It's the darker gold, just before black, that he finds most beautiful: a low ember color, darker than a glowing coal.

The mental representation of the visual stimuli are referred to as icons (fleeting images.) Iconic memory was the first sensory store to be investigated with experiments dating back as far as 1740. One of the earliest investigations into this phenomenon was by Ján Andrej Segner, a German physicist and mathematician. In his experiment, Segner attached a glowing coal to a cart wheel and rotated the wheel at increasing speed until an unbroken circle of light was perceived by the observer. He calculated that the glowing coal needed to make a complete circle in under 100ms to achieve this effect, which he determined was the duration of this visual memory store.

An angithi (Hindustani: अंगीठी or انگیٹھی) is a traditional brazier used for space-heating and cooking in the northern areas of South Asia, mainly in India, Pakistan and Nepal. Angithis usually generate heat from burning coal and, when in use, have glowing coal or charcoal pieces but few or no flames.

Static discharge may also ignite acetone vapors, though acetone has a very high ignition initiation energy point and therefore accidental ignition is rare. Even pouring or spraying acetone over red-glowing coal will not ignite it, due to the high concentration of vapour and the cooling effect of evaporation of the liquid.Acetone MSDS.

The large demand for cyanides for mining operations in the 1890s was met by George Thomas Beilby, who patented a method to produce hydrogen cyanide by passing ammonia over glowing coal in 1892. This method was used until Hamilton Castner in 1894 developed a synthesis starting from coal, ammonia, and sodium yielding sodium cyanide, which reacts with acid to form gaseous HCN.

The fact that a glowing coal appears as a line of light when it is moved around quickly has often been used to illustrate the idea of persistence of vision. It is known as the "sparkler's trail effect", named after the trail that appears when a sparkler is moved around quickly. The effect has been applied in the arts by writing or drawing with a light source recorded by a camera with a long exposure time.

Carbuncle (In Spanish: Carbunclo, Carbunco or Carbúnculo) is a legendary species of small animal in South American folklore, specifically in the mining folklore of northern Chile. The animal is said to contain riches of some sort; in some versions it is a precious stone that gives fortune and good luck to its owner. The description of the animal vary. The chaplain and explorer Martín del Barco Centenera describes it in La Argentina (1602) as "a smallish animal, with a shining mirror on its head, like a glowing coal".

203] A Jewish man, Johannes Pfefferkorn, met a particularly gruesome death in 1514 in Halle. He had been charged with a number of crimes, such as having impersonated a priest for twenty years, performing host desecration, stealing Christian children to be tortured and killed by other Jews, poisoning 13 people and poisoning wells. He was lashed to a pillar in such a way that he could run about it. Then, a ring of glowing coal was made around him, a fiery ring that was gradually pushed ever closer to him, until he was roasted to death.

Ein Gesang auf Peter Nirsch On the second day, his feet were smeared with heated oil and then held above glowing coal, thereby roasting him. On the third day, 16 September 1581, he was dragged to the place of execution and broken on the wheel; the wheel was slammed down upon him 42 times.For purposes of comparison, a "typically" severe act of breaking alive may usually have limited itself to 8 or 9 acts of breaking; two on each arm, below and above the elbow joint, and two on each leg, above and below the knee. The ninth blow might be onto his spine, breaking it, or, out of mercy, it might be a final death blow directly on the chest, rupturing the heart or lungs, or onto the throat, effectively decapitating the individual.
