When was chromatography first discovered?
The name Chromatography is coming from the Greek "Chromos" ("colour") and "grafein" (" to write") so chromatography is "writing with colours". This refers to the first chromatographic experiments with plant pigments were the sample was put on a filter paper, dried and the separation obtained by dropping "eluans" on it so that concentric (at that time only coloured) rings were formed
Are pigments man-made?
Some pigments are man-made, or synthesized. These include white lead, blue frit, Alizerian crimson, and Prussian blue. the ability to synthesize pigments lowered the cost of acquiring colors for oil painting.
What are 2 synthetic materials?
Generally speaking synthetic materials are man made and do not occur in nature. Example are plastics certain alloys etc. There are some things that can be both synthetic and natural such as some drugs and chemicals
What are cartonoid pigments?
Carotenoid pigments are a group of naturally occurring pigments found in plants, algae, and some bacteria. They are responsible for the yellow, orange, and red colors in fruits and vegetables. Carotenoids have antioxidant properties and play a role in plant photosynthesis.
Do all plants have green pigments?
No, not all plants have green pigments. While chlorophyll is the most common pigment that gives plants their green color, some plants may have other pigments like red, yellow, or purple. These pigments can help the plants absorb different wavelengths of light for photosynthesis.
What is paint for houses made out of?
House paints are typically made of pigments, binder, and solvent. Pigments contain the colors, the binder holds everything together, and the solvent to provide consistency when you paint. Some paints are made from latex or acrylic, some are oil based, and some have other synthetic substance like elastomer.
When was first cancer discovered?

Is there a red paint or red nail polish or red ink or any red pigment that will NOT fluoresce?
There are red pigments that do not fluoresce under UV light, such as natural iron oxides or cadmium red. However, some red pigments, especially organic ones like certain dyes or some synthetic red pigments, may exhibit fluorescence. It is best to test the specific product in question to determine if it fluoresces or not.

What did neolithic man discover when the heated some rock?
Neolithic man discovered that heating some rocks could produce heat for cooking food, create tools by shaping and hardening the rocks, and create pigments for painting or body decoration.
Who created fluorescent?
Fluorescent materials occur naturally in some minerals, but the development of synthetic fluorescent materials is credited to George Stokes, a British physicist who discovered fluorescence in 1852. The earliest synthetic fluorescent dyes were created in the late 19th and early 20th centuries.
