The unglazed ceramic streak plate, made from high-quality porcelain, is an essential tool for performing the streak test in mineral identification\u2014a simple and effective method to determine a mineral’s identity based on the color of its powdered residue. By rubbing a mineral sample against the plate’s surface, a trace of powder is left behind. This residue reveals the so-called streak color, which may match or differ from the mineral\u2019s external color. Available in both white and black versions, the plate allows testing of minerals with varying tones, enhancing visual contrast for more accurate identification.<\/p>\n
HOW DOES THE STREAK TEST WORK?<\/strong> The unglazed ceramic streak plate is a compact and durable tool used to identify minerals by revealing their true streak color. Available in white and black, it enhances contrast for accurate observation during field or lab testing.<\/p>\n","protected":false},"featured_media":3012,"comment_status":"open","ping_status":"closed","template":"","meta":{"inline_featured_image":false,"_joinchat":[]},"product_brand":[],"product_cat":[1369],"product_tag":[928,927,925,924,926],"class_list":{"0":"post-4004","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-hardness-testing","7":"product_tag-1-x-1","8":"product_tag-2-x-2","9":"product_tag-ceramic","10":"product_tag-ceramic-streak-plates","11":"product_tag-streak-plates","13":"first","14":"instock","15":"shipping-taxable","16":"purchasable","17":"product-type-variable","18":"has-default-attributes"},"_links":{"self":[{"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/product\/4004","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/comments?post=4004"}],"version-history":[{"count":3,"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/product\/4004\/revisions"}],"predecessor-version":[{"id":4008,"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/product\/4004\/revisions\/4008"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/media\/3012"}],"wp:attachment":[{"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/media?parent=4004"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/product_brand?post=4004"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/product_cat?post=4004"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.minexproducts.com\/en\/wp-json\/wp\/v2\/product_tag?post=4004"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
