I like the scientific part here.
I know minerals very well.

I have also made Citrine out of Ametyst many times as a experiment, by warming up Ametyst. :)

When i saw the post first, i must admit that i did not actually expected the one that write it to know the chemical form of it and so.

I am impressed. :)

Thanks for sharing, even if i am not so sure about all the details about how to use it.
But i will not say it is wrong, because i have never researched that part.
