Howlite<\/a> ist ein Kalziumborsilikat, das in der Regel wei\u00df mit grauen bis schwarzen Adern ist, was ihm ein marmor\u00e4hnliches Aussehen verleiht. Aufgrund seiner por\u00f6sen Struktur wird Howlit oft eingef\u00e4rbt, um T\u00fcrkis zu \u00e4hneln. Das Mineral wurde 1868 in Nova Scotia, Kanada, entdeckt und ist nach dem kanadischen Chemiker Henry How benannt.<\/p>\n Howlit kommt haupts\u00e4chlich in Kanada, China und den Vereinigten Staaten, insbesondere in Kalifornien, vor. Er bildet sich in borreichen Evaporitumgebungen und ist oft in kleinen Ablagerungen in Sedimentgestein zu finden. Seine chemische Formel lautet Ca\u2082B\u2085SiO\u2089(OH)\u2085 und seine H\u00e4rte betr\u00e4gt 3,5 bis 6,5 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> Howlite-Gl\u00fccksflasche aus China<\/p>","protected":false},"featured_media":53904,"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-54025","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-geluksflesjes","7":"pa_herkomst-china","8":"pa_soort-howliet","9":"pa_verkoopeenheid-per-10-stuks","10":"pa_vorm-geluksflesje","11":"pa_vorm-split","12":"desktop-align-center","13":"tablet-align-center","14":"mobile-align-center","15":"ast-product-gallery-layout-horizontal-slider","16":"ast-product-gallery-with-no-image","17":"ast-product-tabs-layout-horizontal","19":"first","20":"instock","21":"taxable","22":"shipping-taxable","23":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product\/54025","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\/53904"}],"wp:attachment":[{"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/media?parent=54025"}],"wp:term":[{"taxonomy":"soort","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/soort?post=54025"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_brand?post=54025"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_cat?post=54025"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.ruschmineralen.nl\/de\/wp-json\/wp\/v2\/product_tag?post=54025"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
