Description
  • Zčernání povrchu jeskyní je způsobeno: 1- kouřovými částicemi, Mn-povlaky a degradovanými povlaky sinic.
  • The origin of black surfaces generaly attributed to soot particles in caves is often a matter of dispute. There are three basic mechanisms of black surface formation: 1. open fires which create soot particles that slowly (sometimes within 2 dayes) sediment down. 2. organic coatings. 3. Mn-coatings are common but they are usually associated with rusty Fe-coatings. The experiments with open fires in caves revealed one important phenomenon - even small, ordinary fire will fill very large spaces with smoke that may slowly settle down during next one two days. One should abandon the idea of prehistoric men sitting in the interior of cave around a fire, instead we should look out for other technological means such as use of charcoal or non-smoking materials.
