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 stoneware low iron bodies, while Darvan 811 high fire slips and red low fire slips or iron rich bodies. \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":"Laguna Clay Co.","offers":[{"title":"Default Title","offer_id":48185642549411,"sku":"rdk1790057222772","price":7.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/1787\/6643\/files\/darvan-7-pint_1.jpg?v=1790057231","url":"https:\/\/dripcoffeepot.shop\/products\/darvan-7-pint","provider":"My Store","version":"1.0","type":"link"}
