<HTML>Well, Grain is a carbo hydrate, Opal CT is a silicium dioxide. To get opal ct from a grain (burned or not) needs to replace all the different molecules in the grain with silicium dioxide. Its like fossilation, a process which is measured in geological ages.

Mineralisation is so slow that even 20000 year old mammoth bones are only fossilized to a very small extent.

But don't despair, Sandy will tell us next thad Davidovits has found out, that fossilation and opalisation only takes a few hours (and that the Earth is only 6000 years old).
