SPODUMENE Fine 325 Mesh
Spodumene
The name is from the Greek Spodos, meaning burnt to ash. Spodumene is a silicate mineral often referred to as lithium feldspar. Its mineral form is characterized by hard needle-like grains of brilliant white colour. It is used in ceramics as a source of Lithia. Lithia is a powerful flux, especially when used in conjunction with potash and soda feldspars. Li2O reduces thermal expansion, melting temperature and viscosity of the glaze melt. Spodumene can also be substituted for part of the feldspar complement in a recipe without disturbing overall chemistry.
An active flux usually used in small amounts in glazes. It is particularly useful where low expansion glazes are required. Also has been used in calcined form to produce flame proof bodies
