These minerals are chemically and structurally similar to pyroxenes, but include water in their atomic structure. These properties make hornblende useful when studying both igneous and metamorphic rocks, as well as when learning the process behind mineral identification.\u003c\/div\u003e","brand":"Eisco Labs","offers":[{"title":"Default Title","offer_id":42993447567552,"sku":"ESNG0019HAND","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0250\/0623\/products\/ESNG0019_d2f9021d-f4ae-431c-8e99-c465195c8a37.jpg?v=1759453581","url":"https:\/\/www.thelabstockroom.com\/products\/esng0019hand","provider":"The Lab Stockroom","version":"1.0","type":"link"}
