Where the ruby and obsidian versions announce themselves in solid colour, the stone sealed inside this shaft is rock crystal quartz — colourless, and close enough to the clarity of the surrounding borosilicate glass that at a glance the pen can look almost empty. Look closer and the fragments give themselves away by their edges: sharp, faceted breaks that catch and bend light differently than the smooth glass around them, and glint independently of whatever the storm glass liquid is doing that day.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eA Stone That Hides in Plain Sight\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eRock crystal is quartz in its purest, most transparent form — the same mineral that shows up coloured as amethyst or citrine, here with none of the trace elements that would tint it. That absence of colour is exactly the point: instead of competing with the storm glass crystals for attention, the quartz fragments blend into them, so that on a cold day it can take a moment to tell where the mineral ends and the temperature-formed crystal begins.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eThe Pen Itself\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eEvery Storm Glass+ pen is shaped freehand over an oxygen torch by Kiyoshi Matsumura at \u003ca class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"\/pages\/matsubokkuri-glass-pens\"\u003eGlass Studio Matsubokkuri\u003c\/a\u003e in Suginami, Tokyo.

Because both the quartz and the storm glass crystals are colourless, this is the one Storm Glass+ pen where lighting matters more than usual: held under a desk lamp or near a window, the facets throw off small flashes that are easy to miss in flat light. Rinse under lukewarm water after use and avoid sudden temperature swings, which can stress the glass shaft.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhy is the stone so hard to see?\u003c\/strong\u003e\u003cbr\u003eBecause rock crystal quartz is naturally colourless. Unlike the coloured stones in the Storm Glass+ line, it doesn't stand apart from the surrounding glass and liquid — it's meant to be discovered by its facets and glints rather than its colour.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWill the quartz look different from the one pictured?\u003c\/strong\u003e\u003cbr\u003eSlightly. Each fragment is broken from natural rock crystal, so the exact shape and the way it catches light will vary pen to pen, even though the colour stays consistently clear.\u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eBilingual service — English and French.\u003c\/strong\u003e\u003c\/h3\u003e","brand":"Shosai","offers":[{"title":"Fine","offer_id":48621874249953,"sku":"1418357","price":189.99,"currency_code":"CAD","in_stock":true},{"title":"Medium","offer_id":48621874282721,"sku":"1418358","price":189.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0806\/8032\/1249\/files\/1_0518af74-58d0-47e8-b882-991510022f91.png?v=1783196193","url":"https:\/\/shosai.ca\/products\/matsubokkuri-storm-glass-plus-crystal-glass-pen","provider":"Shosai","version":"1.0","type":"link"}
