Indigo paurableu paura whakaheke waikano

Whakaahuatanga Poto:

He momo waikano whakaheke paura bleu, a ko te hua tuatahi o te indigo. Ka mahia ma te tunu i te keke tātari mai i te waahanga o mua. Kare e rewa i roto i te wai, te waihano me te ethyl ether, engari ka whakarewahia te waikura benzoyl oxide. I whakamahia te nuinga ki te tae me te ta o te muka miro, a ko te tae motuhake mo te papanga jean. Ka taea hoki te tukatuka hei waikano kai me te kaihoko matū koiora.
