Spodumene Substitute Size:2 kg Manufactured by United States GypsumOur source of Spodumene is a substitute that is produced synthetically by Laguna Clay Co. Spodumene can be considered a lithium feldspar. That means that this material is a good source of lithium in both clay bodies and glazes. Spodumene contains a natural combination of silica, alumina, and lithium, which means that it melts a bit more readily than lithium carbonate. In glazes, spodumene can lend itself to the development of copper blue toned glazes
