Spodumene is a lithium mineral that is used especially as a flux in the manufacture of ceramic glazes. Its main function is to lower the melting point of glazes, which allows them to melt at lower temperatures and facilitates the creation of more uniform and controlled coatings.
Spodumene is also valuable for its high thermal expansion capability, which makes it an ideal component for glazes used in high-temperature ceramics. This property allows glazes to better withstand thermal shock and reduces the possibility of parts suffering deformation or fracture due to rapid temperature changes.
Interesting Fact
In addition to its use in ceramics, it is a primary source of lithium, a metal that plays a crucial role in the manufacture of rechargeable batteries for electronic devices and electric vehicles.
Helpful Tip
Use spodumene if you are looking to improve the heat resistance and lower the melting point of your glazes. However, be aware that, due to its ability to expand, it can affect the compatibility between the glaze and the clay body, so preliminary testing is essential.
