As Vantablack is composed of carbon nanotubes that absorb exceptionally high levels of visible light, it is widely considered one of the darkest pigments created. When applied to three-dimensional objects, Vantablack produces the appearance of a two-dimensional surface or void space.
Lead pigments. Naples yellow (PY41). Lead-tin-yellow: PbSnO 4 or Pb(Sn,Si)O 3. Titanium pigments. Titanium yellow (PY53): NiO·Sb 2 O 3 ·20TiO 2; Tin pigments. Mosaic gold: stannic sulfide (SnS 2). Zinc pigments. Zinc yellow (PY36): zinc chromate (ZnCrO 4), a highly toxic substance with anti-corrosive properties which was historically most ...
Andy Kellman of AllMusic took note of "Like she took her father and Roberta Flack's "Be Real Black for Me" to heart and then some, Lalah Hathaway titled her eighth solo album after the darkest known pigment and poured the same warm and loving sentiments into the music. Purists who didn't appreciate the bold left turn the singer took with ...
This week, uncover a lost recipe for history’s most valuable pigment, explore an asteroid with a watery past, go inside Iceland’s volcanic eruptions, and more. Bronze Age workshop reveals ...
Iron oxide copper-gold deposits are also often associated with other valuable trace elements such as uranium, bismuth and rare-earth metals, although these accessories are typically subordinate to copper and gold in economic terms. Some examples include the Olympic Dam, South Australia, and Candelaria, Chile deposits.
Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero. The actual albedo varies depending on the source material and ...
Shakudō (赤銅) is a Japanese billon of gold and copper (typically 4–10% gold, 96–90% copper), one of the irogane class of colored metals, which can be treated to develop a black, or sometimes indigo, patina, resembling lacquer.
Several commercial optical black coating products such as Vantablack and adVANTA nanotube optical blacks [23] have been produced from VANTA coatings. VANTA absorbers may also increase the absorption of heat in materials used in concentrated solar power technology, as well as military applications such as thermal camouflage.
