<h1>Obsidian Salju — Langit Mangsa Adhem Beku ing Kaca</h1>
<p class="lede"><strong>Obsidian salju</strong> iku kaca vulkanik ireng tengah wengi sing disebarake karo “salju” alus lan kaya bulu. Salju-salju kuwi dudu cat: kuwi <em>sferulit</em>—tuwuhan cilik radial saka mineral <strong>cristobalite</strong> sing mekar ing kaca nalika alon-alon dadi kristal. Asilé kaya salju sing mandheg ing udhara lan tetep ana ing watu selawase. Apik kanggo dideleng, nyenengake kanggo dipelajari.</p>

<h2>Identitas &amp; Jeneng 🔎</h2>
<div class="grid-2">
<div class="card">
<h3>Kaca vulkanik karo kembang mangsa rendheng</h3>
<p><strong>Obsidian</strong> kawangun nalika lava sing sugih silika adhem kanthi cepet banget nganti kristal ora duwe wektu kanggo tuwuh—asilé: kaca. Ing sawetara aliran, panas lan cairan sing isih ana banjur nyurung <strong>cristobalite</strong> kanggo kristalisasi ing <em>patches radial, kaya salju</em>. Mula saka jenengé.</p>
</div>
<div class="card">
<h3>Devitrifikasi ing aksi</h3>
<p>“Serpihan” kuwi yaiku watu sing alon-alon <strong>devitrifikasi</strong>—pindhah saka kaca menyang polimorf kuarsa mikrokristalin. Iki cara geologi nggawe gambar ing pinggir.</p>
</div>
</div>
<div class="note" style="margin-top: .6rem;">
<strong>Selingan nyenengake:</strong> Ing cahya mburi sing kuwat, kaca ireng kadhang nuduhake pinggiran coklat kola—tandha obsidian klasik.</div>

<h2>Kepiye “Salju” Mbentuk 🧭</h2>
<div class="grid-3">
<div class="card">
<h3>Nukleasi sferulit</h3>
<p>Titik wiji cilik ing kaca wiwit kristal minangka <strong>kristobalit</strong>. Jarum-jarum nyebar metu, nggawe tambalan bunder utawa wujud lintang sing mencerahake ireng.</p>
</div>
<div class="card">
<h3>Tuwuh &amp; jarak</h3>
<p>Ukuran lan kerapatan serpihan nggambarake sejarah adhem: kahanan alon lan rata nggawe “salju” luwih gedhé lan jarang; owah-owahan luwih cepet nggawe salju alus lan padhet.</p>
</div>
<div class="card">
<h3>Memori aliran</h3>
<p>Sawetara potongan njaga <strong>pita aliran</strong> samar—pita abu-abu alus ing kaca ireng—kanthi salju sing ngadeg ing ndhuwur kaya kali mangsa.</p>
</div>
</div>
<blockquote>Resep: lava riolitik + adhem cepet → kaca; tambah wektu + anget → sferulit salju.</blockquote>

<h2>Kosakata Palet &amp; Pola 🎨</h2>

<h3>Palet</h3>

<li>

<span class="swatch" style="background: #e5e7eb;"></span> <strong>Abu-abu es nganti putih</strong> — serpihan “kristobalit.”</li>
<li>
<span class="swatch" style="background: #4b5563;"></span> <strong>Halo asap</strong> — pinggiran nyebar ing sekitar sferulit luwih gedhé.</li>
</ul>
<p>Poles dhuwur menehi <strong>kilap cermin</strong> sing nggawe serpihan katon kaya ngambang ing sangisore permukaan.</p>
</div>
<div class="card">
<h3>Tembung pola</h3>
<ul>
<li>
<strong>Sferulit</strong> — semprotan kristal bunder lan radial (sing diarani “salju”).</li>
<li>
<strong>Roset</strong> — kumpulan serpihan sing mbentuk kembang luwih gedhé.</li>
<li>
<strong>Pita aliran</strong> — pita alus ing kaca saka gerakan kental.</li>
<li>
<strong>Tandha hackle</strong> — garis cilik kaya wulu cedhak retakan alami.</li>
</ul>
<p class="tip" style="margin-top: .5rem;"><strong>Tip foto:</strong> Gunakna cahya kunci gedhé lan alus kanggo njaga ireng tetep sugih; tambahna cahya sisih cilik kanggo menehi saben serpihan halo alus tanpa silau.</p>

<h3>Carane wong nggunakake</h3>
<p>Cabochon <strong>poles</strong>, <strong>manik-manik</strong>, <strong>ukiran</strong>, lan watu palem alus. Sajarah, pinggiran <strong>tajam banget</strong> saka obsidian nggawe dadi pilihan kanggo pedhang lan pucuk (saiki, luwih kanggo tampilan lan perhiasan).</p>

<h3>Pandhuan perhiasan</h3>
<ul>
<li>Apik kanggo <strong>liontin, anting, manik-manik</strong>; cincin luwih becik nganggo setelan pelindung.</li>
<li>Simpen kapisah—kuarsa lan korundum bisa nggores.</li>
<li>Poles dhuwur nuduhake bekas driji; refresh microfiber cepet mbalekake cermin.</li>
</ul>
</div>
<div class="card">
<h3>Ing roda</h3>
<ul>
<li>Tekanan entheng; obsidian bisa “orange-peel” yen kena panas.</li>
<li>Poles sadurunge nganti 3k–8k berlian; rampung nganggo <strong>serium oksida</strong> ing kain wol/kulit kanggo gloss ireng piano.</li>

<h2>Pitakonan ❓</h2>
<p><strong>Apa serpihan salju dicet utawa diwarnai?</strong><br>Ora. Iki <strong>sferulit kristobalit alami</strong> sing mbentuk ing njero kaca.</p>
<p><strong>Apa pola bakal owah wektu?</strong><br>Iki stabil ing kahanan kamar. Devitrifikasi sing nggawe serpihan wis kedadeyan ing jaman geologi kepungkur.</p>
<p><strong>Apa obsidian salju iku magnetik?</strong><br>Ora—bisa ana jejak wesi, nanging biasane <strong>ora magnetik</strong>.</p>
<p><strong>Apa gampang kethok gores?</strong><br>Iki medium keras (Mohs ~5–5.5) nanging <strong>rapuh</strong>. Aja kena benturan keras lan simpen adoh saka watu sing luwih keras.</p>
