Spodumene ceramic grade, used in glazes, is a 200 mesh material. How could the particles be big enough to glisten in the light? This is a micrograph of some of the particles from the 0.6% plus 100 mesh material that I extracted in a particle size distribution test. And 8% is plus 200 mesh. And all that material is flakey like this, millions of tiny mirrors. This also explains why the material becomes airborne so easily and why it is really not good to breathe this stuff in.
Spodumene is a lithium sourcing feldspar, an alternative to lithium carbonate to supply Li2O to ceramic glazes. Contains up to about 8% Li2O.
