Do you know the mineral Petalite? We wish it was linked to PTAL!
Do you know the mineral Petalite? It is a lithium aluminium phyllosilicate, also called “castorite”. Of course, the name does not originate from the PTAL project, it was actually discovered 200 years ago. You can learn more about Petalite on its Wikipedia page for example.
