What was the Icelandic spar used for?
Iceland spar is probably best known for exhibiting the optical property of double refraction – so, anything viewed through the crystal appears double. It has many uses, in everything from precision optical instruments to LCD screens, and was even used during WWII to make bombsights.

Spar is an old mining or mineralogy term used to refer to crystals that have readily discernible faces. A spar will easily break or cleave into rhomboidal, cubical, or laminated fragments with smooth shiny surfaces. Calcite often forms the dogtooth spar crystals found in vugs and caves.

Did Vikings use Iceland spar?
Vikings may have navigated by looking through a type of crystal called Icelandic spar, a new study suggests. In some Icelandic sagas—embellished stories of Viking life—sailors relied on so-called sunstones to locate the sun’s position and steer their ships on cloudy days.
Did Vikings use optical calcite?
Researchers say Vikings used transparent calcite crystal to fix the bearing of the Sun, to within a single degree of accuracy. Vikings, they argue, used transparent calcite crystal — also known as Iceland spar — to fix the true bearing of the Sun, to within a single degree of accuracy.

What is the hardness of Iceland spar?
3
Its hardness on the Moh’s scale is 3. Natural calcite crystals often look very different so it’s important to look at a variety of other images to get a feel for the look of this mineral. Many organisms create their shells out of the mineral calcite.
What is a Viking Sunstone?
The Norse sagas mention a mysterious “sunstone” used for navigation. Now a team of scientists claims that the sunstones could have been calcite crystals and that Vikings could have used them to get highly accurate compass readings even when the sun was hidden. Calcite is such a crystal.
