Because most black inks are made up of more than one colour. When the ink gets wet, the colours separate.
The evidence that exists that marker ink is a mixture is that the ink can be separated into black and other color pigments. This can be done on filter paper by dotting the marker just above the edge and adding ethyl alcohol, which drags the pigments separately across the paper.
Yes black ink radiates more heat than white paper. This is because more heat is absorbed by black ink more than white paper and it is required to radiates more heat due to its heat capacity
Colors from black can be separated by a process called Chromatography.
The Chinese people found black rock and mixed it up with a lot of other stuff that made it All liquidy and thAts how ink was invented
Sand is not soluble in ink.
Dye and black ink can be separated by chromatography, where the mixture is dissolved in a solvent and allowed to move up a filter paper. The different components in the mixture will move at different rates based on their solubility in the solvent, allowing them to be separated visually.
its usually black but you might be able to get different ink colours
photo black ink is more expensive

One method to separate dyes of different colors in black ink is through a process called chromatography. In chromatography, the ink sample is placed on a material that allows the dyes to move at different rates, based on their chemical properties. As the dyes separate, they can be visually distinguished by the bands of different colors they produce on the material.
Black ink is a generic term used for many products from simple newspaper ink to highly sophisticated ink jet printer inks. Black ink is formulated primarily with carbon black pigment and a carrier vehicle in which it is finely dispersed. The vehicle can contain various oils and/or resins and additives, with or without solvents depending on application method, the substrate, and the drying conditions.
Yes, black printer ink is cheaper than colored ink in general. It's also easier to refill black ink yourself.
