It is used as a source of lithia, and is often used as a replacement for feldspar.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eLithium, serves two main purposes in ceramics: it is a very powerful flux, and it also lowers thermal expansion of a glaze, helping to better fit a claybody and stop crazing. Spodumene differs from lithium carbonate in chemical makeup, as spodumene contains a natural combination of silica, alumina, and lithium, which means it melts more readily than lithium carbonate on its own.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eIn glazes, spodumene can lend itself to the development of copper-blue toned glazes and promote a matte surface -- this, in spite of being a strong flux, which is precisely what so many potters find appealing about the material.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eIn clay bodies, some potters use spodumene as a replacement for feldspar (though it technically IS a feldspar). This additive reduces the vitrification temperature required for a body to mature, and also reduces thermal expansion.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003ci\u003eFull bag is 50lbs\u003c\/i\u003e\u003c\/p\u003e","brand":"Laguna Clay Company (CA)","offers":[{"title":"1","offer_id":51481947275547,"sku":"1710","price":27.25,"currency_code":"USD","in_stock":true},{"title":"5","offer_id":51611808170267,"sku":"LAG-S3820D-5","price":115.59,"currency_code":"USD","in_stock":true},{"title":"10","offer_id":51611808203035,"sku":"LAG-S3820D-10","price":216.56,"currency_code":"USD","in_stock":false},{"title":"50","offer_id":51611808235803,"sku":"LAG-S3820D-50","price":946.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0952\/6896\/2587\/files\/Screenshot2025-09-17125123.png?v=1758135118","url":"https:\/\/archiebrayclay.com\/products\/spodumene-lbs","provider":"Archie Bray Clay Business","version":"1.0","type":"link"}
