Iceland spar (calcite, mineral, ... Materials (hierarchy name)) |
|
Note: Transparent, naturally-occurring calcite crystal used in demonstrating the polarization of light. An oblong stone made of Iceland spar found in the wreck of a 16th-century English warship in 2013 has led archaeologists to speculate that the crystal is one and the same as the sunstone, a near-mythical navigational aid said to have been used by Viking mariners. |

Dutch ..... Transparant, in de natuur voorkomend calcietkristal dat wordt gebruikt om de polarisatie van licht te demonstreren. Na de vondst van een langwerpige steen van IJslandspaat in het wrak van een 16e-eeuws Engels oorlogsschip in 2013 speculeren archeologen dat het kristal hetzelfde is als zonnesteen, een welhaast mythisch navigatiemiddel dat door zeevarende Vikingen heet te zijn gebruikt. |
