Lithium carbonate is an extremely efficient flux in the formulation of glazes, as it lowers the melting point and facilitates vitrification. It is mainly used in high temperature glazes and to improve the thermal stability of parts.
It is also known to intensify colors, especially reds and pinks, in certain low-temperature glazes. The use of lithium carbonate in glazes can produce bright glazed surfaces and vivid colors, such as deep reds and purples.
Interesting Fact
Lithium has one of the lowest thermal expansion rates among the elements, which makes it a key ingredient for preventing cracking in glazed ceramics.
Helpful Tip
Since lithium carbonate can be volatile at high temperatures, use it sparingly to avoid affecting other glazes in the kiln. Also, make sure that the fired pieces are suitable for food contact if you use lithium glazes.
