[Clayart] Calcined Rutile

I have never heard of anyone calcining rutile.
Pinholing can be a problem with rutile above 5 or 6%.
But, it is equally a problem with titanium dioxide used
in these percentages.
Therefore, logically, I have always considered that titanium
is the cause of the tendency to pinhole, not the organic
matter in the rutile.
