The white primary clay deposits mined at Matauri Bay are derived from the alteration of acid volcanic rocks. The aluminosilicate feldspar minerals in the parent rhyolite have been broken down to their constituents by low temperature hydrothermal alteration and have then reconstituted as halloysite. Thus, while often called a kaolin, technically it is a halloysite.\u003c\/p\u003e\n\u003cp\u003eThe company has developed a unique beneficiation process (which includes filter pressing and thus the designation PFC or Premium Filter Cake) to ensure a high degree of purity for this New Zealand halloysite kaolin.

Small scale users have found it a little whiter burning than Grolleg Kaolin. It also supports translucency better. As a pure material, NZK is much less plastic than pure Grolleg (being barely plastic enough to wedge and roll into a slab, for example). However Grolleg requires about the same amount of bentonite (or VeeGum) compared to NZK to create a porcelain of the same plasticity. This New Zealand halloysite kaolin responds especially well to VeeGum to create very plastic porcelains that still dry very well. \u003c\/p\u003e","brand":"Sheffield Pottery","offers":[{"title":"1 Pound","offer_id":67286244524403,"sku":"RMNZK-1","price":4.4,"currency_code":"USD","in_stock":true},{"title":"5 Pounds","offer_id":67286244557171,"sku":"RMNZK-5","price":21.25,"currency_code":"USD","in_stock":true},{"title":"10 Pounds","offer_id":67286244589939,"sku":"RMNZK","price":41.5,"currency_code":"USD","in_stock":true},{"title":"25 Pounds","offer_id":67286244622707,"sku":"RMNZK-25","price":101.25,"currency_code":"USD","in_stock":true},{"title":"55 Pounds","offer_id":45113738756418,"sku":"RMNZKBAG","price":101.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/5508\/2050\/files\/8drqkkp5f5-400W_1b55e6d9-2454-45ba-900d-8c78bb3b51ae.jpg?v=1791876722"},{"product_id":"old-hickory-54-s-ball-clay-rmoldhic54s","title":"Old Hickory 54-S Ball Clay","description":"\u003cspan\u003e\u003c\/span\u003e\n\u003ch2 class=\"abz-seo-product\"\u003eOLD HICKORY 54-S BALL CLAY\u003c\/h2\u003e\n\u003cp\u003eThis ball clay is a multi- purpose clay that has excellent pressing, extrusion, and casting qualities.
