{"product_id":"10355","title":"Dioptase, silicate de cuivre","description":"\u003cp\u003eDioptase is well suited as a pigment because of its not too high hardness. The complex copper silicate has a good light fastness, but discolors by heating - possibly even strong sunlight is enough. The mineral is very rare, especially the procurement of larger crystals for pigment production is difficult. Dioptase has a hardness of 5, which makes it suitable for use as a pigment.\u003c\/p\u003e","brand":"Kremer Pigments","offers":[{"title":"10 g","offer_id":44482235531334,"sku":"10355.12010.104","price":88.9,"currency_code":"USD","in_stock":true},{"title":"50 g","offer_id":44669943939142,"sku":"10355.12050.104","price":404.05,"currency_code":"USD","in_stock":true},{"title":"100 g","offer_id":44669943971910,"sku":"10355.12100.108","price":754.1,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.newyorkpigmentco.com\/fr\/products\/10355","provider":"New York Pigment Co.","version":"1.0","type":"link"}
