I also noticed that Pough reports spodumene as being thermoluminescent, but no color was given (at least in my version). Also, my version of Dana's Manual has no entry for petalite, but doesn't mean the property doesn't exist. Too many references to check.

Petalite can come much bigger than that, I've seen bigger in New Hampshire, USA.
