Cracks and fissures (17/09/22 10:12:16)
    We see these days that conflicts between former soviet republics are manifesting themselves as armed skirmishes. Russian troops have been present as a stabiliser. Now those soldiers are instead being sent to become torturists in Ukraine - and then cannon fodder.

    Nothing (AFAIK) has so far happened between ethnic groups in the russian federation. There is plenty of potential.

    But suppression for decades, even centuries, by murdering the opposition, plus merciless lies and propaganda, and a deliberately poor education system, most likely has had the effect of eradicating opposition from both the mental pool and the genetic pool of the peoples involved. Interesting, though, it will be when surviving soldiers from the Ukrainian war of aggression come home and tell their stories.

    Cracks and fissures?


    "A crack is a broken piece of countertop that is most of the time, chipped, uneven, and widely separated and is usually the result of man-made stresses. On the other hand, a fissure is a part of the stone that resembles a crack, yet it is a result of natural geological formation or mineral crystallization. However, sometimes a fissure may develop into a crack. In some cases, a fissure can affect the soundness of the stone although it’s rare.

    To spot a crack from a fissure there are a few different tests you can perform yourself to help spot the difference. One way to help distinguish between the two is by running your fingernail across your countertop. When running your fingernail across a fissure your nail should glide over it smoothly as a fissure doesn’t change the surface of your stone top. When running your fingernail over a crack, your nail will not glide smoothly as there will be a noticeable unevenness. Another way to tell if you have a crack or fissure is by looking at the stone from a low angle, a crack will have two points of reflection whereas a fissure will have one.

    Fissures are naturally occurring in stone and help to add character to your countertop, considering this, nothing should be done about them. If you notice a crack in your countertops, you should get in contact with a trained professional to restore it properly."
