The picture that you have given of the views of Ken Towe, and others,
is not correct. The argument is that the particular form of anatase
reported by McCrone is not consistent with it being a natural product
and is consistent with manufacture by a synthetic process developed
after about 1920. Nobody is suggesting that anatase did not exist
before 1920. All they are doing is sating that the particular form of
anatase did not exist before 1920.

Nobody has argued that 800C was not attainable in the 15th century. Of
course it was. The objectionis to the suggestion by Olin that the
anatase on the VM was an accidental by-product of ink manufacture.
There are lots of reasons why that theory should be rejected, not the
least of which is that, as pointed out by Ken Towe, neither the ink
nor the ink maker is likely to survive the ink being heated to a
temperature sufficient to calcine the anatase.

Not only round and uniform but of a size falling within a limited size
range not typical of anatase as found in nature.
