Notes

Has lower lithium than petalite, spodumene and lepidolite.
While the term lithium feldspar is commonly used in the ceramic industry, there is no such thing (for example, in references that list various types of feldspar, no lithium material appears). The lithium ion is too small to be a part of the feldspar crystal structure.
