, kufikira miyezo yapadziko lonse ndi yapabanja. Mipira yamagalasi ya Olan yakhala ikupitilira kugaya mikanda yamagalasi, mwina ngati yotsika mtengo kapena ntchito yayikulu yina kuposa mikanda ya ceramic. Magalasi a Olan amagwiritsidwanso ntchito popera zinthu zopusa zomwe mikanda ya ceramic silingagwiritsidwe ntchito pazifukwa zosiyanasiyana. Kudziwitsa kwathu kwakukulu pakupera ukadaulo kumatithandiza kuti tikwaniritse magalasi athu ogwiritsira ntchito ngati mikanda yopera. Kuphatikiza apo, timagwiritsa ntchito mphero zopera mikanda pakupanga kwathu ndi malo athu aluso ndipo potero titha kupatsa makasitomala athu upangiri wowonjezera ndikuwongolera njira zawo zopangira ndi njira zoyenera.
