Kunyangwe fenicha yakagadzirwa neenamel yakangove yakakurumbira muChina mushure memakore ekuma1950, yakazove fenicha yemumba.
Zvisinei, kushandiswa kweamel sechinhu kune nhoroondo yakareba kwazvo, asi munguva dzekare yakanga isinganzi enamel, asi enamel.
Vanhu vekutanga kugona uye kushandisa enamel vaive vaIjipita vekare, uyezve maGiriki.Nhoroondo yekushandisa enamel munyika yangu zvakare yakareba kwazvo.Inogona kurondwa kumashure kwezana ramakore rechisere AD.Pakazosvika zana ramakore rechi 14, tekinoroji yeenamel yakave yakanyatso hunyanzvi.
Enamel chaizvoizvo yakabva kune girazi rekushongedza simbi.Icho chinhu chakaumbwa chinogadzirisa inorganic vitreous zvinhu pahwaro hwesimbi kuburikidza nepamusoro-tembiricha yekunyungudutsa tekinoroji, uye inogona kubatanidzwa zvakasimba nesimbi, senge chinhu chakaumbwa.Bhachi gobvu rakaita sependi rakaiswa pasimbi.
Muchidimbu, zvigadzirwa zveenamel zvinhu zvinonyanya kukamurwa kuita zvikamu zviviri: simbi zvinhu zveenamel uye enamel, inova inorganic vitreous material ine hushoma hutema pamusoro.
Nekudaro, munguva yakapfuura, nekuda kwekuganhurirwa kwehunyanzvi, tekinoroji yekukanda yaive zvakare kumashure zvakanyanya, saka enamel yaive yakadhura kwenguva yakareba munguva yakapfuura, saka kushandiswa kwaive kwakaganhurirwa zvakanyanya, uye zvishoma chete zvigadzirwa zvaive. inoshandiswa nevakuru.
Mushure mepakati pezana ramakore re19, nekuda kwekusimudzira shanduko yeindasitiri, tekinoroji yekukanda yakagadziridzwawo nekusvetuka-svetuka.Kubva panguva iyo, nyika dzakawanda dzakazarura nguva itsva yeamel yemazuva ano, uye zvigadzirwa zvakasiyana-siyana zveamel zvine zvinhu zvakasiyana-siyana zvakabuda imwe pashure peimwe.
