{"product_id":"darvan-7-pint","title":"Darvan #7- Pint","description":"\u003cp\u003e\u003cspan\u003eDarvan 7 is a deflocculant that is similar to sodium silicate. However, unlike sodium silicate, Darvan 7 does not erode plaster molds. As a deflocculant, Darvan 7 weakens the electrical attraction between clay particles and thus acts as a thinning agent in slips and as a general dispersing agent for clay bodies and glazes. It is mainly used to enhance the fluidity of casting slips and maintain or slow the shrinkage rate. Darvan 7 is typically preferred with porcelains and high iron content clay, while Darvan 811 can be used for stoneware, high fire slips and red low fire slips.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eSlips that are prepared with Darvan 7 show little tendency to thicken on standing, which is why it is often used in glazes. Darvan 7 can also be added to joining slip, which is ideal because it allows one to use less water and results in less shrinkage at attachment points.\u003c\/span\u003e\u003c\/p\u003e","brand":"The Ceramic Shop","offers":[{"title":"Default Title","offer_id":43765161656429,"sku":"CH-DAR7P","price":7.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0646\/3986\/0845\/files\/large-darvan-7-pint.jpg?v=1765390576","url":"https:\/\/www.sundownclaycompany.com\/products\/darvan-7-pint","provider":"Sundown Clay Company","version":"1.0","type":"link"}
