If one of the intervening states was a superpower, a civil war is a further 72% longer; a conflict such as the Angolan Civil War, in which there is two-sided foreign intervention, including by a superpower (actually, two superpowers in the case of Angola), would be 538% longer on average than a civil war without any international intervention.
Shellac is a wood finishing product made by dissolving dried resin in denatured alcohol. Shellac was used heavily for finishing furniture during the 19th and early 20th centuries, and it is still available for use today. The product is popular due to its ease of application, low odor, and all-natural origin.
Shellac is a blend of gel and nail polish. Because it is like a polish, it canât be used to extend your nail. Because it is like a gel, however, it does add strength and durability. In the long term Shellac is much less damaging to nails than traditional Gels (or Acrylics). The main benefit is that it reduces chipping.
