Taupānga

1.Ko te hanga karaihe ko tetahi o nga tino whakamahinga o te konutai warowaiha.Ka honoa ki te silica (SiO2) me te konupūmā warowaihā (CaCO3) ka whakawerahia ki te tino mahana, ka tere rawa te whakamatao, ka puta te karaihe.Ko tenei momo karaihe e mohiotia ana ko te karaihe houra kotakota.

2. Ka whakamahia hoki te pungarehu houra hei horoi i te hau me te whakangawari i te wai.

3. Hangaia te houra me te waikano

4. metallurgy (tukatuka rino me te tangohanga rino aha atu),

5. (karaihe papatahi, oko parukore)

6. te whakamarumaru o te motu (te hanga TNT, te 60% gelatin-type dynamite) me etahi atu waahanga, penei i te hinu toka, te hanga pepa, te peita, te para tote, te whakamarumaru o te wai pakeke, te hopi, te rongoa, te kai me etahi atu.
