The really magic stuff is Amblygonoite which contains alongside Lithium, =
Phosphorus and Fluorine.
Unfortunately, because there is almost no commercial value from the =
point of mass production it is almost impossible to find. Some schools =
have stocks from way back but it seems to be absent from stockists =
lists.
My own favourite is Li mineral is Petalite from West Australia. =
Expensive but worth the investment to buy a full bag. Its higher silica =
content combines with Lithium to provide a good addition in small =
quantities to cure crazing.
Best regards.

Dear Ivor;
The Low melt spodumene from Tanco minerals in Canada contains the
mineral, amblygonite with its attendant P2O5.
