Dhayi chinhu chine ruvara chine affinity kune substrate kwachiri kuiswa.Iyo dhayi inowanzoiswa mune aqueous solution, uye inoda mordant kuti ivandudze kukurumidza kwedhayi pane fiber.

Zvose madhayi nepigment zvinoita kunge zvine ruvara nekuti zvinotora mamwe mafungu echiedza kupfuura mamwe.Kusiyana nedhayi, kazhinji pigment haina kunyungudika, uye haina hukama kune substrate.Mamwe madhayi anogona kudhayiwa nemunyu unert kuti abudise pigment yedhamu, uye zvichibva pamunyu wakashandiswa anogona kunge ari aluminium lake, calcium lake kana barium lake pigments.

Dhayi shinda dzeflakisi dzakawanikwa muRepublic of Georgia dzakanyorwa mubako rekare ku36,000 BP.Uchapupu hwezvinocherwa mumatongo hunoratidza izvozvo kudhaya kwave kuchiitwa zvakanyanya kwemakore anopfuura 5000, kunyanya muIndia neFenikiya.Iwo madhayi akatorwa kubva kumhuka, muriwo kana mineral kwakabva, pasina kana kushoma kwazvo kugadzirisa.So kure zvikuru kwakabva dhayi kwave kubva muchirimwas, kunyanya midzi, michero, bark, mashizha nehuni.
