It often contains phenocrystals of the felsic mineral, which has a slightly lower crystallization temperature than the feldspar and quartz that form liolite.    Perfect for the Earth Science Classroom | Great for practicing identification and classification. The evolved chemistry of the rock makes it lighter compared to other igneous rocks - a suitable identifier for classification. A set of 6 samples perfect for group study or exams.    GEOLOGIST SELECTED | Each specimen is selected and hand-processed by a practicing geologist to ensure each sample exhibits its defining characteristics.    Locally Processed | Our rock and mineral samples are sourced from various locations around the world and processed in Victor, New York.    Individually Wrapped \u0026amp; Labeled | Each specimen sample is packaged in a clear bag with a label and barcode for easy identification. \u003cbr\u003e\u003cbr\u003e \n Raw rhyolite specimen set of 6 samples, 1 inch. Rhyolite is an aphanitic felsic rock that is formed during the eruption of thick, viscous magma. It often contains phenocrystals of the feldspar mineral, which have a slightly higher crystallization temperature than the feldspar and quartz that form lyolite. Great for teaching students about rounding and sorting, as well as practicing identification and sorting. The rock's evolved chemistry makes it lightweight compared to other igneous rocks - a good identifier for classification. Each specimen varies slightly in shape, size, and color, but is approximately 1 inch long. Each individually wrapped, labeled and barcoded for easy identification and storage. Selected and processed by geologists. Each specimen is selected by a real geologist and processed by hand to ensure that each sample exhibits distinct characteristics. Rocks and minerals are sourced from various locations around the world and hand processed in Victor, New York. Technical Support Feel free to contact our team of scientists and geologists anytime. We are happy to assist you with additional information or questions regarding rock and mineral samples. \u003cbr\u003e\u003cbr\u003e \u003cbr\u003eManufacturer: ‎Eisco\u003cbr\u003ePart number: ‎HESNG0049PK6\u003cbr\u003eItem weight: ‎200 g\u003cbr\u003eProduct size: ‎7.62 x 7.62 x 7.62 cm; 199.58 g\u003cbr\u003e Battery usage: No\u003cbr\u003eProduct dimensions (Length x Width x Height): 7.6 x 7.6 x 7.6 cm","brand":"Mega Shop Japan","offers":[{"title":"Default","offer_id":48992559956288,"sku":"B083TF2BQW","price":106.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/2584\/0704\/files\/71m4bzw31zL._AC_US1200.jpg?v=1718224335","url":"https:\/\/megashopjapan.com\/products\/6-pack-raw-liquid-crystal-rock-specimens-approximately-1-inch-selected-by-geologists-hand-processed-perfect-for-science-classrooms-class-pack-eisco-labs","provider":"Mega Shop Japan","version":"1.0","type":"link"}
