which pigment do we now call kohl- a copper ore or galena, a gray-black eye paint
Out of the choices of malachite, copper, or gray-black, the pigment you would now call kohl is gray-black. Kohl was a form of eye paint used like eyeliner or eye shadow by the Egyptians.
Kohl is a black pigment traditionally made from galena, which is a gray-black mineral. Malachite is a green mineral that is sometimes used as a source of the green pigment in eye paints or cosmetics. Copper ore is not typically used as an eye paint pigment.
Kohl was a pigment used for eye makeup in Ancient Egypt. It consisted mainly of galena, which is a type of lead, as well as malachite and cerussite.
i am not for sure but it one of these malachite a copper ore or galena,gray-black eye paints
Real old-fashioned kohl like the ancient Egyptians wore is ground-up lead ore. A similar product called kajal is made by dipping cloth in sandalwood paste repeatedly, letting it dry then burning it and collecting the soot.
pigment used to make pain is NOT SAFE for the eye area! they are two different things, because pigments meant for the eye have been tested as safe for that area.
So we don't see in black and white cuhh
yes (True) Although irises come in different colors (iris = rainbow), they contain only brown pigment. When they have a lot of pigment, the eyes appear brown or black. If the amount of pigment is small and restricted to the posterior surface of the iris, the unpigmented parts simply scatter the shorter wavelengths of light and the eyes appear blue, green, or gray. Most newborn babies' eyes are slate gray or blue because their iris pigment is not yet developed.
no. it is probably toxic. try some liquid eye liner that is black. it's like paint, but safe
The choroid layer in the eye has a black color pigment on it. Also, the light entering the eye is not reflected because light rays entering the pupil are absorbed by the tissues inside the eye.
Because black pigment does not reflect any part of the colour spectrum back to the eye.
Yes, the pupil can take on a lighter shade of gray, even to the point of appearing shiny and silvery. Red eye is caused by light shining back from the retina in the eye, so with black & white, a lighter shade of gray is the result.
