It contains melting minerals that create a seductive surface with dark spots of varying sizes and shades, subtly standing out against the elegant ivory color. The high fireclay content ensures stability and safety during drying and firing, making LUNA Clay an ideal choice for both professionals and ceramic enthusiasts. Decoration with transparent glazes further enhances the speckled effect, giving your works a unique character.\u003c\/p\u003e\n\n\n \u003cp\u003eTo ensure durability and avoid chipping, which can occur as natural minerals absorb moisture, we recommend bisque firing at 1050-1080ºC (Cone 04) and extending the hold time. This allows the minerals to bond perfectly, ensuring LUNA Clay remains moisture-resistant and maintains its beautiful, authentic surface.\u003c\/p\u003e\n\n\n\u003cp\u003e For those who prefer a single firing, good news! LUNA is also perfect for this process. The high firing temperature completely fuses the minerals, eliminating the risk of chipping, and your work will maintain its beautiful surface without any surprises.\u003c\/p\u003e\n\n\n\u003cul\u003e\n\n\u003cli\u003e Temperature range: 1200-1260°C \/ cone 5-7\u003c\/li\u003e\n\n\u003cli\u003e \u003cstrong\u003eBisque firing: 1050-1080°C\u003c\/strong\u003e \/ cone 04\u003c\/li\u003e\n\n\u003cli\u003e Water content by weight: 19%\u003c\/li\u003e\n\n\u003cli\u003e Plasticity (IP Atterberg): 14\u003c\/li\u003e\n\n\u003cli\u003e Fireclay content: 35%\u003c\/li\u003e\n\n\u003cli\u003e Carbonate content (CaCO3): 0%\u003c\/li\u003e\n\n\u003cli\u003e Shrinkage on drying: 5.8%\u003c\/li\u003e\n\n\u003cli\u003e Shrinkage during firing: (1260°C): 5.3%\u003c\/li\u003e\n\n\t \u003cli\u003ePorosity (water absorption at 1260°C): 0.0%\u003c\/li\u003e\n\n\u003cli\u003e Fireclay size: 0-0.2 mm\u003c\/li\u003e\n\n\u003cli\u003e Dry bending strength: 2.7 N\/mm2\u003c\/li\u003e\n\n\u003cli\u003e Bending strength after firing at 1260°C: 29.2 N\/mm2\u003c\/li\u003e\n\n\u003cli\u003e Thermal coefficient 1250°C (25-500°C): 61.1x10^-7°C^-1\u003c\/li\u003e\n\n\u003cli\u003e \u003cspan style=\"font-size: 13px;\"\u003ePackage weight: 12.5 kg\u003c\/span\u003e\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Sio-2","offers":[{"title":"Default Title","offer_id":52522843275603,"sku":"SiO2 Luna","price":13.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/1409\/1859\/files\/luna-sio2-3_big_9816db72-6f71-4fc6-943a-4786e4075490.jpg?v=1764796268","url":"https:\/\/ceramiq.pro\/en-global\/products\/sio2-luna","provider":"Ceramiq.pro","version":"1.0","type":"link"}
