{"product_id":"robax-ceramic-fireplace-glass-cut-to-size-700-c-stove-glass","title":"Ceramic Fireplace Glass Cut to Size | 700°C Stove Glass","description":"\n\u003cp\u003eSCHOTT ROBAX® is a lithium aluminosilicate glass-ceramic with a thermal\nexpansion coefficient of essentially zero — 0 ± 0.3 × 10\u003csup\u003e-6\u003c\/sup\u003e\/K\nacross 20–700°C. That single number is why it survives in a firebox.\nA panel can sit at 700°C in the center while the frame edge stays near room\ntemperature, and the material does not move enough to build stress. Tempered\nsoda-lime glass fails at roughly a third of that differential.\u003c\/p\u003e\n\n\u003cp\u003eIt also passes heat rather than trapping it. ROBAX® transmits strongly in\nthe shortwave infrared band — the part of the spectrum you actually feel as\nwarmth — so a closed firebox still radiates into the room instead of venting\nits output up the flue.\u003c\/p\u003e\n\n\u003cp\u003eUsed in wood stove and fireplace viewing windows, pellet stove doors,\nboiler sight ports, pizza oven and commercial broiler windows, and industrial\nfurnace inspection glass. Compared to borosilicate 3.3, which tops out near\n450°C, ROBAX® runs continuously at 700°C and peaks at 760°C. Compared to\ntempered soda-lime, it will not shatter on thermal shock — but note that\nit is \u003cem\u003enot\u003c\/em\u003e tempered and cannot be. It breaks into shards, not dice, and\ndoes not qualify as impact safety glazing.\u003c\/p\u003e\n\n\u003cp\u003eSupplied cut to your dimensions from full ROBAX® sheet in 3mm, 4mm and\n5mm (0.118\", 0.157\", 0.197\"). Dimensional tolerance ±0.5mm. Edges seamed\nas standard; ground, polished, radius corners, notches and holes available.\nSend a drawing or a template of your old panel.\u003c\/p\u003e","brand":"Canal Glass Shop","offers":[{"title":"Default Title","offer_id":67102467031085,"sku":"CG-CERFIRCUTTO-3853-001","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0728\/2740\/4333\/files\/75_9cc86712-93ec-4d90-83f8-84c0c6096310.jpg?v=1784799702","url":"https:\/\/www.glasshop.net\/de\/products\/robax-ceramic-fireplace-glass-cut-to-size-700-c-stove-glass","provider":"Canal Glass Shop","version":"1.0","type":"link"}
