Designed for artistic ceramics, it contains melting minerals that develop a seductive surface with dark spots of different sizes and shades that stand out in an ivory-white matrix. Its high grog content provides excellent behaviour during drying and firing. Decoration with transparent glazes is ideal to enhance the vividness of the speckled effect.

To avoid it, it is recommended to fire the biscuit at a higher temperature (1050-1080ºC \/ Cone 04) and increase the soak time. If you work directly in single firing, the problem does not arise.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"SIO-2","offers":[{"title":"Default","offer_id":49265276584251,"sku":"14 910 201","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/7539\/6411\/files\/luna-speckled-stoneware-125kg.jpg?v=1723157212","url":"https:\/\/maacaffestore.com\/products\/luna-speckled-stoneware-clay-27-6lbs-cone-5-7","provider":"The Compleat Sculptor, Inc","version":"1.0","type":"link"}
