Lithium Carbonate, Fine

$50.45

Ask us a question

Lithium Carbonate is the best source of lithium for making glazes. Lithium is a high temperature flux, which means that it causes glazes to melt at relatively high temperatures, and is typically used in small amounts (5% or less). Because it is alkaline, it tends to produce fluid glazes with glossy surfaces. Lithium carbonate reduces thermal expansion and increases a glaze’s firing range. Lithium also improves the brightness and durability of glazes.

Some potters may notice that their lithium carbonate containing glazes may have a tendency to pinhole or blister. This generally tends to happen when the lithium carbonate content is on the higher side, and it is caused by lithium carbonate's off-gassing during firing.

Chemical Formula: Li2CO3
