Black soot absorbs thermal radiation very well; it has an emissivity as large as 0.97, and hence soot is a fair approximation to an ideal black body. [21] [22] With the exception of bare, polished metals, the appearance of a surface to the eye is not a good guide to emissivities near room temperature.
Soot in very low concentrations is capable of darkening surfaces or making particle agglomerates, such as those from ventilation systems, appear black. Soot is the primary cause of "ghosting", the discoloration of walls and ceilings or walls and flooring where they meet.

The word aethalometer is derived from the Classical Greek verb aethaloun, meaning "to blacken with soot ...

This school standardized cooking practices and recipes, and laid the groundwork for the culinary arts schools that would follow. [14]
