O le ulo u'amea u'amea e faia i le u'amea lafo.A maeʻa ona faʻafefeteina, e sasaa i totonu o le limu ma faʻapipiʻi.A maeʻa ona faʻaogaina ma olo, e avea ma avanoa.A maeʻa ona faʻamalo, e mafai ona faʻafefe le faʻapipiʻi enamel.A maeʻa le faʻapipiʻiina, e tuʻuina atu i le ogaumu tao.Afai o se faailoga leisa, o le faʻapipiʻiina o le enamel e faʻaogaina.Fa'ailoga leisa pe a mae'a.
Tu'u u'amea enamel ipu enamel coating o se vaega o mea vitreous inorganic pipii i le pito i lalo o le ulo uʻamea, ona condensed i luga o le faavae uʻamea e ala i le liusuavai ma mausali tuʻufaʻatasia ma le uamea, ina ia fausia ai se enamel layer i luga o le mata o le. ulo.E sailia mo lona matagofie, mama, ma le vevela.I le taimi lava e tasi, ona o le mautu o vailaʻau o le ulo enamel, e mafai ona teuina meaʻai suamalie ma alkaline.
O ipu enamel o loʻo iai e masani ona paʻepaʻe, ma o mea faʻafefete faʻaaogaina mo enamel paʻepaʻe o le silicon oxide, alumini oxide, manganese oxide, potassium oxide ma sodium oxide, ma e leai se taʻitaʻi, o lea e leai se lamatiaga o le alumini oona.Ae ui i lea, talu ai o le enamel layer o le enamel ipu e matua faigofie lava ona faʻaleagaina pe a paʻu, e tatau ona matua faʻaeteete i le taimi o le faʻaaogaina e puipuia ai le faaleagaina o le enamel layer.
