You must understand that the anatase in the VM came from either
Mozambique or the north island of New Zealand. Inger has sent the
URL's and she is omnipotent.
Mike and Peter,
ALL TiO2 existing around the world in lava sand,
in feltspat, in ordinary sandpits and other TiO2 depots, in for
example China and the European Alps consists of Rutile and Anatase.
The big difference is that Rutile which in perfect cases could and
should contain 100% TiO2 with some Anatase and some Rutile usually
hold less than 100% TiO2 and that it's Rutile which many production
industries wants which actually means that Anatase is heated(!) to
950 degrees where it turns to Rutile. Rarely the other way round.
Need I really remind you all that the Alp sand used to dry ink and
the clay which is one part in the Medieval(and Ancient) color
production contains anatase...
