Organic inclusions in amber

04 April 2020

Inclusions, in other words, are pieces of bark, leaves or forest floor, but also tiny animals like insects or spiders, which fell into the trap of tree resin and remained there forever. The mentioned inclusions are called organic. There are also inorganic, which include: sand, dust or small air bubbles.

Small pieces of amber in the form of icicles are those in which you can find the most remnants of very old plants and animals. The form of their creation is of great importance. More precisely, the resin dripped on the outside of the tree trunk and thus congealed, forming the shape of an icicle. Another form is the so-called plywood, which was created as a result of the accumulation of successive layers of resin, on which insects or other inclusions used to sit, and then they became covered with another layer. As a result, not only one insect can be found in the resin, but a much higher volume of inclusions.

 The smaller the animal fell into the congealing resin, the greater the likelihood was of keeping the trapped insect in a good condition.

 It cannot be concealed that amber containing inclusions is much more interesting and states as an object of desire for researchers. The fact that insects were there, determines their eternity. The process can be compared to the metaphor of time that has stopped for them when they embedded in hot resin. Thanks to this, the inclusions can be watched and admired by many people today. It is a symbol of something that has survived for many thousands of years.
