Petalite is a lithium aluminium silicate mineral (more simply lithium feldspar. It is valuable because it provides an insoluble source of lithium (lithium carbonate is soluble). Lithium is a strong alkaline flux and is effective over all temperature ranges. It and imparts lower expansion and gives unique colour response to copper and cobalt in glazes. .
Petalite can be used to create low expansion glazes. It is suitable for white and transparent glazes because of the low iron content. It does not present the frothing problems sometimes associated with Spodumene and helps improve brightness.
