Obsidian<\/a> ist ein nat\u00fcrliches vulkanisches Glas, das beim schnellen Abk\u00fchlen von kiesels\u00e4urereichem Magma entsteht. Das Mineral hat in der Regel eine tiefschwarze Farbe und einen glasartigen Glanz, kann aber auch Varianten mit Einschl\u00fcssen oder Farbspritzern aufweisen, wie Schneeflockenobsidian oder Regenbogenobsidian. Seine Struktur ist amorph, d. h. er hat kein Kristallgitter.<\/p>\n Obsidian ist weltweit in vulkanischen Gebieten zu finden, unter anderem in Island, Mexiko, den Vereinigten Staaten und Japan. Da er keine kristalline Struktur hat, wird er technisch nicht als Mineral, sondern als Gestein vulkanischen Ursprungs eingestuft. Seine Zusammensetzung besteht haupts\u00e4chlich aus Siliziumdioxid (SiO\u2082), und seine H\u00e4rte liegt zwischen 5 und 5,5 auf der Mohs-Skala.<\/p>\n Quellen: <\/strong> Selenit<\/a> ist eine klare bis durchscheinende Variante des Minerals Gips (CaSO\u2084-2H\u2082O). Er ist bekannt f\u00fcr seinen glasigen bis perligen Glanz und seine oft faserige Struktur. Eine h\u00e4ufige Form ist der Selenit, der einen Seidenglanz hat und in langen, faserigen Kristallen vorkommt. Trotz seines Namens hat Selenit nichts mit dem Element Selen zu tun; der Name leitet sich vom griechischen Wort f\u00fcr Mond ab, wegen seines weichen Glanzes.<\/p>\n Selenit bildet sich in sediment\u00e4ren Umgebungen w\u00e4hrend der Verdunstung von Meerwasser und ist in L\u00e4ndern wie Mexiko, Marokko, den USA und Australien zu finden. Es ist ein weiches Mineral mit einer H\u00e4rte von 2 auf der Mohs-Skala, so dass es sich leicht von Hand bearbeiten l\u00e4sst. Fast der gesamte auf dem niederl\u00e4ndischen Markt verkaufte Selenit ist Satinspat; Selenit ist jedoch ein vom Markt akzeptierter Handelsname.<\/p>\n Quellen: <\/strong> Eis-Obsidian-Gl\u00fccksflasche aus China<\/p>","protected":false},"featured_media":53923,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"soort":[],"product_brand":[],"product_cat":[3250],"product_tag":[],"class_list":{"0":"post-54044","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-geluksflesjes","7":"pa_herkomst-china","8":"pa_soort-ijs-obsidiaan","9":"pa_soort-obsidiaan","10":"pa_verkoopeenheid-per-10-stuks","11":"pa_vorm-geluksflesje","12":"pa_vorm-split","13":"desktop-align-center","14":"tablet-align-center","15":"mobile-align-center","16":"ast-product-gallery-layout-horizontal-slider","17":"ast-product-gallery-with-no-image","18":"ast-product-tabs-layout-horizontal","20":"first","21":"instock","22":"taxable","23":"shipping-taxable","24":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/54044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media\/53923"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=54044"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=54044"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=54044"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=54044"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=54044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
